You can use the EntityFramework Reverse POCO Generator Visual Studio extension. As its documentation says:

Reverse engineers an existing database and generates EntityFramework Code First POCO classes, Configuration mappings and DbContext.

Also, you can use the Entity Framework Power Tools Visual Studio extension, which includes more functionalities, like generating diagrams of your data models.

To use EF PowerTools with Visual Studio 2015 do as explained in this post.

In addition to generate your POCO entities and database context you will have to enable the use of migrations with the Package Manager Console and to generate at least an initial migration for your database. You will get a migration Configuration class, and will need to configure a Database Initializer. This page explains the basics of these steps.
