I need to fetch the source code from wsp in SharePoint 2010. I am having the wsp file and i can converted it to a caqb file and opened this zip and extracted it. so i got the DLL.
But how to see the ascx file's cs file - source code- within this wsp
Now you need to decompile the dll files using any of the tools available. I personally prefer JetBrains dotPeek, which is free for download from jetbrains web site.
