I'm working in VS 2008 and have three projects in one solution. I'm debugging by attaching to a .net process invoked by a third party app (SalesLogix, a CRM app).
Once it has attached to the process and I attempt to set a breakpoint in one of the projects, it doesn't set a breakpoint in that file. It actually switches the current tab to another file in another project and sets a breakpoint in that document. If the file isn't open, it even goes so far as to open it for me. I can't explain this. I've got no clue. Anyone seen such odd behavior? I wouldn't believe it if I wasn't seeing it myself.
A little more info: if I set a breakpoint before attaching, it shows the "red dot" and says no symbols loaded...no problem...I expect that. When I attach and invoke my .net code from SalesLogix and switch back to VS, my breakpoint is completely gone (not even a warning that the source doesn't match the debug file). When I attempt to manually load the debug file, then I get a message that the symbol file does not match the module. The .pdb and the .dll are timestamped the same, so I'm stumped.
Anyone have any ideas?
Thx,
Jeff
I saw this functionality in older versions of VS.Net (2003 I think). It may still exist in current versions, but I haven't encountered it. Seems that files with the same name, even in different directories confuse VS.Net, and it ends up setting a break point in a file with the same name. May only happen if the classes in the file both have the same name also. So much for namespaces I guess.
You also may want to check your build configuration to make sure that all the projects are in fact building in debug mode. I know I've been caught a couple times when the configuration got changed somehow for the solution, and some projects weren't compiling in debug mode.
Kibbee, you were right! It was two files with the same name in different folders. I was setting the breakpoint in the correct file on line 58 - it was putting the breakpoint on the other file at line 58. I was finally able to set a breakpoint by using the "Debug-->New Breakpoint-->Break at Function Name" menu option and entering my function name. It stopped exactly like it should have then.
I agree - so much for namespaces, right? Damn thing cost me a couple of hours. Oh, well...at least it's solved and I know why.
Thx for the answer and thx to Matt for his reply, too!

Here's the error message that I'm getting on a breakpoint in my razor code:
A copy of index.cshtml was found in App_Web_cmi1k1de.dll (Server-side
symbols), but the source code is different from the version built into
App_Web_cmi1k1de.dll (Server-side symbols). To allow the breakpoint
to be hit when the source is different blah blah blah...
I was getting a very similar error message and I went to the Configuration Manager in my solution and found that one project wasn't set to "debug." I changed it to debug, cleaned out everything in C:\Users\me\AppData\Local\Temp\Temporary ASP.NET Files\root\932eeb02\b9cdc481\, and rebuilt my solution. I see that now in this folder I see a
C:\Users\me\AppData\Local\Temp\Temporary ASP.NET Files\root\932eeb02\b9cdc481\App_Web_cmi1k1de.dll
together with a
C:\Users\me\AppData\Local\Temp\Temporary ASP.NET Files\root\932eeb02\b9cdc481\App_Web_cmi1k1de.pdb
These two files have identical timestamps, down the second. Any idea why I'm getting this error? It doesn't make any sense that the source code would be different than the compiled .dll.
Stop debugging, check that the IIS (or IISExpress) process is no longer running - stop it if required, in Visual Studio right-click the solution Clean, then rebuild. Try debugging again.
Visual studio on your view file, right click properties, Copy to output directory: Copy if newer or Copy Always
None of the above worked for me. Restarting VS did not work either. Turned out to be related to a recent change I had made to another file. Even though that complied OK, when I undid the change, the error went away.
Hello there, Stackoverflow.
Recently, when I've been programming in Visual Studio 2010, I've been getting the problem with VS locking the bin/Debug/(ProjectName).exe file when trying to build and gives me the error below after trying to build the project 10 times:
Unable to copy file "obj\x86\Debug\TileEngine.exe" to "bin\x86\Debug\TileEngine.exe". The process cannot access the file 'bin\x86\Debug\TileEngine.exe' becuase it is being used by another process.
The problem appears when I edit the source and then try to Debug.
I've checked using different programs, and the only program using the file is Visual Studio.
If I wait for about 10 minutes before trying to build, it seems to work properly, but when trying different things, it isn't good needing to wait 10 minutes before trying something.
I've tried different solutions both on this site as well as everywhere I can find on Google.
Some solutions I've found, but haven't worked for me
Solution 1 - Using a pre-build script
In some different questions here on Stackoverflow, I've found one solution being that you go into Project Properties > Build Events and then in the Pre-build event command line add:
if exist "$(TargetPath).locked" del "$(TargetPath).locked"
if not exist "$(TargetPath).locked" move "$(TargetPath)" "$(TargetPath).locked"
This made it possible for me to build the project one more time than I usually could, but when editing the code again, and then building, the same error appeared.
Note: Trying to build a release instead of a debug build seems to break the pre-build script and it exits with the code '1', which seems to make VS unable to build properly. Removing the pre-build script makes it work like "normal" again, still with the same error though.
Solution 2 - Running Visual Studio as Administrator
This is another solution I've found, but havent worked either for me, so I assume that Visual Studio already have all the permissions required and running as Administrator doesn't actually make any difference.
Solution 3 - Changing the AssemblyVersion
In this question, Visual Studio build fails: unable to copy exe-file from obj\debug to bin\debug, I found another solution that included changing the AssemblyVersion, in the Properties\AssemblyInfo.cs file, to "2.0.0.0".
This, however, haven't made any difference whatsoever for me.
Solution 4 - Closing UserControl designers before building
According to some different answers here and there on the Internet, Visual Studio apparently uses the built project executable to render the UserControl designer(?). In my case, this is probably not it, though, since I use XNA mostly and it doesn't use the UserControl designer.
Solution 5 - Cleaning up resources when application quits
This might be a solution that I have failed to implement properly. I'm just thinking though, that if this is the solution, how come I haven't been required to do it before. I assume XNA unloads everything that gets loaded through the Content pipeline, therefore this solution wouldn't' make any real sense.
If there is anyone that is able to spread some light on this issue, it would be really awesome, as it is stopping me from programming anything really, because I don't like waiting for 10 minutes because I've made a 2 second change all the time.
I've run into this problem a few times myself.
Mine might not be from the same cause as yours, but I'll tell you what went wrong with me and how I fixed it, hopefully it'll be helpful to you.
Basically, my program never fully exited properly, even when it appeared to. It would continue to run, and thus continue to lock down the file.
A quick dirty fix I used initially (and a way to prove if this is the case) is:
Open Task Manager (Ctrl-Alt-Del)
Click Processes tab
Look for your program's name (TileEngine.exe)
Note: There will probably be name_vshost.exe (TileEngine_vshost.exe) That's a VisualStudio thing, ignore that, it's not relevant.
If you find it, it means your program hasn't actual exited fully.
If it's there, click on it and press "End Process"
So if it's there, then for some reason, your program didn't shut down, like mine did.
Often, this is from a thread being launched and forgotten, or an Async task that never completes, or something like that.
Make sure in your OnExiting(..) void function that you kill all running threads.
If your program is still running despite best attempts to close all threads and other blockers, you can use the very dirty bad method:
In OnExiting(...) run the code "System.Diagnostics.Process.GetCurrentProcess().Kill();" - this will taskmanager-style forceshutdown the current process... this is only as an emergency I-can't-make-it-work-any-other-way method.
I think I found the solution myself.
In the Project Properties, "Enable the Visual Studio hosting process" wasn't checked. Checking it seems to have fixed the problems, at least for now.
Got reminded of it from mcmonkey4eva's post. So thanks for that =)
And thanks for the other replied I've got. Stackoverflow is awesome!
Have you checked if any files are being blocked by your firewall? When I switched to the full version of Avast I find I have to disable the File System Shield It loves to remove my executable files when I try to run my visual studio projects.
I had problems when upgrading to VS2012 Professional. (SDK, .Net, Visual C++ Redistributable package)
ENSURE ALL OF THESE ARE COMPATIBLE WITH THE CURRENT VERSION OF VS YOU ARE USING
What I did, was I ended up uninstalling EVERYTHING that was associated with both Visual Studio downloads. If you are able to remove and save your project files elsewhere and then bring them back. Go through all your program files to see if there is anything hidden in the wrong folder and check your C drive.
Which meant downloading and reinstalling (fresh):
I think if you clean out your program files, it should be ok. I wouldn't recommend going into your register unless you are very sure of what you are doing. IF you have already made changes to the register then we'll have a look at that and other options (if this doesn't solve your problem).
Try removing the readonly check from your solution by unchecking at the folder level.
I ran into this problem and in my case was due to having bin included in the solution; as soon as I excluded the bin folder from my solution the problem went away.
Nothing helped, not prebuild commands, neither designers closing, but I figured out a way that helped me, just changing from debug to release and vice-versa releases locked files and you can delete them without closing the IDE.
I regularly get this problem if I switch from Debug to Release and then immediately F5 to compile. Crazy as it sounds, waiting for, say, one minute after switching between modes will prevent this.
If it's locked, the only solution is to close Visual Studio and re-open.
I solved this problem organizing my resources on solution. I noticed this error when I put some images on my application at the same solution folder.
So,
I'd removed all images and resources from app, save without it.
Moved the images to outside Solution folder.
Open the solution and add this images again, using "Import" button at controls.
If you will try this, remember to do with Application Icon, on Project Settings.
Now, everything is working fine for me.
I hope it helps.
You need to disable Windows Indexer as it locks up the file
Follow this Guide how to disable
In my case the problem seem to be caused by the remote debugger. It starts on local machine when you compile with "x64" option. Try to change the project setting (properties/buid) until you reach the final version.
Change Build Platform target from x86 to Any CPU.
I can't seem to be able to debug. When I try to, I don't get any build errors, and the layout changes to debug mode, but the windows never pops up. I have an orange bar at the bottom of VS, which I think is standard, but nothing happens after that. It's not just in the project I'm working on. I have started a new WFA and tried to debug without adding any code and the same thing happens. Anybody have similar issues?
I've encountered this before. Not sure what causes it, but generally it is one of a couple of things to fix it.
make sure you are building in debug and not release
close VS, go to the project's dir and delete the obj and bin directories. Reopen in VS and rebuild.
there is an option under tools - options - build (iirc) that allows for checking if source is same as code file. However, you should see a message in output window if this is the case.
on the project properties in the build (iirc) you can throttle the pdb file from full debug symbols to no pdb at all. If you are not the only person on the project check this setting still has full pdb enabled (low probability this got changed though)
make sure you're on the right platform that you are building to (x64 vs x32)
...lots more, but a starting place...
Addendum as per comment...
So, those messages are good. It is saying there are no problems (but it sounds like you already know that :) ). I would start with the general debug options you mention. Do this on a hello world app. That way you can troubleshoot the lowest common first. Here are my settings. Try to match them and see if that works. For example, I know "ask before deleting breakpoint" is irrelevant, but "break all processes when one process breaks" is important. So, I just added them all to make it easier to troubleshoot.
ALso, make sure you are getting a red dot here like so in your code in visual studio (I've seen instances where VS won't let you put this here):
Right click on the project
Click on the properties.
go to web.
Check the Box for Enable Edit and Continue .
Hope that helps :)
This is an issue with visual studio 2012. It doesn't ALWAYS show up. I've found that if you stop your program during debugging, or if you close the console window, this will almost always trigger.
However, letting it run to completion isn't enough either, sometimes this just happens.
Also you can build your application in debug mode, go to the output, run the program, and attach to that process. :P
Amazing answers already given but they dont help in the purpose. So here is my finding, no matter if i am late in answering, but it really works for me.
Even if you are developing a web app, just go to the website properties by right-clicking the project and then you see a "Web" tab on left as i have highlighted. Then just check the box saying "Enable Edit and Continue". Thats all you need to do. it works for me!
I had a similar problem, and solution was absolutely dumb. VS was confused with two instances of Internet Explorer in “Browse with” setting. So, I set Google Chrome (any browser) as default, and then set IE as default again. It deleted the other instance of IE (only one remained) and debugging was enabled.
Hope it help!
I had a similar issue.
I added up:
using namespace std;
and this solved the problem
For me, uninstalling the Redgate's Reflector plugin that had expired fixed it. I spent more than 4 hours uninstalling, rebooting, reverting to older code, etc etc..
When my default browser was changed to CHROME, I could no longer debug my User Interface. Setting IE back to the default browser fixed it. Alternatively you can attach the process plug-in during debug.
I had the same problem with my desktop application and as this forum says you should mark your project as a startup project, since visual studio has unmarked. It worked just fine for me an I believe it will help other people that may have this problem, since I believe you have finished this project.
One of my VB .NET Winforms projects wouldn't allow debugging.
This was due to the configuration manager set to 'Release' even though the toolbar dropdown indicated 'Debug'.
You need to select the mode dropdown and select the last option 'Configuration Manager' and ensure that the main project is set to 'Debug' and not 'Release'
Install Microsoft SSDTSetup.exe 450Kb and Close the SSDT tool during install. After installation open the SSDT tool and execute the script task and Component with breakpoint. Worked for me
try checking your output without debugging
Ctrl + F5
good luck
I keep getting the same message whenever I right click a scenario and "Generate Step Definitions" or "Go To Step Definition".
It worked the first time I tried, but it hasn't since.
I've filed a bug report, but in the mean time, anyone know how to solve this?
Over five years later and I'm getting the same problem... Here is the solution that worked for me:
Close the solution in Visual Studio.
Go to your temp directory in Windows Explorer (enter %temp% in the location bar).
Delete the 'specflow-blah-blah.cache' file.
Reload the solution in Visual Studio, rebuild the solution and give SpecFlow a bit of time to sort itself out.
ive gotten this issue before, we have about 800 SF tests in one of our projects and when we first load it can sometimes take quite a lot of time for it to load up. For me its always sorted itself out eventually.
Another thing to try would be to upgrade to 1.9 which came out a few days ago, it may have improved performance.
Although I'm using the last (1.9.2) I had the same problem. Re-opening VS2010 solved the issue.
I've found a work around for this problem; close the solution and delete the .SOU file. Re-opening the solution then re-creates this file and the SpecFlow context menu options then work.
I got the the same issue when I moved external assemblies to specflow.json file from app.config
1) Turned out that I got an assembly reference which didn't even have specflow nugets.
2) I renamed one assembly, but for some reasons the old name wasn't replaces in AssemblyInfo.cs file. I changed it manually, cleaned the project. Cleaned the specflow cache (see previous answers how to do this) and it worked.
So, check if all the references and assembly names are correct.
Cheers
P.S. Don't forget to setup "Copy to Output Directory" option for specflow.json :D
If you are still unable to force the steps to bind, but just need to get to the definition of a given step:
Place a breakpoint on the first step of the scenario
Debug test
Step into the function (F11 by default)
There you are! VS navigation may not work but the debugger knows the way:)
I get this may not be a direct solution to the original issue with steps not binding, but I think it gets where the OP wanted to go...
The root cause of this issue is your code has poor performance and that cause the slowness and hangs your Visual Studio or due to low performance of code Visual studio moves in unresponsive state.
The solution is improve the performance of your code. You need to optimize your code in all the possible ways:
Use less inputs in each step
Use less parameters in your parametrized methods
Avoid unnecessary loops
Divide the number parameters into more methods if taking more than 5 parameters. It will improve the performance.
Divide the input values into more sub-step or separate steps, it will improve the performance and speed of the code.
Use switch case instead of if else statements if there are more cases.
Free up the occupied memory if the reference variables or objects are no more of use.
Read data from external sources and store them into objects or lists locally and minimize make it one time read from external source once and access the values copied locally in the lists or any other objects/variables.
Close or quite the external files or call to them after use.
Hope this is the best way to improve the performance of code and this issue will not happen for sure and your steps bindings and definition will be more smooth and easy.
We fixed it like this:
close Visual studio
Deleted the obj and bin folders under the project(s),
open Visual studio again.
rebuild
After that the .feature files "came back to life"
I'll give you 2 versions of my problem to describe it, first the short version.
When I try to build my application it does that perfectly and my app works but when I try to rebuild it, that fails and gives an error message saying that 2 files are missing (bin/debug/MusicPlayer.exe and bin/debug/MusicPlayer.pdb). When I then try to build normally, it fails to with the same error.
Now the longer version:
The way this happened was quite out of nowhere, I program on 2 different locations (both in Visual Studio 2010 sp1) but to always have the recent version in the right place I copy the entire solution folder to a usb stick, this folder I copy over again on the other PC and use it to continue were I left off, I've done this many times without problem. Yesterday however, I got an exception while testing the app. But instead of showing this in my code, it was complaining that it could not find the program.cs file (it was there, but apparently it had a different checksum (md5) and it asked me to use this one. After a while I found what part of my code caused the exception and fixed it. Since then I haven't got that error anymore. But when I later tried to rebuild instead of build, it gave me the error described in the short version. I have tried to fix it, but apparently I was not very successful.
Basically, what I think it does is delete the files in the debug folder that need rebuilding and then gives me the error of missing files (the files that it deleted) and thus failing to rebuild succesfully because these deleted files the normal build option won't work to.
(What I then do is re-copy them from my usb to make the normal build work).
Don't know if it's important, but I program in C# and I'm still learning.
Also when I copied it to my usb I believe I had no errors and the app was working fine (except the part I fixed later, which I could not test at that location). And when I build the entire solution it gives some warning ==> "Assembly 'bun/debug/MusicPlayer.exe' is incorrectly specified as file" and this for 5 files.
Does anyone know how to fix this rebuild problem and if necessary the warnings?
Thanks in advance
(and sorry for my bad English)
OK it seems like you might be confusing yourself with your directory structure here. If you want to add Content or Resources (Images, Text Files, etc.) you should place them in a folder within your project (not called bin or obj). All your build files will go here. Instead place the Content in another folder and Right Click -> Properties and Set the build action to "Content" or "Resource" and set the Copy to Output Directory (bin folder) to "Do not Copy" or "Copy if newer."
The project is failing because you have the built executable "MusicPlayer.exe" in your project. So Visual Studio is trying to build an executable file in adding to the project. Restructure your directories or remove "MusicPlayer.exe" ever time your build your project.
Do you have any anti-virus software running? They can go way too aggressive on removable drives. You are actually continuously deleting and creating a runnable program on usb stick by recompiling.
Just a guess tho...
Sounds to me like you have a pre- or post-build event with a hardcoded path in it. Fix that using variables and it should be ok.
