I created an assembly and installed it into the Global Assembly Cache.
(I can find that in my C:\windows\Assembly\ directory)

after that i designed a client application to test that global
assembly

what sud i do in the client application to access the classes in that
Global Assembly

i used

using SharedAssembly1; // this is my assembly name

i can access that only if i add a reference of this dll to my client
app.. (but i think this is not that actual way when we installed it in
GAC)

thanks
