In my last post, I discussed, how to access internal class of one assembly in another assembly and that is easily achieved with the help of a C# feature called Friend Assemblies. It allows us to call the internal methods of another assembly. It is very much required at several occasions like the one I discussed in my last post, Unit Testing. It is often required to test the internal classes of the assembly in another project of Unit testing and It can be done easily via Friend Assembly.

But in some other scenarios Friend assemblies solution may not work. Like if you have two assemblies and one assembly accesses other assembly using Friend assembly. It’ll be fine as long as both assembly are compatible and shipped at same point of time. And if it does not happen on regular basis or in every release/update of assembly this may be hazardous.
To avoid it, we should implement it in another way. Here we declare the method as public but will limit to its accessibility to some specific assembly. It can be achieved by using LinkCommand with StrongNameIdentityPermission.
