I met the same problem. Hope this is just bug
https://pasteboard.co/IMic7VB.png

[alexvkru]

Hello, All! Me too met the same trouble. I have Windows 10 1803, build 17134.1184, VS Community 2019 16.4.2 and .Net Core SDK 3.1.100 (both, for x86 and x64). When i create new project WPF (.Net Core) I have similar error MSB4062 about file “file:///C:\Program Files %28x86%29\dotnet\sdk\3.1.100\Sdks\Microsoft.NET.Sdk.WindowsDesktop\tools\net472\PresentationBuildTasks.dl". But this file exists in file system. What can I do for fix it?

[vatsan-madhavan]

Can you please share MSBuild binary logs corresponding to your failure?

https://aka.ms/msbuild/Binary-Log

[alexvkru]

Hello, Vatsan Madhavan. Yes, of course. I created new project "WPF App (.NET Core)", named this as "wd". In opened VS IDE I see the not working constructor window with XAML editor below. In next second i see error, described above.

I made the binary log, please find the attached files (the log-file and the picture with the output from msbuild with errors)

out.zip

Thank's you!

[vatsan-madhavan]

@alexvkru Thanks for the prompt response and the log - I appreciate it.

Is there a chance you could reproduce this problem on an English language system, or set your UI locale to English and reproduce the problem again so that the msbuild logs are generated in English? I tried looking through the logs but it's going to take me a very long time to translate the strings in the log ad-hoc from Russian to English and investigate the problem that way...

[alexvkru]

@vatsan-madhavan Hello, Vatsan! I'm now out of my work computer. I'll return at Jan/19/2020 and will make new binary log in English UI. Thank's You!

I updated Visual Studio to version 16.4.3 but the problem still remains

[vatsan-madhavan]

Paging @nguerrera @dsplaisted, the problem could be related to the URI encoding of (x86) in file:///C:\Program Files %28x86%29\dotnet\sdk\3.1.100\Sdks\Microsoft.NET.Sdk.WindowsDesktop\tools\net472\PresentationBuildTasks.dll

Assembly::LoadFrom doesn't seem to like the URL encoded form either:

Going through the logs, Pbt.props is setting $(_PresentationBuildTasksAssembly) to C:\Program Files (x86)\dotnet\sdk\3.1.100\Sdks\Microsoft.NET.Sdk.WindowsDesktop\tools\net472\PresentationBuildTasks.dll. After that, very next (and only) refererence to PresentationBuildTasks.dll is when MarkupCompileTask1 is about to run, and the UsingTask element is executed to load the DLL.

At this point, somehow (for reasons I don't understand yet) msbuild seems to be encountering AsssemblyFile=file:///C:\Program Files %28x86%29\dotnet\sdk\3.1.100\Sdks\Microsoft.NET.Sdk.WindowsDesktop\tools\net472\PresentationBuildTasks.dll in the following UsingTask declaration:

[alexvkru]

Hello! How i can reproduce it from Visual Studio? I set Platform Target in the Project properties to "x64", but still have error. I want compile project and for x86 platform too, if some people use x86 operating systems. Thank's!

[puchs]

@alexvkru : Could it be that the x86 SDK is listed in your PATH variable ahead of the x64 SDK? I think you might need to swap the PATH entries if you intend to target x64.

[alexvkru]

Hello, @puchs! Yes, there are a part of my %path% from Developer Command Prompt:
C:\Program Files (x86)\dotnet\
C:\Program Files\dotnet\
If i swap this two strings, may be i can to compile a x64 project. But trouble with x86 still remains...

May be, I want too much to make new WPF project in .Net Core. Now I compelled to work with .Net Framework 4.7.2 again.

[vatsan-madhavan]

@rainersigwald Thoughts/updates on this? Should we be opening a new issue against msbuild? Looks like WPF on x86 is pretty much broken in 3.1 (though its not clear whether it is broken for everyone, or just broken on some systems depending on environmental factors).

/cc @dotnet/wpf-developers

[rainersigwald]

Yeah, let's track this in MSBuild for now.

[rainersigwald]

This issue was moved to microsoft/msbuild#5090

[vatsan-madhavan]

I think I have an idea about what may be going on:

Let's see how $(_PresentationBuildTasksAssembly) is defined:

https://github.com/dotnet/wpf/blob/b30a16a465c9a0ed7e641a9d55df2f6e5c878a81/src/Microsoft.DotNet.Wpf/src/PresentationBuildTasks/Microsoft.WinFx.props#L5

It uses an MSBuild property function to normalize a relative path.

Now, this is what the documentation says about using property functions:

String values returned from property functions have special characters escaped. If you want the value to be treated as though it was put directly in the project file, use $([MSBuild]::Unescape()) to unescape the special characters.
...
In static property functions, you can use any static method or property of these system classes:

System.Byte
...
System.IO.Path
...
Microsoft.Build.Utilities.ToolLocationHelper

I think the problem here is that WPF ought to be un-escaping $(_PresentationBuildTasksAssembly), but it is not doing so.

What I don't understand is why, when MSBuild escapes results of path property functions by default, then it isn't able to handle escaped paths in UsingTask. Nevertheless, as long as this has always been the behavior of UsingTask (i.e., inability to handle escaped paths is not a recent regression/bug in UsingTask), I think WPF should be fixing this rather than having MSBuild handle it via https://github.com/microsoft/msbuild/issues/5090.

@rainersigwald does this analysis look right to you ? Can you also confirm that this isn't a recent regression in MSBuild/UsingTask ?

[rainersigwald]

We talked about this offline, but yes--that analysis sounds right to me.

[sloter69]

Replace line:

<_PresentationBuildTasksAssembly Condition="'$(_PresentationBuildTasksAssembly)'==''">$([System.IO.Path]::GetFullPath('$(MSBuildThisFileDirectory)..\tools\$(_PresentationBuildTasksTfm)\PresentationBuildTasks.dll'))</_PresentationBuildTasksAssembly>

with
<_PresentationBuildTasksAssembly Condition="'$(_PresentationBuildTasksAssembly)'==''">$(MSBuildThisFileDirectory)..\tools\$(_PresentationBuildTasksTfm)\PresentationBuildTasks.dll</_PresentationBuildTasksAssembly>

in file Microsoft.WinFx.props.

Works for me.

[vatsan-madhavan]

@sloter69, this is what we really want there:

    <_PresentationBuildTasksAssembly Condition="'$(_PresentationBuildTasksAssembly)'==''">$([MSBuild]::Unescape($([System.IO.Path]::GetFullPath('$(MSBuildThisFileDirectory)..\tools\$(_PresentationBuildTasksTfm)\PresentationBuildTasks.dll'))))</_PresentationBuildTasksAssembly>

[vatsan-madhavan]

@ASuurkuusk, please look for updates here - I've closed #2483 in favor of this issue.

[vatsan-madhavan]

This has been fixed via #2487 and will be part of 3.1.3 update.

[wstaelens]

@sloter69, this is what we really want there:

    <_PresentationBuildTasksAssembly Condition="'$(_PresentationBuildTasksAssembly)'==''">$([MSBuild]::Unescape($([System.IO.Path]::GetFullPath('$(MSBuildThisFileDirectory)..\tools\$(_PresentationBuildTasksTfm)\PresentationBuildTasks.dll'))))</_PresentationBuildTasksAssembly>

anyone wondering where to find this:

the file to edit could be found at C:\Program Files (x86)\dotnet\sdk\3.1.102\Sdks\Microsoft.NET.Sdk.WindowsDesktop\targets edit Microsoft.WinFx.props

[alexvkru]

Hello, All!

Thank's for help!

.Net Core SDK 3.1.3 still not available. I modified Microsoft.WinFx.props file and very glad to see 0 errors in new Net Core WPF empty project :)

[MikeRosoft]

What is the current status of this issue? It is still occurring to me when using .NET Core SDK 3.1.102.

• Edit: I have fixed this bug by installing .NET Core SDK v3.1.201 for x86.
