SQL Network Interfaces, error:50-a Local Database Runtime error has occurred. Cannot create an automatic instance.

Today in the VS2013 with the LocalDB to adjust the database error, on the internet also found many scenarios, such as uninstalling SQL Server LocalDB program, re-create the instance, etc. did not solve my problem, also re-modify and repair VS, the problem persists, After careful study, we found a solution:

1. First issue (note: I here is localdb V11.0 cannot use):

Microsoft Visual Studio--------------------------- - a Local Database Runtime error has occurred. Cannot create an automatic instance. For more information about errors, see the Windows application event log. )--------------------------- determine    ---------------------------

2. Solution:

A. View Loacldb version
　　SQLLOCALDB Delete v11.0
If the display is 12.00 you need to create a v12.0 instance
B. Delete the original v11.0 instance from the command prompt
  sqllocaldb Delete v11.0
　　C. Creating a new instance
SQLLOCALDB Create v11.0
　 use sqllocaldb Create v12.0 If the computer does not support this version or cannot be used for this automatic instance.  
The reason is that the LocalDB version is high, and the instance must change.
D. Another way is to re-install the localdb.
