In the Resources folder of my project, I have many different DLLs from other assemblies in my solution. These DLLs are used as embedded resources so I can have a single EXE without having to have local copies of all the DLLs. What I want to be able to do is have them updated every time I build my entire solution. So for example, if I have AssemblyOne/bin/x86/Debug/Foo.dll, I want the DLL to always copy over to LocalAssembly/Resources/Foo.dll whenever I build the project.
Is there an easy way to do this? I was looking at the post-build-event macros, but none of them would be able to directly reference my "LocalAssembly", which is not the Solution Directory. Also, I'm not sure how I would go about writing a new custom post-build command in a way that the newly copied DLLs would not be an absolute reference to my local machine. Thanks! Please comment for more information and I will edit the question.
You need not access only your solution folder in post build events. The post build scripts run with whatever permissions the compiler had when it ran. Since in Visual Studio things frequently run with Administrator permissions, chances are great you have access to your entire file system. As a result, if you are wanting to copy resources around, you merely need to presume that you are starting the xcopy call in the build destination directory. From there, you can navigate around with normal paths. So if, for example, you needed go up three levels and then into the directory LocalAssemblies, your copy command would look like xcopy Foo.dll ../../../LocalAssemblies.

I've recently coded a little program to determine numbers in a picture and it is reliant on two libraries I've used. (DLLs)
Since my target computer is not allowed to install programs due to security reasons, I need to create a portable .exe.
.NET is installed on the target computer but for some reason VS still does not include the libraries I've used in the exe but instead creates an application folder with a setup.exe, some .DEPLOY files and an application manifest.
I am new to VS and .NET in general so this question could be easy to answer, but I'm asking since I've found nothing useful on StackOverflow neither on google.
You can simply build the application and copy your bin/Debug folder along, but that would still mean you need multiple files.
In order to merge all references into the executable, use ILMerge. Here is some help calling ILMerge.
Basically, after building, you should do something like this:
ilmerge /target:winexe /out:SelfContainedProgram.exe
Program.exe ClassLibrary1.dll ClassLibrary2.dll
There is just one file you need to send along.
One way to do this is to build your application in Release mode (You can pick from Debug or Release in the drop-down). Then go to C:\Projects\[ProjectName]\[ProjectName]\bin\Release (The location of your project folder may vary). You'll see a bunch of files but all you really need are the DLLs, executable, and the config if you used one. You won't have to do any setup if you keep the necessary files in the application's folder, just copy them all to a folder on the target computer, create a shortcut if you want then you're good to go.
You can just copy all your assemblies into any folder you want. Simply chose "Build" from within Visual Studio and copy the files from bin/debug to your destination-folder.
However you have to ensure that all (relative) paths (if existing) still work as you cannot be sure where the user of your program copies the files to.
One simple way could be to use 7zip Packager, it doesn't need any installer. However, VisualStudio method might be more reliable.
I encountered the same issue recently. ILMerge suggestion above is no longer supported. I found Fody.Costura as a modern replacement.
Sorry, a bit of a noobish question here...spent an hour on Google and in MSs help documents, my head appears to be in the wrong place, I can't figure this out.
I have a C# project set up in Visual Studio 2012 that has references to a few .dlls that I have on my own hard drive (NetOffice .dlls to be specific, for Excel Interop). I've been adding them by right clicking on my references folder, going to Add Reference and then going to Browse to find the files. At that point they are included and everything works as expected on my side.
The problem occurs when I share the project. I'm using Git to keep the project coordinated between myself and a couple team members. I'll run my commit and push it then have my teammate do his pull. Everything shows up on his computer correctly, but when we open up the project it tells me that the NetOffice .dlls are missing.
I'm guess that this is because the files are only linked locally on my computer, but I can't figure out, for the life of me, how to make the .dlls exist in the file structure so that they travel with the project when I push it.
We have a few NuGet packages we use as well, and they seem to work just fine after being transferred. I've also gone into the .dll properties for NetOffice and turned "Copy Local" to true, yet it's still not included.
All I want is to be able to link references and then send the whole thing (dlls included) to my teammate, what am I doing wrong? I figured I would want to simply include the .dlls in the project structure but... I'm just not understanding something. Any help please?
1 Create a folder in the file system at the same level as the solution file.
2 Copy the external dll's to that folder.
3 Add a Solution Folder tho the solution.
4 Add each dll to the the solution folder using add existing item
5 Reference the Dll's in the solution
The steps 3 and 4 aren't really necessary, but they help to keep things organized.
Lets assume your source control root folder is called SourceRoot
and your solution files are under a folder called JaySolutionFolder
I prefer:
Adding a new folder to your source control, under SourceRoot, called SharedDlls
Copy all external Dlls to this Folder.
Add this dll references form SharedDlls to your project.
Commit this folder
Now your teammates have to get JaySolutionFolder & SharedDlls to compile the sources.
Later this SharedDlls could be target directory of Build process (Using tools like TFS Bulid, NANT or else)
This will be a way to minimize team based development problems.
In release and software installation, you can use installers or software package builders like installshield or Visual Studio Setup Package or ... to solve external dlls problem
Hop this helps.
Although it's not good practise to include binaries in your git repository, doing so will solve your problem.
The quick fix could be to create lib directories in sensible locations within your repository (I'm not a C# developer but Gama Felix's suggestion seems correct).
Then commit these folders and push to the server.
I'm new to using Visual Studio, and I'm trying to figure out how to 'publish' my program so I can move it other's computers and run it from there. I'm not sure if it makes a difference, but there are three projects in my solution. And if I publish it, will I still continue to be able to develop the original files etc?
Thanks a lot!
Ok, so you've written your code, debugged it and now you want to distribute it...
When you build a solution using Visual Studio the compiled output of each project is produced in a folder which is either specified manually, or, by default, in a bin folder relative to the projects root folder. Within this folder are subfolders which hold the output for a corresponding build (for instance the Debug folder contains the Debug compilation output).
If you have three projects then, for example, let's assume one is an executable application and the other two are dynamic link libraries on which the application project is dependent, the compiled output from the latter two projects will automatically be copied to the applications compiled output folder, meaning you only need to ship what is in this folder (along with anything else you actually know is required).
For a (rough) folder graph to try and visualise what I'm saying:
SolutionFolder\
ApplicationProjectFolder\
Bin\ <- contains overall output
Debug\ <- the compilation you develop with
Release\ <- the compilation you distribute (after testing)
DynamicLinkLibrary0Folder\
Bin\
Debug\ <- automatically copied to 'ApplicationProjectFolder\Bin\Debug'
Release\ <- automatically copied to 'ApplicationProjectFolder\Bin\Release'
DynamicLinkLibrary1Folder\
\Bin
Debug\ <- as above
Release\ <- as above
You can continue to work on your code after distributing, yes, of course, but you can hardly expect the users of the application to have your latest changes without redistributing the whole thing, or updating/patching et cetera.
Of course, this solution is the simplest form - ideally you'd want an installer project as part of the solution, which is the final distributable end-product.
As I said above, it seems you may need to know a heck of a lot more than this to proceed competently and confidently, and I could explain further details on each aspect mentioned here, no doubt, but it has to stop somewhere. Hope this gets you started, though.
Adding to the answer given by #Mr. Disappointment, you could also add a Setup project to the solution, which will take the compiled output and build an installer (a .msi file) for your program. You can then give the .msi file to your users and they can run the setup program to install the application on their computers. You can also put the .msi file on a network share or make it available for download from a website, depending on your requirements.
Another option is to investigate Visual Studio's ClickOnce deployment, which also allows you to distribute your application to users in a simplified way, via a web site or network file share.
I have a quick question regarding debug and release in VS 2008.
I have an app i've been working on - its not yet complete but the bulk of the functionality is there. So basically i'm trying to give a copy of it now to the person helping with documentation - just so they can have a play and get the feel for what i've made.
Now the question is how to provide it to them. I was told to just copy the .exe out of the debug/bin folder and put that onto USB. But when testing, if I run this .exe anywhere else (outside of this folder) it crashes. I've now worked out why this is:
var path = ConfigurationManager.AppSettings["PathToUse"];
var files = Directory.GetFiles(path);
throws a null reference, so that App.config file is not being used. If I copy that file in with the .exe it works again.
So actually my question is regarding the best way to manage this situation. What is the best way to provide a working copy to people, and, is there a reference on preparing apps for release - so everything is packaged together and installed in a clean structured folder heirarchy?
If you want to be safe grab everything in the debug/bin folder. If you use the drop down in VS to change to release and then compile the project, there will be fewer files in the release/bin folder because many debug related files are not included.
If there are third party DLLs you are referencing, like if you downloaded log4net or something like that, then you can simply put them in the same folder as the exe. This is called side-by-side deployment, and in my opinion is the simplest and easiest to test.
You can search for XCOPY deployment to learn more about what you are trying to do.
You can take another step of compressing the bin folder into an archive like a zip file to make it easy for the user to extract them, or you could use a tool like WIX or NSIS to create an installer to extract and copy the files.
For some reason, we have a script that creates batch files to XCOPY our compiled assemblies, config files, and various other files to a network share for our beta testers. We do have an installer, but some don't have the permissions required to run the installer, or they're running over Citrix.
If you vomited all over your desk at the mentions of XCOPY and Citrix, use it as an excuse to go home early. You're welcome.
The code currently has hundreds of lines like:
CreateScripts(basePath, "Client", outputDir, FileType.EXE | FileType.DLL | FileType.XML | FileType.CONFIG);
It used to be worse, with 20 int parameters (one per file type) representing whether or not to copy that file type to the output directory.
These hundreds of lines create upload/download batch files with thousands of XCOPY lines. In our setup projects, we can reference things like "Primary output from Client" and "Content Files from Client". I'd love to be able to do that programmatically from a non-setup project, but I'm at a loss.
Obviously MS does it, either using an API or by parsing the .csproj files. How would I go about doing this? I'm just looking for a way to get a list of files for any of the setup categories, i.e.:
Primary Output
Localized Resources
Content Files
Documentation Files
EDIT:
I have a setup project like Hath suggested, and it's halfway to what I'm looking for. The only problem keeping that from being a perfect solution is that multiple projects depend on the same assemblies being in their own folder, and the setup will only copy the file once.
Example:
Projects Admin, Client, and Server all rely on ExceptionHandler.dll, and Admin and Client both rely on Util.dll, while Server does not. This is what I'm looking for:
Admin
Admin.exe
Admin.exe.config
ExceptionHandler.dll
Util.dll
Client
Client.exe
Client.exe.config
ExceptionHandler.dll
Util.dll
Server
Server.exe
Server.exe.config
ExceptionHandler.dll
Since the referenced assemblies are all the same, what I get is this:
Admin
Admin.exe
Admin.exe.config
ExceptionHandler.dll
Util.dll
Client
Client.exe
Client.exe.config
Server
Server.exe
Server.exe.config
This causes a FileNotFoundException when either Client or Server can't find one of the two DLLs it's expecting.
Is there a setup property I'm missing to make it always copy the output, even if it's duplicated elsewhere in another project's output?
EDIT AGAIN: All referenced DLLs are set to "Copy Local", and always have been. I found a decent article on using NAnt and XSLT to grab the list of files, so that may be a possible solution as well, as neouser99 suggested.
ACCEPTED SOLUTION: I'm pretty much back where I started. All .exe and .dll outputs are put into a "bin" directory in the setup project, loosely packed. The other per-application folders contain shortcuts to the executable in that directory.
The difference now is, I'm going to add a custom action to the installer to use reflection, enumerate the dependencies for each executable output, and copy the .exe and .dll files to the separate directories. Bit of a pain, as I just assumed there was a way to programmatically detect what files would be included via some setup library.
why not use another setup project and just set the 'Package files' setting to As Loose uncompressed files (setup project->properties)? then share the folder.. or something.
edit:
I see, you have 3 folders for your outputs. but the setup project only detects the ExceptionHandler.dll and Util.dll once, so it will just pick the first folder and put it in there.
You could do a setup project for each project - bit annoying maybe..
You could manually add in the dll's to the projects that are missing the assembly's
either by adding in the File by 'add file' or 'add assembly' or 'add project output' if you have those projects in the same solution.. (I doubt that's the case though).
or just dump all of them into one output directory...
Although it's designed as a build tool, you might find NAnt to be extremely useful in what you are talking about. The tasks (build, copy, move, delete, etc.) that you can define allow for very fine-grained file lookups, up to general, full folders. If you also incorporate NAnt into your build process, I think you could find that it helps out in more ways then one.
Another approach that has worked for me in the past is to add the shared resource (Assembly, DLL or project) as a reference to each of the Admin, Server and Client projects. Then open the properties panel for the referenced item in each project and set "Copy Local" to true.
Now when you build the projects, each will have its own instance of the Assembly copied into its output folder.
This should also cause the shared components added in this manner to be replicated in each of the output folders in the setup package.
A completely different approach could be to set them up as symbolic links on the network share. A symbolic link is basically a short-cut where the file-system hides the fact that it is a short-cut, so all other applications actually believes that the file has been copied (http://en.wikipedia.org/wiki/NTFS_symbolic_link).
One advantage of this approach is that the file is updated immediately as the file changes and not only when you build your projects. So when you for instance save one of the config-files with a text-editor the update is applied immediately.
The following MSBuild script part can build your SLN file (you can replace it with .csproj) and will report a list of all projects that were build (Dlls, EXEs).
<MSBuild Projects="MySolution.sln" Targets="Clean; Rebuild" Properties="Configuration=$(BuildMode);">
<Output TaskParameter="TargetOutputs"
ItemName="AssembliesBuilt" />
</MSBuild>
Now, this doesn't really solve your problem, but it gets you a list of everything that was build. You also have copylocal, so you could probably just take AssembiesBuild and copy all DLL and .CONFIG files from there.
Example:
AssembliesBuild = c:\myproj\something1\build.dll
you'd go to c:\myproj\something1\ and simply search for all *.dll and *.config files and include them. You can do this pretty easily with MSBuild or powershell, if you have it installed. To output a XCOPY script from MSBuild, I think you'll need MSBuild contrib projct installed.
