How to fix when new connection dialog fails in Visual Studio 2015

Last updated at Posted at 2017-05-05

  • Visual studio 2015
    • Close visual studio
    • eventvwr
      • check if any devenv error(s) in Application like
      • The data source '{7931728a-ebfb-4677-ad6b-995e29aa15c2}' specifies no supporting providers or a set that are not registered.
    • regedit
    • HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\14.0_Config\DataProviders\
    • Delete the key(s) that referred to the faulty data provider above
      • eg. npgsql

  • npgsql uninstaller leaves the registry information which causes this error... :cry:
