I am trying to update a pulumi project from netcoreapp3.1 to net6.0. When I do this, clear out the bin and obj folders, and do a pulumi preview, the build runs Ok but then I am getting the following

error: an unhandled error occurred: Program exited with non-zero exit code: 3762504530

    Unhandled exception. System.BadImageFormatException: Could not load file or assembly 'Microsoft.Extensions.Logging.Abstractions, Version=6.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'. Format of the executable (.exe) or library (.dll) is invalid.
    File name: 'Microsoft.Extensions.Logging.Abstractions, Version=6.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'

       at Pulumi.Deployment.CreateRunnerAndRunAsync(Func`1 deploymentFactory, Func`2 runAsync)
       at Program.<Main>()

anyone have any suggestion on how to resolve this?

Can you "dotnet run" the project without pulumi (it won't work, Deployment.Run will error about no engine, but will test that the binaries are executable)

can you share your csproj? my base csproj looks something like this (i've upgraded to net7)
