This is my Database:

But when I followed the Entity Data Model Wizard I get the following error:

It seems that it's not supported by Visual Studio 2013. Any suggestion would be appreciated.

Thanks in advance.

I wrote the "Simple" DDEX provider, and it is only meant for running the EDMX Wizard in order to create a EDMX or Code First from Database model. (That is why it is called simple). So it does not support working with DataSets and DataAdapters. In addition you should not be using DataSet with SQL Server Compact due to the memory overhead. Use SqlCeResult set if possible: https://msdn.microsoft.com/library/bb219485.aspx
