I am new to JustMock, I try to use it in .NET5 but failed, I have seen some articles related to this kind of problem but I failed to resolve it. At the same time, I use MOQ for this project, I have tried TypeMock before but have already uninstalled.

    Test method  threw exception: 
    Telerik.JustMock.Core.ElevatedMockingException: Cannot mock 'BitCoinLib.Database.Connection'. The profiler must be enabled to mock, arrange or execute the specified target.
    Detected active third-party profilers:
    * {324F817A-7420-4E6D-B3C1-143FBED6D855} (from process environment)
    Disable the profilers or link them from the JustMock configuration utility. Restart the test runner and, if necessary, Visual Studio after linking.
  Stack Trace: 
    ProfilerInterceptor.ThrowElevatedMockingException(MemberInfo member)
    MocksRepository.InterceptStatics(Type type, MockCreationSettings settings, Boolean mockStaticConstructor)
    ProfilerInterceptor.GuardInternal(Action guardedAction)
    Mock.SetupStatic(Type staticType, StaticConstructor staticConstructor)

Hello Francis,

I see that you are using an advanced (elevated) mode unit testing, so in this case, the framework requires the JustMock profiler to be loaded in order to succeed. The exception message states that some other profiler is loaded at the same time, which is not allowed by the runtime.

What can be done?

Some googling around the GUID from the error description points me to a tool for monitoring web applications. Since JustMock does not have integration (more details can be found in this article) with this tool, you have to find a way to disable it, I suppose that it could be achieved via some settings or extension menu options inside Visual Studio.

I hope this information helps. If you are still facing any troubles I will be glad to assist you further.
