Partial classes in separate dlls

Question

Is it possible to have two parts (same namespace, same class name) to a partial class in separate DLLs?

Answer 1

No. Partial classes are a purely language feature. When an assembly is compiled, the files are combined to create the type. It isn't possible to spread the files out into different assemblies.

Depending on what you want to do, though, you might be able to use extension methods to accomplish what you need.
