Define Assembly in .NET.- An assembly is the primary unit of a .NET application.
- It includes an assembly manifest.
- Manifest describes the assembly.
- The .Net Framework keeps executable code or DLL in the form of assembly.
- The .Net Framework maintains multiple versions of the application in the system through assembly.
- The assemblies have MSIL code and manifest that contains metadata.
- The metadata contains version information of the assembly.
- Assemblies are the main building blocks.
- An assembly may be defined as a unit of deployment.
- A single assembly is a collection of types, and resources.
- The CLR does not understand any types that are outside assemblies.
- The CLR executes the code in assemblies as they contain MSIL code.
- They define type, version and security boundaries.
- Assemblies in .Net are a solution to the DLL hell problem as one can use different versions of the same assembly in different applications at the same time. What is a shared assembly?- An assembly is a partially compiled code library.
- In .NET framework, an assembly is a portable executable and can be an EXE (process assembly) or a DLL (library assembly).
- An assembly can consist of one or more files or modules in various languages.
- It is used in deployment, versioning and security.
- It is the standard for components developed with the Microsoft .NET.
- The .NET assemblies may or may not be executable, it means they might exist as the executable (.exe) file or dynamic link library file.
Shared assembly:
- This assembly is also called as strong named assemblies.
- These assemblies are copied to a single location .
- Shared assemblies are not copied in the private folders of each calling assembly.
- Each assembly has a four part name, including its face name, version, public key and culture information.
- It is stored in the Global Assembly Cache(GAC) with a strong name assigned to it.
- GAC contains a collection of shared assemblies.
