Global Assembly cache is for storing the assemblies designated to be shared by various applications.

I have created one class library project and added a function called Addition

As shown in the figure this function accepts 2 integer variables and return the sum of these 2 integers. This path of this project is D:\GACLibrary.

I have compiled the project and after compilation GACLibrary.dll will be made in the bin folder.

Step 1 → create the strong key

Go to command prompt
Go to the directory where the dll file is placed .In this case the path is d:\GacLibrary\GacLibrary\Bin\debug as shown in fig below

Write the following command on the command prompt

and press enter

This would generate a strong name key pair and store it in a file named as GACLibrary.snk

Step 2 → Associate strong name to the assembly

Right click on the project in the solution explorer and click properties
