In this blog, I’m trying to explain the private and shared assembly and differences between them.
This type of assembly is used by a single application. It is stored in the application's directory or the applications sub-directory. There is no version constraint in a private assembly.
Shared Assembly or Public Assembly
A shared assembly has version constraint. It is stored in the Global Assembly Cache (GAC). GAC is a repository of shared assemblies maintained by the .NET runtime. It is located at C:\Windows\Assembly OR C:\Winnt\Assembly. The shared assemblies may be used by many applications. To make an assembly a shared assembly, it has to be strongly named. In order to share an assembly with many applications, it must have a strong name.
Differences between Private and Shared Assembly
- Private assembly can be used by only one application.
- Shared assembly can be used by multiple applications
- Private assembly will be stored in the specific application's directory or sub-directory.
- Shared assembly is stored in GAC (Global Assembly Cache).
- There is no other name for private assembly.
- Shared assembly is also termed as shared assembly
- Strong name is not required for private assembly.
- Strong name has to be created for shared assembly.
- Private assembly doesn't have any version constraint.
- Shared assembly should strictly enforce version constraint.
