I have a successful build on 9 November 2022 and my tests are run by calling the following command:

dotnet test "C:\projects\myproject\BusinessTests\BusinessTests.csproj" --configuration Release --no-build /property:Platform=AnyCPU

Next, in the output I have:

Test run for C:\projects\myproject\BusinessTests\bin\Release\net6.0\BusinessTests.dll (.NETCoreApp,Version=v6.0)
Microsoft (R) Test Execution Command Line Tool Version 17.3.1 (x64)

Today (5 December 2022) I see the command is the same:

dotnet test "C:\projects\myproject\BusinessTests\BusinessTests.csproj" --configuration Release --no-build /property:Platform=AnyCPU

But the output is different for 17.4:

Test run for C:\projects\myproject\BusinessTests\bin\Any CPU\Release\net6.0\BusinessTests.dll (.NETCoreApp,Version=v6.0)
Microsoft (R) Test Execution Command Line Tool Version 17.4.0 (x64)

See how the platform (Any CPU) has been added to the location where the tool tries to find the DLL? At first I thought it was an issue with the test tool, but whe I run this locally, with the same version, it works fine. Any thoughts on what this could be?

    Hi Peter,

    It's because .NET Core 7.0 is the latest version that comes bundled with VS 2022.

    Two ways to fix the tests:

    1) To define which .NET SDK version is used when you run .NET CLI commands add global.json to the root of your repository with the following contents:

      "sdk": {
        "version": "6.0.300",
        "rollForward": "latestFeature"

    2) If you are configuring projects via UI then on "Build" tab of project settings remove "Any CPU" under "Platform" field to have "Project default".

    Thank you, that was indeed the fix.
