Can't see SQL Server table data in Server Explorer Window

In my asp.net MVC application I created the database and then went to server explorer and I select one table and select open table data. I received the following error message.

"An incompatible SQL Server was detected"

Here is my connection string

<add name="YogaBandy" connectionString="Data Source=(localdb)\MSSQLLocalDB;AttachDbFilename=|DataDirectory|\YogaBandy.mdf;Initial Catalog=YogaBandy;Integrated Security=True" providerName="System.Data.SqlClient" />

I'm using VS 2013, asp.net mvc 5 and sql server express 12 I think...
