TestRunner: Application JetBrains.Rd.Tasks.RdFault
Answered
When running unit tests with ReSharper I'm getting the below exception. The tests run fine with Visual Studio's native test runner.
I am using Visual Studio 2019 16.7.2 and ReSharper 2020.2.4.
The tests are running .NET Core 3.1.

Hello,
Please set the following setting ReSharper | Options | Tools | Unit Testing | General | "Default .NET Framework version:" to the "Automatic" value.
Also, the behavior is fixed in the 2020.3 and the setting different from "Automatic" doesn't affect running the tests in .NET Core projects.
Hello Richard J Hughes,
Thank you for contacting us! Do you test an UWP application by any chance? Could you get a ReSharper log and share it alongside a support ticket? You can create one by the "Submit a Request" button above.
Please run ReSharper with logging enabled, start VS devenv.exe executable with the following options, then reproduce the issue and share the C:\log\resharper_log.txt log file.
I've run into this issue as well and have submitted request 2997159 with the verbose logfile
Hello Andrey Simukov
Your suggestion to change the default .NET Framework Version to Automatic worked.
Thanks!
