Error to add local sql database with MS Visual Studio 2015

Question

I installed all Visual Studio 2015, SQL express 2014, and SQL Manager 2014. When I try to add new .mdf database by click [add new item] under [Project] in Visual Studio, it will pops up a message like the picture

However, when I try to create a local database by right click [add connections] in [Server Explore] section, it also pops up a message like the picture

In addition, my local sever configuration is like this

How can solve this problem. What am going to do is try to add local database to my application, so after I publish my application this database will store the information for user.
