An assembly is a file that is automatically generated by 
the compiler upon successful compilation of every .NET 
application. It can be either a Dynamic Link Library or an 
executable file.
ASSEMBLIES ARE THE BUILDING OF DOTNET 
FRAMEWORK ,FUNDAMENTAL UNIT OF DEPLOYMENT ,VERSON 
CONTROL,REUSE, ACTIVATION SCOPING AND SECURITY PERMISSION
Diffrent Types of Assemblies:
1.PRIVATE
2.SHARED/PUBLIC
3.SATELLITE 
4.DYNAMIC
5.SINGLE FILE ASSEMBLY
6.MULTYFILE ASSEMBLY
Fratures of Assembles:
1.Assemblies are self_describing.
2.Version dependencies are recorded inside manifest.
3.Assembliles can be loded side by side.
4.Applilcation isolation is endured using application 
domains.
5.Installation can be as easy as copying the files that 
belong to an assemly.
6.Assemblies can be shared or private.

assembly is the logical code of data,and self deployment unit,
in physical it exist either .dll or .exe,
it contains four major parts:
1. Menifest- additional information of regarding to assembly
2. Type metadata:-Data about data or structure of classes
3. MSIL code:- containing business logics
4. Set of Resource: information or resource of other assembly

Assembly's are major building blocks of .net which is
generated by the language compiler.
Assemblies contains MSIL code,metadata,manifest,resource
information.
 assemblies can be a .dll or .exe files
 .dll assembly is called as library assemblies.
 .exe assembly is called as process assemblies.

asembly is nothing but .dll or .exe files

Its versioning deployment unit. it consists of assebly 
manifest,Metadata.

It is the smallest runtime unit

assembly is set of resources and types,along with 
metadata.About these resources and types it deploye as a 
single unit.It contains 1.Metadata
                        2.manifast
                        3.MSIL
                        4.Type /Security information.
                        5.Resources

assembly is the standard for components develoment with the 
ms.dotnet.assemblies may exists or may not exists.
all these assemblies consists defination of 
types ,versioning information of the 
types,metadata,manifest.

Assembly will generated for the project when it complies.
Each project have assembly either in .dll or .EXE format


Assembly file contains the IL, metadata , manifest(
information about the assembly version and other related
informations)

there are two types single file and multifile.
in multifile all (metadata, manifest, IL) in separate files.
while in single file all( IL, Manifest, Metadata) are in one
file.

assebly is a single deployment unit that contains all the
informations like dll and exe and MSIL
code,metadata,manifest,resource
information.
