Running `dotnet test` fails with System.ComponentModel.Win32Exception (SDK 10.0.101)

[0xced]

Describe the bug

After upgrading from the .NET SDK 10.0.100 to 10.0.101, running tests started to completely fail.

Steps To Reproduce

1. Make sure that both the .NET SDK version 10.0.100 and 10.0.101 are installed to be able to fully reproduce.

2. Clone the https://github.com/0xced/nugraph repository with submodules

git clone --recurse-submodules https://github.com/0xced/nugraph

3. Ensure that the commit is 26c592425f5b0310e6359e091681d2e121e9e9d0

cd nugraph
git checkout 26c592425f5b0310e6359e091681d2e121e9e9d0

4. Ensure that the SDK version 10.0.100 is used

dotnet --version
10.0.100

5. Configure for Release through the Configuration environment variable

export Configuration=Release

6. Run the tests

dotnet test

The output should look like this:

Running tests from tests/nugraph.Tests/bin/Release/net8.0/nugraph.Tests.dll (net8.0|arm64)
tests/nugraph.Tests/bin/Release/net8.0/nugraph.Tests.dll (net8.0|arm64) passed (10s 500ms)

Test run summary: Passed!
  total: 30
  failed: 0
  succeeded: 30
  skipped: 0
  duration: 5s 561ms

7. Edit the global.json file and update the .NET SDK version to 10.0.101. It should now be this:

{
    "$schema": "https://www.schemastore.org/global.json",
    "sdk": {
        "version": "10.0.101"
    },
    "test": {
        "runner": "Microsoft.Testing.Platform"
    }
}

8. Run the tests again

git clean -fdx
dotnet test

Expected behavior

The tests pass, just like with the SDK version 10.0.100

Actual behavior

The tests completely fail.

The following exception occurred when running the test module with RunCommand '/home/runner/work/nugraph/nugraph/tests/nugraph.Tests/bin/Debug/net8.0/nugraph.Tests' and RunArguments ' --report-trx --report-trx-filename TestResults-net8.0.trx --results-directory /home/runner/work/nugraph/nugraph':

I'm a bot. Here is a possible related and/or duplicate issue (I may be wrong):

• dotnet test issue in azure pipeline #7059

[0xced]

The crucial part seems to be the Configuration environment variable which is set to Release but the test runner wants to pick the Debug version which does not exist.

Thanks for reporting. That looks serious, and I don't see any obvious mistake in your code. We will have a look as soon as possible.

running in wsl using ubuntu 20_24, I don't see the problem.

Trying with 24_04, and 8.0.416 runtime, which is probably what effectively runs

[0xced]

running in wsl using ubuntu 20_24, I don't see the problem.

Note that I edited the original issue to add step 5 when I figured out this was the crux of the issue:

export Configuration=Release

I don't see that line in your reproduction steps.

This bug is very unfortunate for me because all my .NET GitHub actions are designed with the Configuration environment variable set to Release in order to avoid repeating the configuration at each step (dotnet build --no-restore, dotnet test --no-build, dotnet pack --no-build)
