You should take a look at the internals of metadata... http://msdn.microsoft.com/en-us/library/8dkk3ek4.aspx If a token is on 32 bits and 8 of them are used for the type, then the rest 24 are used for identifying the type/method/a.s.o. Therefore, a dll can have 2^24 - 1 types = 16.777.215. I did a test once to dynamically create types in an assembly but it was not able to finish the job... :) App: http://cid-a7ab3515d88063ad.office.live.com/self.aspx/.Public/AssemblyBuilder.exe Other resources: http://eusebium.blogspot.com/2009/10/how-many-classes-can-single-net-dll.html
