Go to Implementation

Last modified: 23 September 2024

This command helps you find actual implementations of types and members — in other words, to locate the source code they execute. For example, from a base type or member, you can jump to any of its end implementations bypassing intermediate steps in the inheritance chain; from a usage of an interface member, you can get to all places where the member is implemented.

The command is available on:

  • usages of types and members: it will list all places where they are implemented;

  • type declarations: it will list all derived types that implement their members, if any;

  • declarations of abstract or interface members that don't have implementation bodies: it will list all inheritors that have implementations.

It is not available on member declarations with an implementation body, including virtual members and default interface methods. Use Go to Derived Symbols to check inheritors of such members.

You can invoke this command from the Solution Explorer, Structure window, and other tool windows. If necessary, you can navigate in the opposite direction with the Go to Base Symbols command.

Here is an example of how Go to Implementation bypasses intermediate steps. Suppose that the IDocument interface has the following inheritors:

JetBrains Rider: Go to implementation. Hierarchy

When you invoke the Go to Implementation upon the declaration or a usage of the IDocument, JetBrains Rider shows only two inheritors:

JetBrains Rider: Go to implementation. Drop-down list

That is because other classes are abstract and do not contain implementation of the IDocument.
