How to restrict access to my DLL

Is possible to restrict access to my .NET DLL library? My application has more EXE assemblies and I need share some code, but I don't want someone else could use that.

you can sign your code, and check the signature in the dll I guess. you can use a secret (that can easily engineered from disassemblly of your dll) between the exe and the dll

It depends on how much you care. A simple way is to make everything internal and then use friend assemblies to allow your assembly to call it.

Most things you would do can be defeated, but if someone wants to call, they will figure out a way to do it.

You could make all your APIs internal and expose the other assembly as a friend. This is by no means copy protection though, someone can still dissassemble your assembly.
