I am upgrading my practice Entity Framework code to v4.1. In old version, I had my context class deriving from ObjectContext but with new release of EF 4.1, they have provided a good DbContext API.
I am basically trying to convert the code so that it works from Database First approach to Code First approach. Playing around with EF 4.1
In old code, I had something like
context.Connection.BeginTransaction(isolationLevel);
where the context Type was deriving from Obje开发者_C百科ctContext.
In v4.1 I haven't got access to Connection property from context. How can I do that?
It is in the DbContext and it should be public.
dbContext.Database.Connection.ConnectionString
also:
dbContext.Database.Connection.BeginTransaction(isolationLevel)
In the brave new .Net Core world, you can use:
using Microsoft.EntityFrameworkCore;
context.Database.GetDbConnection();
The new DBContext has
context.Database.Connection.BeginTransaction()
method with some overloads. Do a Goto Definition in Visual Studio to see the methods.
You can use something like
((IObjectContextAdapter)context).ObjectContext.Connection.BeginTransaction(isolationLevel);
