How to put Assembly In GAC

How to put Assembly In GAC


In this, post we will see how to put assembly into GAC or Global assembly cache. Here we will also see how to use
GACUTIL and .net command prompts

To add assembly into GAC we need sign the assembly with strong name.

You can get the Key pair by opening .Net command prompt and execute SN -k c:\xxxxx.snk

e.g.

Setting environment for using Microsoft Visual Studio 2005 x64 cross tools.

c:\Program Files\Microsoft Visual Studio 8\VC>sn -k c:\xxx.snk

Microsoft (R) .NET Framework Strong Name Utility  Version 2.0.50727.42
Copyright (c) Microsoft Corporation.  All rights reserved.

Key pair written to c:\xxx.snk

c:\Program Files\Microsoft Visual Studio 8\VC>



Now, copy the file xxx.snk generated by tool and paste it into your class library project.

open the assemblyinfo file give the path of newly created strongname keypair as shown in below example.
Compile the project. Now, your assembly is ready to get into GAC.



E.g.
Open assemblyinfo

add below line

[assembly: AssemblyKeyFile("xxx.snk")]


Save your assemblyinfo.cs file.

Compile the project.

Now, we will register assembly in gac.

Open your .Net command prompt

Use GACUtil -i to install the assembly into gac

c:\Program Files\Microsoft Visual Studio 8\VC>gacutil -i path_Of_your_signed_assembly.

You can find the assembly under Debug or Release folder of your BIN folder.

Now, your all applications can refer this shared assembly.

You can also browse GAC location using technique shown here: http://www.revenmerchantservices.com/ajax/systemwebextensions.html
