✅ dotnet test: Testing with VSTest target is no longer supported by Microsoft.Testing.Platform

Running dotnet test produces the following error: 
c#
Testing with VSTest target is no longer supported by Microsoft.Testing.Platform on .NET 10 SDK and later. If you use dotnet test, you should opt-in to the new dotnet test experience. For more information, see https://aka.ms/dotnet-test-mtp-error

I am using TUnit, and it is constructed on top of Microsoft.Testing.Platform, any idea what might be going on? I checked the link, and gloabl.json includes the necessary config 
{
  "sdk": {
    "allowPrerelease": true
  },
  "test": {
    "runner": "Microsoft.Testing.Platform"
  }
}
{
  "sdk": {
    "allowPrerelease": true
  },
  "test": {
    "runner": "Microsoft.Testing.Platform"
  }
}

This is the output, no error, looks like global.json is not respected

hamarb123•4w ago
I assume you have the global.json in the project directory or above, and haven't overridden it with another one closer to the project?
Core
CoreOP•4w ago
there is a single global.json at root level, also the sdk "allowPrerelease": true takes effect test config seems to be ignored yes, there's no overriding

try adding <UseMicrosoftTestingPlatformRunner>true</UseMicrosoftTestingPlatformRunner> to the test project csproj @Core and then try also adding <TestingPlatformDotnetTestSupport>true</TestingPlatformDotnetTestSupport> maybe if that doesn't work also, ensure the OutputType is Exe I think is what you want for MTP, could be that also, not sure once you get it working, you can remove the unnecessary changes

where do you set package version?
Core
CoreOP•4w ago
I also tried adding UseMicrosoftTestingPlatformRunner, but same result I'm using central package manager

hamarb123•4w ago
are you running dotnet test on the project, or the solution btw?
Core
CoreOP•4w ago
It is odd, because tests execute from the IDE, but fail from command line on this specific project
hamarb123
hamarb123•4w ago
maybe try solution just in case, but probably won't work
Core

it doesnt :Smadge:

hmm, why is it still using vstest lol have you got the global.json next to the sln or next to the csproj? (try putting it next to the sln, which is hopefully in a dir or 2 above the csproj, if not) anyway, it's late for me so I'm going to go to bed - hope you can get it working 🙂
