msbuild MSBuild does not resolve WindowsBase correctly

Describe the bug

I am working with third-party components (DevExpress) and their new release based on .NET 6 appears to have exposed a potential bug in MSBuild's assembly resolution logic. There appears to be a versioning conflict between two WindowsBase DLLs in the WindowsDesktop and NETCore SDKs. For further details, please see this public support ticket. In particular, this reply.

The issue applies to both .NET 6 and .NET 7 WindowsDesktop projects.

To Reproduce

Here is a sample project you can build to reproduce. Just build it and look in the Visual Studio build output to see the below lines.

@RobThree I think it would be better to file that as a separate issue because it likely has a different root cause and has to be fixed and tested separately.

Jan 27 '23 09:01 KalleOlaviNiemitalo

@KalleOlaviNiemitalo I figured out it had to do with MySQL.Data 8.0.32 (so, yes, this is unrelated, sorry, my bad).

Jan 30 '23 14:01 RobThree

Has this issue been resolved? Which version of Visual Studio can I build without encountering these warnings? Thanks.

Apr 07 '23 01:04 hyke123

@hyke123 It has not been resolved as of the latest VS version (17.5.3). No one from MS has commented here on the issue yet - still waiting.👀

Apr 10 '23 18:04 EatonZ

Maybe dotnet/sdk would be a better fit for this. There are some issues that sound related, for instance WindowsBase NETCoreApp vs WindowsDesktopApp Do not autoreference WindowsBase.dll in Microsoft.NetCore.App

Apr 11 '23 15:04 BrightLight

To circumvent this error, you may try to look at project.assets.json to help identify if some dependency is bringing in old Windows base version and then update this dependency accordingly. HTH

I actually fixed this with

<UseWPF>true</UseWPF>

Sep 15 '23 15:09 dedale

@dedale Thanks for the suggestion, but I do not use that file, and my project is WinForms and not WPF.

This issue still happens as of today. Hopefully something will be done for .NET 8?

My project is WinForms too so I enabled both 🤷‍♂️ . Otherwise you'll see in VS in framework dependencies of your project that WindowsBase is only taken from NetCore.App (in version 4). My finding is that when you also enable UseWPF, NetCore.WindowsApp dependencies also include WindowsBase is version of your tfm i.e. 6 or 7).

@dedale Unfortunately just adding that to my csproj breaks the project:

I have the very same issue with the WindowBase Assembly resolution but with a different kind of project (Maui Blazor Hybrid App) and running on .NET 8. Also adding <UseWPF>true</UseWPF> will totally break the project.

I also face this error in one of my projects. I found that when referencing an assembly that depends on WindowsBase version 6, the conflict happens. I can reproduce this in a very simple project, using both .NET 6 SDK and .NET 8 SDK.

I have no desire to enable UseWPF in this project, as this project has no UI layer.

Interestingly enough, when changing the Reference into a PackageReference, the warning is gone. Even though Visual Studio references the same full path of the dll.

In this particular situation i am not able to use a PackageReference to the file i need, i need to use an assembly reference.

Why does an assembly reference cause WindowsBase 4.0.0.0 to be included?

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <TargetFramework>net6.0-windows10.0.19041</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <Reference Include="C:\Users\username\.nuget\packages\system.reactive\6.0.0\lib\net6.0-windows10.0.19041\System.Reactive.dll" />
  </ItemGroup>

</Project>

Still has this issue in .net 8.0.402 sdk.

Any progress should we know?

I am using only Microsoft.Web.WebView2 and Newtonsoft.Json in my project.

I've identified that the issue is caused by Microsoft.Web.WebView2 starting from version >1.0.2792.45. Currently, I am using an older version.

Old version

With version 1.0.2739.15, there are no issues whatsoever.

Latest

With the Windows App Packaging project, another error appears.

@sefinek well sorry, it seems project.assets.json files are not helpful in your case to identify the source of the conflict 😒

Nov 01 '24 16:11 dedale

@dedale I've identified that the issue is caused by Microsoft.Web.WebView2 starting from version >1.0.2739.15. Currently, I am using an older version.

This was helpful, but in my case I was able to get rid of the mass of build warnings by flipping Microsoft.Web.WebView2 from 1.0.2849.39 to 1.0.2792.45.

@dedale Yeah, I checked that file earlier... These errors are preventing me from publishing my app to the MS Store ): @sir-wilhelm Indeed, in 1.0.2792.45, this issue is not present. Interesting.

Version	Warning	Error
1.0.2903.40	✅	✅
1.0.2849.39	✅	✅
1.0.2792.45	❌	✅
1.0.2739.15	❌	❌

1.0.2739.15 is the only good version that does not cause any warnings or errors.

Updgrade the project

Nov 04 '24 04:11 Nabibhr

Dropping back to v1.0.2739.15 removed this warning for me also. Thanks

Nov 19 '24 10:11 Paul-Williams

The latest version of Microsoft.Web.WebView2 1.0.2903.40 still produces the warning, so I'll be sticking with 1.0.2792.45 for now.

Yep, I'm wondering why this hasn't been fixed yet. With the latest version of Microsoft.Web.WebView2 installed, it's impossible to publish an MSIX package to the MS Store, as yet another error appears.

I've updated my https://github.com/dotnet/msbuild/issues/8289#issuecomment-2452637397 to highlight the versions that encounter issues with the WinAppPackagingProject etc.

I'm getting the same issue here on a Library that uses WebView2 and net6.0-windows as the target framework. I just get the warning but I'm not sure if I should push to nuget (or if it even allows me to)

@sir-wilhelm - Although there have been other reasons given, in this thread, for this conflict. Can you confirm WebView2 v1.0.2792.45 does not produce this warning/error for you? I fell back to WebView2 v1.0.2739.15, in my project, but perhaps needlessly I went back too far?

@Paul-Williams I first noticed the build warning starting with 1.0.2849.39, so I went back to 1.0.2792.45 to get rid of the warning. I can't say I've run into the error others have.

It should be easy for you to try 1.0.2792.45 in your project/solution and run a build to see.

Microsoft.Web.WebView2最新版是1.0.3296.44，把版本降到1.0.2792.45，这个警告就消除了，具体原因未知。
