Issue with postgresql Views import in Entityframework

[SaurabhDeveloper-connect]

Issue with EntityFramework6.Npgsql for .net 4.8 framework.

I am trying to import views from postgres env, we are getting error of PrimaryKey not found in views, however primary keys are added in tables.

For the work around I added Views manually in .net edmx file-
In Context file- added reference
Added Entity file in *.tt
Added reference of Views in edmx at different places like store, mapping and entitySet.

It is compiling and not giving any error. However when I am running the solution it is throwing error-

System.InvalidOperationException
HResult=0x80131509
Message=The entity type vwuserlogin is not part of the model for the current context.

StackTrace:

at System.Data.Entity.Internal.Linq.InternalSet`1.get_Local()

'connectData.vwuserlogins.Local' threw an exception of type 'System.InvalidOperationException'

Npgsql version: -4.1.12
Entityframework.Npgsql- 6.4.3
PostgreSQL version: 14
Operating system: Windows

Thanks.

@SaurabhDeveloper-connect I'm really not sure we'll be able to help you here... For one thing, there's a lot of details missing from your report - always try to submit a minimal, runnable code sample so that the maintainer can reproduce your error and investigate it.

But beyond that, non-core EF6 has been archived for a long while, and I definitely don't have the knowledge to help you with it. Maybe someone in the community can.
