Just created branda new MVC 4 project and instead of expected "hello world" got following error:

==================================================== Server Error in '/' Application. Configuration Error Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.

Parser Error Message: Default Role Provider could not be found.

Source Error:

Line 244: Line 245: Line 246: Line 247: Line 248:
