Go to the bin folder of your project, delete all DLL files from there and then do Clean + Rebuild.

  • @osama_1200 Go to the Visual Studio, right-click on your Project name in the Solution Explorer, click the "Open Folder in File Explorer": http://take.ms/8ztQe Then go to the `bin` folder and manually delete all .dll files from there. After that come back to the Visual Studio, press Build - Clean, wait until it finishes, press Build - Rebuild. – Ivan Yurchenko Jun 27 '16 at 11:23
  • But friend i am using signal r in web site. I am not using project. This is a problem. When i will remove all dll from bin folder the web site will not build. – osama_1200 Jun 27 '16 at 11:36
  • Hm, I'm not sure you can fix this problem without having access to the project's source files. It looks like the global.asax is referencing to some obsolete DLLs. – Ivan Yurchenko Jun 27 '16 at 11:55
  • Try to delete all DLLs, then try to rebuild your web site, it will fail, then add back only those DLLs that are needed. – Ivan Yurchenko Jun 27 '16 at 11:58
