Here's how you can find where an interface's members are used within a class implementation in Rider, especially when dealing with generics and constraints like public MyClass where T : MyInterface.

Rider provides several features to help you navigate and understand your code. The key is to leverage Rider's "Find Usages" functionality and type navigation.

1. Explicit Interface Implementation:

If MyClass explicitly implements MyInterface, you'll see the interface members implemented with MyInterface.MethodName(). In this case, you can directly search for these explicit implementations.

To find usages of IMyInterface.GetValue in Rider:

• Right-click on GetValue in the IMyInterface definition.
• Select "Find Usages". This will show you all places where IMyInterface.GetValue is called, including the explicit implementation in MyClass.

2. Generic Constraint Usage:

When you have a generic constraint like where T : IMyInterface, the methods and properties of IMyInterface can be called on instances of T within MyClass.

To find where IMyInterface members are used on T in MyClass:

• Right-click on GetData in the IMyInterface definition.
• Select "Find Usages". This will show you all calls to GetData, including the one within ProcessData in MyClass.

3. Navigating from the Generic Type Parameter:

You can also start from the type parameter T within MyClass.

• Place your cursor on T in MyClass.
• Use Rider's "Go To Declaration or Usages" (CtrlB or CtrlClick). This will show you where T is used.
• From those usages, you can then trace the calls to methods of IMyInterface.

4. Using Rider's Structure View:

Rider's Structure view (View - Tool Windows - Structure) can help you understand the class's members and how they relate to the interface. It provides a hierarchical view of the class, making it easier to spot interface implementations and usages.

5. Text Search (as a last resort):

While not as precise, you can use Rider's text search (CtrlShiftF) to search for the interface name or method names within the MyClass file. This can be useful for finding less obvious usages, but it might also return false positives.

Example Summary

In this example, to find where IMyInterface is used, you'd "Find Usages" on GetMessage in the IMyInterface definition. Rider would highlight the line string message _dependency.GetMessage(); within MyClass.
