Is there a tool to compile "selective" assemblies containing only certain types?

Say I have a large project contain开发者_如何学运维ing the types A through Z.

What if, for whatever reason, I want to package and distribute just type A to some client(s)?

Obviously I cannot just compile A into its own DLL unconditionally; it may depend on some other types in my project. But it's unlikely it depends on every type in my project.

What I'm envisioning is some tool that could examine A, identify its dependencies, and somehow compile a minimal DLL with only the types required for the type I want (A) and no more.

So for example if A depends on functionality provided by B and C, and B depends on D, but C and D have no additional dependencies (aside from possibly A, B, or each other), this tool would take A through D and compile just those types into a DLL for me to do with as I see fit.

Is such functionality available through Visual Studio? If not, is there some add-in or external tool capable of doing this? Incidentally, is what I'm asking about even reasonable, or do you feel that something like this would be a bad idea?

Obviously I could always do this manually; it just seems like that would be a lot of work (and if it's a bad idea to begin with, well, then just forget it).

This sounds like an ideal problem for a make file. I don't know how the .NET bit will play into it but for the classic C model you could do something like this:

clean :
    del *.obj

libA.lib : A.obj
    makelib *.obj

libB.lib : B.obj
    makelib *.obj

...

A.obj : B.obj C.obj
    compile A.cs

B.obj : C.obj D.obj
    compile B.cs

C.obj : 
    compile C.cs

D.obj : 
    compile D.cs

...

Run make clean A and you should get everything you need for A and nothing more.
