我想知道为什么微软不在他们的产品上使用实体框架，比如服务总线、工作流管理器和 BizTalk 等等？
既然他们正在推动 .NET 社区使用它，为什么他们不启动该计划并向我们展示作为 .NET 堆栈开发人员如何使用 EF 最佳实践来实施企业项目的最佳实践？
这是否与自 EF 发布以来人们谈论的性能问题有关？

EF has come a long way since early versions of ORM. I have used in some very large projects and haven't had any significant performance issues. That said, products that you have mentioned have been there before EF came into existence so they may have some form of ORM which could have been build and maintained internally. If you are looking for some good pattern and practices please checkout some articles written by Julie Lerman.
