.NET Forum / Windows Forms / WinForm General / January 2005Adding/Updating assemblies in GAC during runtime and not during Se
Is there an API or suggested technique by which I can add/update assemblies to the GAC during the runtime of my application instead of exclusively during the Setup of the application. I would like to be able to update some libraries without having to completely reinstall the application.  SignatureMichael Hockstein The API for the GAC is named "Fusion" and initially was not documented. Now you can see: DOC: Global Assembly Cache (GAC) APIs Are Not Documented in the .NET Framework Software Development Kit (SDK) Documentation http://support.microsoft.com/default.aspx?scid=kb;en-us;317540 Maybe an easier way is to use gacutil.exe -i <myassembly> from code.

I guess, I need to continue to look at the problem. wr > The API for the GAC is named "Fusion" and initially was not documented.

I'd be willing to try to run gacutil.exe from code. I assume that this will only work if the assemblies are not currently being used/loaded. In VB, how does one start an .exe from code(including use of command line switches), assuming the .exe is in the application folder?

Hi Michael, Based on my understanding, you want to know how to use the Gacutil.exe to install an assembly into the GAC through code. Does your "VB" mean VB.net? In .Net, we may use System.Diagnostics.Process.Start method to run Gacutil.exe and install an assembly into the GAC. For more information about the usage of Gacutil.exe, please refer to: "Global Assembly Cache Tool (Gacutil.exe)" http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cptools/htm l/cpgrfglobalassemblycacheutilitygacutilexe.asp If I misunderstand you, please feel free to tell me, thanks.

Yes, I'm in .NET. I will look at System.Diagnostics.Process.Start to run gacutil.exe from within my code. Thanks. I assume that 2 assemblies can have the same exact name and differ only by version number. I'll have to be careful with the gacutil and use fully qualified names when making changes to the GAC.

Hi Michael, Yes, we can only install strong-named assembly into the GAC. Anyway, if you need any further help, please feel free to tell me, I will help you.
