What is an Assembly in C#?

It is a set or group of types built to function in a coordinated way. Assembly in c# acts as a unit and functions in a logical way finally acting as .exe and .dll files. They are the building blocks of .NET applications.

To simplify the meaning, we can term it as a file generated automatically by the compiler on the compilation of every .NET application in a successful way.

They constitute basic or fundamental units of deployment, version control, reuse, activation scoping, and security permissions for .NET-based applications.

Basic Features of Assembly in C#

• It can be static (stored on disk in portable executable files) or dynamic (to disk after they have been executed).
• Static assemblies may incorporate such things as interfaces, classes, and resources like bitmaps, JPEG files, and other resource files.
• Dynamic assemblies can run directly from memory and may not be saved to disk before execution.
• Assemblies can be used with the use of development tools like Visual Studio that can create .dll or .exe files and the Windows SDK with modules from other development environments.
• Assemblies are of two types in .NET. They are: Single file containing all relevant information including Metadata and Manifest and Multi file constituting different .NET binaries or modules that are generated for larger applications. 

In Conclusion:

Assembly in c# provides the common language runtime. This helps or enables the programme with all the facts and information it needs to be aware of type implementations.
