Running .net5 tests failed because .net5 framework was not found

[pmatuszewski]

Description

Before environment update I was able to run tests for .net5 application.
Currently when tests are run following error is displayed:

Testhost process exited with error: It was not possible to find any compatible framework version
The framework 'Microsoft.WindowsDesktop.App', version '5.0.0' (x86) was not found.

• The following frameworks were found:
  3.1.26 at [C:\Program Files (x86)\dotnet\shared\Microsoft.WindowsDesktop.App]
  6.0.6 at [C:\Program Files (x86)\dotnet\shared\Microsoft.WindowsDesktop.App]

Image version and build link

Environment: windows-2019
Version: 20220614.0

Is it regression?

20220606.1

Expected behavior

It should be possible to run tests for .net5 application

Actual behavior

Running tests fails

Repro steps

1. build .net5 project with tests using msbuild
2. run tests e.g dotnet test apptests.dll

This is expected behavior as runtime component was upgraded from 5 to 6 recently https://github.com/actions/virtual-environments/pull/5749/files

@timheuer could you please suggest what is the best possible option to solve the issue?

[timheuer]

@pmatuszewski .NET 5 is out of support, but you can at your own control install it on your run. Using the setup-dotnet action and specify the 5.0.x version to install prior to your subsequent commands.

[pmatuszewski]

Thanks for your response. Unfortunately installing .NET 5 with setup-dotnet didn't solve the issue. The same error is returned when tests are run.

@pmatuszewski is this a public repo? I think I'll need more info to see what's going on here -- the Desktop aspect is probably the cause here but I don't know why. My .NET 5 projects are running/testing fine: https://github.com/timheuer/ClassLibrary2/runs/7007951826?check_suite_focus=true -- so I'm not sure what the diff is here (in mine using windows-2019 runner image, and both projects target net5.0)

@pmatuszewski, Any updates?

I am planning to close the thread. If you have any concerns feel free to open it.

Hi,
I have the same error.

The issue is that we cannot run net50 x86 test with the latest image.

On my project:
this run worked with image version 20220925.1
And not working on this run with image version 20221027.1

[reegeek]

In fact, when a runtime is integrate to a image, x64 and x86 version are installed.

With dotnet-setup you cannot specify x86.
