Is it possible to use EF Core 6 in combination with a MongoDb?是否可以将 EF Core 6 与 MongoDb 结合使用？ From what I'v gathered online, I could only find answers from a few years ago that say that it's still not possible, but nothing that was published recently.从我在网上收集的内容来看，我只能找到几年前的答案，说这仍然不可能，但最近没有发表任何内容。 There is also better support for the Azure Cosmos Db which is also a NoSql database, so maybe I could use that to communicate with a MongoDb?对 Azure Cosmos Db 也有更好的支持，它也是一个 NoSql 数据库，所以也许我可以用它与 MongoDb 通信？

If it's still not possible, what other approach should I use?如果仍然不可能，我应该使用什么其他方法？

While there is no MongoDb provider for EF (to my disappointment), there is, at least, a provider for CosmosDb, Azure's fully managed NoSQL solution.虽然 EF 没有 MongoDb 提供程序（令我失望），但至少有一个 CosmosDb 提供程序，Azure 的完全托管 NoSQL 解决方案。

Once can't help but wonder if it's intentional -- but I imagine the unit-of-work pattern with transaction rollback as well as Migrations support. Once 忍不住想知道这是否是故意的——但我想像具有事务回滚和迁移支持的工作单元模式。

In the mean time, you can consider something along the lines of the repository pattern so that your data access does not depend on your infrastructure.同时，您可以考虑一些类似于存储库模式的东西，以便您的数据访问不依赖于您的基础设施。

There is an open issue on MongoDB's site about providing an officially supported EF Core provider.

There is no official MongoDb provider implementation for EF core at this time, I did not see any mention of MongoDb in the .net core 7 (the next version) roadmap as of now. EF 核心目前没有官方的 MongoDb 提供程序实现，我没有看到 .net 核心 7（下一个版本）路线图中提到 MongoDb。

I quickly googled a bit but could not find a recent version of a MongoDb provider.我快速搜索了一下，但找不到 MongoDb 提供程序的最新版本。

Msdn docs also do not use EF core: https://docs.microsoft.com/en-us/aspnet/core/tutorials/first-mongo-app?view=aspnetcore-6.0&tabs=visual-studio Msdn 文档也不使用 EF 核心： https://docs.microsoft.com/en-us/aspnet/core/tutorials/first-mongo-app?view=aspnetcore-6.0&tabs=visual-studio
