Hello @Mohamed Hassan Anver,

I think that the tutorial is for EF 6 that is designed for .NET Framework. And MS is not promoting more EF Framework, right now, MS has EF core as goal (check this: https://docs.microsoft.com/es-es/ef/efcore-and-ef6/ ) and is the right EF to go in my opinion.

However IRIS is not supporting EF Core https://community.intersystems.com/post/how-can-i-use-iris-net-core-entity-framework. :-( 

Any thought @Bob Kuszewski ?

There is a way (right now) of create automatically a BO and related Messages to consume a REST API described in Swagger? I am thinking in something like the WSDL Wizard in Studio but using Swagger. If not I think this is a very good idea for this contest.

I see.

So I guess I should use EnsLib.HL7.SchemaDocument class https://docs.intersystems.com/irisforhealthlatest/csp/documatic/%25CSP.Documatic.cls?APP=1&LIBRARY=ENSLIB&CLASSNAME=EnsLib.HL7.SchemaDocument but can't find an example of how import/export programatically.

In response to @Evgeny Shvarov I am talking about Custom HL7 Schemas (https://docs.intersystems.com/irisforhealthlatest/csp/docbook/Doc.View.cls?KEY=EHL72_tools#EHL72_customhl7schema_editor) in IRIS for Health. Use custom schemas is something very usual and I think that to include this import feature in Installer could be very useful... I'll try to make it works and if I am success I'll post the how-to :-D
