Are C# delegates thread-safe?

Question

If you have a class instance with a delegate member variable and multiple threads invoke that delegate (assume it points to a long-running method), is there any contention i

Answer 1

Directly from the documentation of MulticastDelegate:

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.

The Delegate class contains the same information, so there you have it.
