在 EF Core 中使用 IsolationLevel 开始事务 [英] BeginTransaction with IsolationLevel in EF Core

问题描述

我正在尝试重写旧库以使用 EntityFramework Core，但我不知道如何以特定的隔离级别开始事务.

以前我能够做这样的事情:

DbContext.Database.BeginTransaction(IsolationLevel.Snapshot);

EntityFramework 核心中的替代实现是什么?

解决方案

EF Core 代码完全一样.

DbContext.Database.BeginTransaction(IsolationLevel.Snapshot);

唯一的区别是在 EF Core 中 具有隔离级别的方法(与许多其他方法一样)是一种扩展方法，定义在RelationalDatabaseFacadeExtensions 类，重要的是，位于 Microsoft.EntityFrameworkCore.Relational 程序集.

因此，如果您有 using Microsoft.EntityFrameworkCore; 并且没有看到它，请添加对 Microsoft.EntityFrameworkCore.Relational.dll 程序集/包的引用.>

I'm trying to rewrite old library to use EntityFramework Core and I can't figure out how to begin transaction with specific isolation level.

Previously I was able to do something like this:

DbContext.Database.BeginTransaction(IsolationLevel.Snapshot);

What is alternative implementation in the EntityFramework Core?

解决方案

The EF Core code is exactly the same.

DbContext.Database.BeginTransaction(IsolationLevel.Snapshot);

The only difference is that in EF Core the method with isolation level (as many others) is an extension method, defined in RelationalDatabaseFacadeExtensions class, and importantly, located in Microsoft.EntityFrameworkCore.Relational assembly.

So if you have using Microsoft.EntityFrameworkCore; and don't see it, add reference to the Microsoft.EntityFrameworkCore.Relational.dll assembly / package.
