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.

What I have tried:

I have added it in Solution Explorer I have postgresql data sourcce option there then why it is not present here??

I'm not a user of Entity Framework, but maybe this answer will help:
c# - Postgresql and Entity Framework - Stack Overflow[^]

Could be that you need:
<provider invariantName="Npgsql" type="Npgsql.NpgsqlServices, EntityFramework5.Npgsql" />

I have added all dependencies through NuGet then it should automatically update my app.config file. But my question is little bit different. Why I am unable to see POstgreSQL provider name in Entity Data model Wizard..
Thank you....
