I am stuck in the middle of a project. I am having an issue with adding the data source in "Entity Data Model Wizard"

Navigation Path:::::

Solution Explorer : Models(Folder): Add : New Item : ADO.NET Entity Data Model : EF Designer From Database : New Connection

Now here in "New Connection" I want to connect my postgresql database using Postgresql Datasource but I have only SQL Server datasource option there, Anybody know how to deal with this ERROR..??

Note: I have added Npgsql, entityframework5.Npgsql through NuGet.
