C# Language [InternalsVisibleTo]


Example

If you want to make internal classes or functions of an assembly accessable from another assembly you declare this by InternalsVisibleTo and the assembly name that is allowed to access.

In this example code in the assembly MyAssembly.UnitTests is allowed to call internal elements from MyAssembly.

[assembly: InternalsVisibleTo("MyAssembly.UnitTests")]

This is especially useful for unit testing to prevent unnecessary public declarations.
