EF Core: Use Linked Server to Oracle database issue

问题

In another question, I need to use ASPNET BoilerPlate (EF Core template) with the Oracle database but it does not support so far. So I tried to use SQL Server with Linked Server to Oracle database.

What I have tried:

• Create Linked Server named "LinkedOracle" from SqlServer to Oracle database

• Create a SqlServer database named "FakeOracleDb" and create Views to LinkedOracle tables by:

  CREATE VIEW CUSTOMER AS SELECT * FROM LinkedOracle..MYUSER.CUSTOMER

• Now I have a fake SQL Server database that mapped from my Oracle Database (1 View = 1 table in Oracle). I also can select, update,.. in this View. My Customer entity is mapped to this View

• Change connection string to FakeOracleDb, the data is loaded ok, but when I tried to update the value, I faced the error as below:

Cannot start a transaction for OLE DB provider "OraOLEDB.Oracle" for linked server "LinkedOracle"

Could anyone gives me some advice, please

Update 1:

I have tried to open a transaction and run the update statement in SSMS. It worked after I run SET XACT_ABORT ON, so how can I set this value in EF?
