I recently upgraded visual studio from version 2017 to 2022.
Now I'm having some very annoying problems.
I have a c#.net WPF project with about 25 usercontrols, all in the same namespace (MyProject.Usercontrols)
When one usercontrol won't compile, I will get an error for every instance of every usercontrol, saying that that usercontrol does not exist in namespace MyProject.Usercontrols.
So I get a list of hundreds of errors that I know are wrong. It can take me a while to find the actual error causing the problem. When I fix that one error, all of those namespace errors disappear.
Sometimes it won't even show me the real error and I get nothing but incorrect namespace errors. (I literally couldn't find the problem so i just had load an old backup and try again)
I never had problems like this is version 2017. Is there a setting I can change?
I've searched hard but i cannot find any thread with the same problem.
I'm not sure how to deal with this, I'm tempted to just go back to version 2017.
Maybe ask a different question, why are these namespaces failing at all? I've moved wpf projects from 2017 to 2019 to 2022 and haven't experienced this issue to this or any degree. I would advise to be more proactive and anticipate what will fail based on what you have seen so far.
If you are overwhelmed, create a single project and move one control into it (controls should stand on their own right?), determine its issue, and verify that your other controls do not follow the same failure pattern.

I started encountering this issue about 3 days ago after an update that I randomly clicked on when I was in Visual Studio Code. Whenever I try to access HttpRequest.Query from the Microsoft.AspNetCore.Http namespace, I get an the following error message: "Entry Point was not found".
I have not been unable to fix this and this has interrupted my ability to work. I've talked this over with my teammates, and they are not encountering this issue at all.
I've tried pretty much everything I could google and think of.
Auto Generating Bindings
Deleted and re installed every Nuget Package at C:\Users{username}.nuget\packages
Deleting and reinstalling everything about Visual Studio and Visual Studio Code
Using the most recent versions of Microsoft.NET.Sdk.Functions
Deleting the bin and obj folders of my project
Removing unused references in my project
At this point, I'm not even sure what's really wrong any more. I found a post with my EXACT SAME issue, but the way the person fixed it did not apply to me:
Azure Functions .NetCore 3.0 Request.Query throwing "Entry point not found" error
Some Info- may or may not be useful.
When I go through the code step by step in the debugger, HttpRequest.Query shows up properly with all of the keys. I'm wondering if there is some kind of name conflict between HttpRequest object from Microsoft.AspNetCore.Http vs System.Web
If I set my project to use the most recent version of Microsoft.NET.Sdk.Functions, I get a new error instead of an entry point error, I get this instead:
I'm using Visual studio Code.
Can anyone assist? I'd be happy to provide any information needed!
I gave up. I spent about 3 days trying to solve this and this was affecting my ability to work. I just had my entire laptop reformatted and that "fixed" the issue. I tried pretty much everything I could find and nothing worked and I couldn't wait any more. Best of luck to anyone who encounters this!
I am working on a small project involving a wpf-based UI program when I come to a intellisense problem. It constantly complains that several identifiers (class/method/property) cannot be found, and most of those are from another assembly. Similar issue has been asked by many other users of visual studio:
WPF assembly reference missing - project still building
Type or namespace cannot be found, when reference does exist
Getting "type or namespace name could not be found" but everything seems ok?
If the promble only happens on types in referenced assemblies I might just overlook it. But now even some types in the same assembly are determined 'missing' by intellisense. Today I created a new custom Window in this wpf project, and visual studio auto generated code for further use as follows:
public partial class ReceiveTest : Window
{
public ReceiveTest()
{
InitializeComponent();
}
}
Then intellisense told me that identifier 'InitializeComponent' cannot be found, and every control this window owns cannot be found either. This is really upsetting since it makes intellisense completely useless. Normally these 'missing' identifiers are declared in FileName.g.i.cs and managed by visual studio itself, however it seem visual studio somehow failed to recognize it.
Now I have done everything I can including solutions given in above links but failed again and again. Could anyone explain this problem and show me a way to solve it? I would be very very grateful.
P.S. I am using visual studio 2017 and PowerTool addon
Upgrading Test project from 2010 to 2017
Following this up on a recent problem with a test project on VS2017 after upgrade from 2010. Tried everything to get rid of the squiggly red and they wouldn't go.
Problem was that 'namespace.zone.section' had 'namespace' not found when it was there and seen by intellisense etc (and in some cases 'zone' or 'section')
Deleted sou files
Deleted project files
Deleted the references
Reapplied all after clean, restart, restart
server and all the above.
Still problem persisted.
So I deleted the test project (imported form 2010) recreated the project in 2017, copied all the original test classes into new project, added back all the other projects (supporting the tests), added moq etc back in. Only took about 20 mins.
And ... compiled and worked.
Conclusion was that the original project file (test project) had something in it that didn't get upgraded and screwed it all up. Anyway it is all fine now.
I post this so you don't have to wast your time.
I'm trying to rename a C# namespace in Visual Studio 2015, and after a moment Visual Studio helpfully (?) tells me there are 216 unresolvable conflicts.
That's all the information it seems to provide, though.
How can I see what these conflicts actually are?
The preview button doesn't show anything obvious.
I have spent a lot of time but concluded that there is no way to see the conflicts but in all of the encounters I found out that it is because of one of the Documentation Comments Tag. The rename somehow is unable to rename values inside these tags.
I'm using Visual C# 2008 Express. This is the first time I've had this error in years, the last time I had it was around the time I started programming.
I have no idea what it actually means or why it suddenly came up, it seems rather ambiguous for what the error message says. All I know is that throughout my app, I inherit a lot of the main windows from a ThemedWindow class I came up with to give them a custom appearance, there are no errors in that code and everything was working 100% perfect 20 minutes ago.
The error in full:
Warning 12 The designer could not be shown for this file because none of the classes within it can be designed. The designer inspected the following classes in the file:
InheritingWindow --- The base class 'ThemedWindow' could not be loaded. Ensure the assembly has been referenced and that all projects have been built. 0 0
I get that for every form that inherits from ThemedWindow, and several other errors because the project won't build far enough for everything else to work.
Just before this happened I updated the font on all forms and sub-controls, the project even built and ran after I did that, then this happened for absolutely no clear reason.
I've tried the classic rebuild it, delete build files, reopen Visual Studio etc, but nothing seems to work at the moment.
Does anyone know how to fix this?
Build your base usercontrol class with AnyCPU option.
These problems were caused by an unfortunate bug in Visual Studio. I had other errors (not warnings) in some code, even though nothing else directly depended upon it, which played a part in this whole situation.
I could be wrong in explaining it but here's what I think went wrong: for some reason (bug), it totally forgot about unchanged objects it had already compiled before, gave me the actual errors I had in my code, and a bunch of other warnings because it wouldn't go past that point. I couldn't get into the designer for forms that depended upon ThemedWindow because I'm guessing ThemedWindow hadn't recompiled before these errors occurred.
Once I commented out the erroneous code as a quick fix and rebuilt the solution, everything compiled successfully.
As of writing this, this seems to be working properly in VS 2019 16.11.13.
It is not, however, working in VS 2022 17.1.6...
In VS 2022, I tried all the other fixes mentioned here, or they were not relevant:
AnyCPU is already set on the solution, never changed from that
The base class was never modified since it last worked, and so wouldn't need to recompile (plus this seems a moot point since it works fine in VS 2019)
While changing the base class temporarily to System.Windows.Forms.Form did get rid of the original error, it popped up a load of other errors of missing framework references and other non-problems.
The project is referencing .Net 4.8, (latest at time of writing this) and is not different from VS 2019 to VS 2022. Either way, can't reference non-existent newer version, and I doubt referencing an older version would fix this without breaking much more.
I saw a fix somewhere else of running VS as administrator and then rebuilding. This also did not fix the issue.
So I guess my fix for this is to downgrade from VS 2022 to VS 2019...
In my case (VS 2015 Pro) none of the above helped. Only after changing the target framework to different (specifically newer, from 4.5.1 to 4.5.2) and recompiling did the Forms Editor load the form.
Before changing the target framework I tried cleaning the solution, removing and adding the references (the base user control was in different dll), manually deleting all bin and obj folders after cleaning the project, restarting VS, all to no avail...
I have this problem too, with VS 2019 version 16.11.2, so I guess this bug will never be fixed.
My workaround, since my BaseForm class does all its work through code at runtime and has no functionality that would affect the designer, is that when I need to use the designer, I just temporarily change my window's base class. That is, change--
partial class MainWindow : BaseForm {
to
partial class MainWindow : Form {
then do the design stuff, and then once the designer is closed, put BaseForm back.
This may work for you if your base form class also doesn't do anything that would have an effect in the designer.
I'm having a bit of trouble here, in our company we have a self rolled DA layer which uses self referencing generics. In Visual Studio 2010, the IDE was perfectly happy with this, however 2012 seems to be having difficulty, even though when we build, it succeeds.
Here is an example:
The DataObject definition is as follows:
[TypeDescriptionProvider(typeof(HyperTypeDescriptor.HyperTypeDescriptionProvider))]
public class DataObject<T> :
INotifyPropertyChanged,
IDataErrorInfo,
IEditableObject,
IDataObject
where T :
DataObject<T>,
new()
I realise it isn't the simplest of definitions, but its legal, and it builds perfectly fine.
However, this 'issue' causes intellisense to fail, as well as the 'Go To Definition' function, which needless to say is frustrating.
I've tried removing and re-adding the references, but the issue persists.
VS2010 is perfectly happy and is what I have gone back to using, VS2012 is very nice and responsive but if this issue persists its a deal breaker.
Anyone got any ideas?
Want to make a couple of things clear, this issue is an intermittent one (which is a pain as its really hard to track the root cause).
It breaks intellisense and 'go to definition' everywhere, not just for the class with the error.
I'll have a go at building a example solution to submit to connect, but time isn't on my side lately.
This can happen if you open the same solution/project with two instances of Visual Studio (even two Visual Studio 2010 for example). The Intellisense mechanism uses .NCB files that Visual Studio instances cannot really share. In this case, Intellisense behavior is strange.
Sounds silly, but I run into similar issues with new code that gets introduced or changed with intellisense. I tracked it down to basically needing to perform a save all, or sometimes even clean and rebuild / compile before it intellisense properly acknowledges the code being valid.
A similar that happens on occasion in VS2010 too that can be duplicated if you make a class structure, then edit code on another class to use it, then bounce back, hack out class functions and add new ones without any saving.
Sometimes, and this isn't always the case ReSharper can cause issues with references and GTD functionality. Do you have it installed?
