Update not working with ObjectContext

[Coder3333]

1. Description

I have a very simple query that uses the old ObjectContext, instead of DbContext, and it fails when I try to perform an Update.

2. Exception

Exception message:
System.AggregateException: One or more errors occurred. ---> System.AggregateException: One or more errors occurred. ---> System.Exception: Oops! A general error has occurred. Please report the issue including the stack trace to our support team: info@zzzprojects.com

Stack trace:

4. Any further technical details

I have traced the server, and no SQL is being executed.

Z.EntityFramework.Plus.EF6 5.1.31.0

Hello @Coder3333 ,

We didn't successfully implement it in our library.

However, we have a public extension method that could help you: GetOrCreateDbContext

Such as:

objectContext.GetOrCreateDbContext().Set<Customer>().Update(x => new Customer {Code = "zzz"});

Let me know if this workaround is working for you.

As you understand, this method returns a DbContext even if you are using purely an ObjectContext.

Best Regards,

Jon
