C# 8 introduces default interface method implementations. Attempt to mock such methods with JustMock in elevated mode fails. The following example illustrates the issue:

public interface IMyInterface
{
    int IntProperty { get => 0; }
}


[TestClass]
public class UnitTest1
{
    [TestMethod]
    public void TestMethod1()
    {
        var mock = Mock.Create<IMyInterface>();
        Mock.Arrange(() => mock.IntProperty).Returns(1);

        Assert.AreEqual(1, mock.IntProperty);
    }
}

The issue is present when JustMock extension is installed and the debugger is launched inside unrelated projects, for example, a blank console app. The extension should detect JustMock references from project settings and automatically disable this feature when it becomes inapplicable. Optionally the extension could give the way to explicitly disable the debug window from popping up by toggling the menu item.

Currently, the support for code coverage in the JustMock Azure Pipeline task includes only projects targeting .NET Framework.

Implement support for projects targeting .NET Core.

Currently, when the JustMock profiler is enabled it provides a performance hit on the test execution. This effect is expected because a profiler is involved.

What we can do is find a more optimized way of instrumenting the methods.

Docker is a container acting like an isolated environment. Research how the JustMock profiler can be registered into such container.
Hosted VSTS should work on the same principle. Research how the registry could be accessed through VSTS extension or other tools.

Currently, there are a lot of JustMock project templates with different targeted categories. There are templates targeting just one search category and there are other templates targeting different categories.

Optimize the templates to be available in all relevant search categories and lower their number.
