I found very nice solution  Microsoft released a beta version of Entity Framework Power Tools  Entity Framework Power Tools Beta 2  There you can generate POCO classes  derived DbContext and Code First mapping for an existing database in some clicks  It is very nice   After installation some context menu options would be added to your Visual Studio   Right-click on a C  project  Choose Entity Framework-  Reverse Engineer Code First  Generates POCO classes  derived DbContext and Code First mapping for an existing database      Then choose your database and click OK  That s all  It is very easy
