Description

Getting the following error while trying to run MSTests that are being hosted in a console application assembly

Microsoft (R) Test Execution Command Line Tool Version 16.11.0 Copyright (c) Microsoft Corporation. All rights reserved.
Starting test execution, please wait... A total of 1 test files matched the specified pattern. [MSTest][Discovery][MSTestPlayground.exe] Failed to discover tests from assembly MSTestPlayground.exe.

No test is available in C:\Users\niboger\source\repos\MSTestPlayground\bin\Debug\MSTestPlayground.exe. Make sure that test discoverer & executors are registered and platform & framework version settings are appropriate and try again.

Additionally, path to test adapters can be specified using /TestAdapterPath command. Example /TestAdapterPath:.

Same here, I'm trying to run unit tests within a project having exe output type. Using 2.1.2 everything works just fine, but with 2.2.7 and 2.2.8 I get the same error.

Same for me, 2.2.5 still works but from 2.2.6 on it's not working anymore.
