1) Private - Assembly available only to clients in the same 
directory.
2) Shared - Assemblies in GAC
3) Satelite - Assembly in the specific directory of the 
locale.

There are two types of assemblies are there in .net. They are,
1. Private Assemblies and
2. Public/Shared Assemblies.
Private Assembly:- can be accessed only by single application in a system. It is stored in the application's directory .
Public Assembly-can be accessed by multiple applications in a system. This is about installing the assembly in GAC (global assembly cache).GAC contains a collection of shared assemblies.Assembly file format(.exe or .dll)

the question is meaningless because, the concept of "asp.net framework" does not exist

Assemblies

An assembly is a collection of types and resources that forms a logical unit of functionality. All types in the .NET Framework must exist in assemblies; the common language runtime does not support types outside of assemblies. Each time you create a Microsoft Windows® Application, Windows Service, Class Library, or other application with Visual Basic .NET, you're building a single assembly. Each assembly is stored as an .exe or .dll file.

Note   Although it's technically possible to create assemblies that span multiple files, you're not likely to use this technology in most situations.

The .NET Framework uses assemblies as the fundamental unit for several purposes:

• Security
• Type Identity
• Reference Scope
• Versioning
• Deployment
