  1. Global Assembly Cache (GAC)

  2. What is GAC • Repository containing all the assemblies of CLR • Machine wide • Assemblies shared by several applications • Where CLR is installed • C:\Windows\Microsoft.NET\assembly\GAC_MSIL

  3. Why we have to use GAC • Adding again and again assembly in different project • Shared location • File security • Side by side versioning (under consideration) • Additional search location

  4. How to install an assembly in GAC • Install by using the gacutil.exe tool • Recommended for developers • Install by using GUI interface of Windows installer

  5. How to make an assembly(.dll) • Create a library project in Visual studio • Add some functions • To sign an assembly with a strong name • public/private key pair • Use this command to make a key • sn -k <keyname>.snk • It creates a key pair file “keyname.sn”

  6. How to make an assembly(.dll) cont… • Put the key file in library project

  7. How to install an assembly(.dll) Method -1 • Open Visual Studio Command Prompt • Use this command to register assembly • gacutil.exe –i myassembly.dll • It creates the folder with assembly • C:\Windows\Microsoft.NET\assembly\GAC_MSIL

  8. How to install an assembly(.dll) Method -2 • Create a new setup project in same solution • Drag the assembly to the GAC folder • Build the setup project and install it • It creates the folder with assembly • C:\Windows\Microsoft.NET\assembly\GAC_MSIL

  9. How to register an assembly(.dll) cont… • Open registry and go to this path • Create a registry key with assembly location • For 32 bit • [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\VersionMinimum\AssemblyFoldersEx\MyAssemblies]@="AssemblyLocation“ • [HKEY_CURRENT_USER\SOFTWARE\Microsoft\.NETFramework\VersionMinimum\AssemblyFoldersEx\MyAssemblies]@="AssemblyLocation"

  10. How to register an assembly(.dll) cont… • For 64 bit operating system • [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\VersionMinimum\AssemblyFoldersEx\MyAssemblies]@="AssemblyLocation" • [HKEY_CURRENT_USER\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\VersionMinimum\AssemblyFoldersEx\MyAssemblies]@="AssemblyLocation“

  11. Use assembly in Visual Studio • Assembly is created under .NET column • Just right “using assembly name;” and enjoy 
