[AssemblyKeyFile] C# with Example

Whenever we want our assembly to install in GAC then it is must to have a strong name. For strong naming 
assembly we have to create a public key. To generate the .snk file. 
To create a strong name key file 
1. Developers command prompt for VS2015 (with administrator Access) 
2. At the command prompt, type cd C:\Directory_Name and press ENTER. 
3. At the command prompt, type sn -k KeyFileName.snk, and then press ENTER. 
once the keyFileName.snk is created at specified directory then give refernce in your project . give 
AssemblyKeyFileAttribute attribute the path to snk file to generate the key when we build our class library. 
Properties -> AssemblyInfo.cs 
[assembly: AssemblyKeyFile(@"c:\Directory_Name\KeyFileName.snk")] 
Thi will create a strong name assembly after build. After creating your strong name assembly you can then install it 
in GAC 
Happy Coding :)
