We need to back up the files in the production environment especially when we update our projects in this environment. There is not any problem to reach the files under IIS but we don’t have a chance to copy the dll files inside the GAC(Global Assembly Cache) because Windows lists these files in a different view. If you want to reach the dll files inside the GAC(Global Assembly Cache) directly, the command line that will be written on MS-DOS screen will help you.
regsvr32 –u C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\shfusion.dll
By this command, the assembly files inside the GAC are listed in normal view. After you back up the files, if you want to switch to old view you must use the same command without using –u parameter as given below;
regsvr32 C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\shfusion.dll
PS: Sometimes you can see that the files aren’t listed properly although you execute the second command. In this case, you can try to refresh the page or close and reopen the page.
