Where is gacutil.exe in Windows 10?

I had to use the Microsoft Visual Studio 2015 Developer Command Prompt.

Unfortunately, Microsoft KB's are outdated and they usually give the wrong answers.

Go to Start -> Visual Studio 2015 -> Developer Command Prompt for VS2015

If you want find gacutil location then Follow this:

1. Go to Start menu.
2. A-search and find Developer Command Prompt
   or
   B-find and open Visual Studio 201_(2,3,5,7) Folder

3. click Developer Command Prompt for vs201(2,3,5,7)

4. Type and enter:( where gacutil )

5. "Developer Command Prompt" will be return location of gacutil.exe

But if you want cache dll , location of gacutil not necessary, Just run "Developer Command Prompt" and type : gacutil /i "dll_path"
