I wanted to fix a bug in the html Editor Extender of the ACT, so I went to GitHub, downloaded a copy, made my change. But then I did not know how to make my asp.net project use it. I can't just copy the dll that is produced to the bin folder of my project, because I get this error:
Could not load file or assembly 'AjaxControlToolkit, Version=15.1.4.0, Culture=neutral, PublicKeyToken=28f01b0e84b6d53e' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
Its possible that the GAC has another version, or the web.config refers to an assembly that doesn't match, or maybe the manifest (where-ever that is) has to be changed.
Any help is appreciated.
