Can't run .net core Web API using visual studio 2015

I'm getting the following an error in visual studio 2015 while running the asp.net core Web API project in my windows 7 64 bit machine.

The program '[15460] dotnet.exe' has exited with code -2147450749 (0x80008083).
The program '[16176] dotnet.exe' has exited with code -2147450749 (0x80008083).
The program '[15432] iisexpress.exe' has exited with code 0 (0x0).
The program '[10296] iisexpress.exe' has exited with code 0 (0x0).

Can anyone please help me to resolve this issue?
