Install an assembly into the Global Assembly Cache without gacutil

When we need to register an assembly in the GAC, generally we use the Global Assembly Cache tool (Gacutil.exe) with this command gacutil -i <assembly name>

But Gacutil.exe is only for development purposes and should not be used to install production assemblies into the global assembly cache.

One of the solutions is to use PowerShell to install a DLL into the GAC (Global Assembly Cache) by doing the following

[Reflection.Assembly]::LoadWithPartialName("System.EnterpriseServices") | Out-Null

[System.EnterpriseServices.Internal.Publish] $publish = new-object System.EnterpriseServices.Internal.Publish

$publish.GacInstall(<<FullFilePathToTheDll>>)

This has to do very little with native PowerShell but rather with instantiating and using .NET libraries from PowerShell

After that you need to do an IISRESET in the server
