1. What is an assembly?

Ans. Assemblies are the smallest units of versioning and deployment in .Net application.Assemblies are also building blocks for programs such as Web Services,Windows Services,Service Components and .Net Remoting Applications.

Here are some general Concepts of an Assembly.

An Assembly is a logical unit of code

Assembly physically exist as DLLs or EXEs

One assembly can contain one or more files

The constituent files can include any file types like image files, text files etc. along with DLLs or EXEs

When you compile your source code by default the exe/dll generated is actually an assembly

Unless your code is bundled as assembly it can not be used in any other application

When you talk about version of a component you are actually talking about version of the assembly to which the component belongs.

Every assembly file contains information about itself. This information is called as Assembly Manifest.

2.What is Satellite assembly?

Ans. A .NET Framework assembly containing resources specific to a given language. Using satellite assemblies, you can place the resources for different languages in different assemblies, and the correct assembly is loaded into memory only if the user elects to view the application in that language.

3.What is MSIL?

Ans. Microsoft Intermediate Language (MSIL) is a platform independent language that gets compiled into platform dependent executable file or dynamic link library.It means .NET Compiler can generate code written using any supported languages and finally convert it to the machine code depending on the target machine.

4.What is CLR?

Ans. CLR is Common Language Runtime that provides multi-language execution environment for .NET.It executes the MSIL code to the native machine code.It helps us to use classes which is created in another .NET language.For eg. You can use a class created using vb in c#.

5.What is CTS?

Ans. CTS is the .NET Framework specification for defining, declaring, and managing types in .NET languages for the Common Language Runtime (CLR). All .NET components must comply with the CTS specification.
