.NET 10 RC1: dotnet test calls fail when parameters end with .exe or .dll

[boris-yakhno]

Describe the bug

In the 10.0.100-rc.1.25451.107 .NET SDK, dotnet test calls fail if provided with parameters that end with .exe or .dll. This happens when providing the parameters directly as arguments to dotnet test and when providing them through an .rsp file, but with some differences. This does not happen on SDK versions 6-9.
This is a problem for us in JetBrains TeamCity, as it breaks existing integrations with dotnet test.

To Reproduce

Reproduction with command line arguments:

1. Create a test project.
2. Ensure the 10.0.100-rc.1.25451.107 .NET SDK is used for dotnet calls.
3. Run dotnet test -p:a=b -p:foo=bar.exe or dotnet test -p:a=b -p:foo=bar.dll.

Expected result: dotnet test succeeds.
Actual result: dotnet test fails with exit code 1 and the following output – The argument -p:a=b is invalid. Please use the /help option to check the list of valid arguments.

In the following cases, the call succeeds:

• No parameters ending with .exe or .dll are provided, e.g. dotnet test -p:a=b -p:foo=bar.txt.
• .NET SDK 6-9 is used (tested with versions 6.0.414, 7.0.401, 8.0.301, 9.0.100).
• dotnet build is called instead of dotnet test.

Reproduction with an .rsp file:

1. Create a test project.
2. Create an rsp.rsp file with the following content:

   /noconsolelogger
   -p:foo=bar.exe
   

3. Ensure the 10.0.100-rc.1.25451.107 .NET SDK is used for dotnet calls.
4. Run dotnet test @rsp.rsp on macOS or dotnet test `@rsp.rsp on Windows.

Expected result: dotnet test succeeds.
Actual result: dotnet test fails with exit code 1 and the following output – The argument /noconsolelogger is invalid. Please use the /help option to check the list of valid arguments.

In the following cases, the call succeeds:

• No parameters ending with .exe or .dll are provided, e.g. the .rsp file contains the following parameter: -p:foo=bar.txt.
• The parameter ending with .exe or .dll is enclosed in quotes, e.g. the .rsp file contains the following parameter: -p:foo="bar.exe".
• .NET SDK 6-9 is used (tested with versions 6.0.414, 7.0.401, 8.0.301, 9.0.100).
• dotnet build is called instead of dotnet test.

Further technical details

Tested on macOS arm64 15.6.1 and Windows x64 10.0.26100.

Possible fixed in #50926

Tested on latest rtm build and the error no longer reproduces. Fixed in the mentioned PR.

[boris-yakhno]

Hi @nohwnd, thank you for the fix!
I'm still getting this error on 10.0.100-rc.2.25502.107. Could you please let me know me if this is expected, and if yes, will the fix be included in the .NET 10 SDK release?

[nohwnd]

yes it will be in the final I was testing on the newest build I could find (from dotnet/sdk)
