"Scanning for New and Updated MEF Components"

I can successfully reproduce the problem as I see fit. Below are my steps: Environment: Windows 10 Professional 64bit

  • Run vs_community_ENU.exe to install
  • Choose Microsoft website and developer tools
  • Let me do the installation
  • Open it for the first time, I see an ASP.NET web application
  • Close Visual Studio
  • Open it a second time, it will show some update: "Scanning new and updated MEF components ..." and two or three more undated
  • New project does not show asp.net web application along with other templates for a long time

How can I fix this problem? I uninstalled and reinstalled it 5 times already, and the same thing will happen again. I even installed VS2015.1.exe, but nothing happened

I have found the answer. If I run the “Blend for visual studio” shortcut and then in a new project, there are no asp.net templates along with others. But if I choose the standard "Visual Studio 2015", then there will be those templates ... I’m glad to find the answer, because I always delete and reinstall every time I accidentally close the visual studio 2015 community
