Entity Framework Core 不支持我需要在我的应用程序中使用的空间数据。

我可以在 .net 核心中使用 Entity Framework 6 吗？DatabaseContext如果是这样，我该如何注册Startup.cs？

Update

You can now use EF 6.3 with .NET Core 3.0:

https://devblogs.microsoft.com/dotnet/announcing-ef-core-3-0-and-ef-6-3-general-availability/#what-s-new-in-ef-6-3

Below is an excerpt. However, EF Core has come a long way these days and it's worth giving it another go before going back to something that's reaching end-of-life soon. Specifically for your issue, EF Core supports mapping to spatial data types using the NetTopologySuite spatial library since version 2.2.

What’s new in EF 6.3

  • Support for .NET Core 3.0

  • The EntityFramework package now targets .NET Standard 2.1 in addition to .NET Framework 4.x.

  • This means that EF 6.3 is cross-platform and supported on other operating systems besides Windows, like Linux and macOS.

  • The migrations commands have been rewritten to execute out of process and work with SDK-style projects.

  • Support for SQL Server HierarchyId.

  • Improved compatibility with Roslyn and NuGet PackageReference.

  • Added ef6.exe utility for enabling, adding, scripting, and applying migrations from assemblies. This replaces migrate.exe. There are certain limitations when using EF 6.3 in .NET Core. For example:

  • Data providers need to be also ported to .NET Core. We only ported the SQL Server provider, which is included in the EF 6.3 package.

  • Spatial support won’t be enabled with SQL Server because the spatial types aren’t enabled to work with .NET Core.

  • Note that this limitation applies to EF 6.3 but not to EF Core 3.0. The latter continues to support spatial using the NetTopologySuite library.

  • There’s currently no support for using the EF designer directly on .NET Core or .NET Standard projects.

Original Answer

It isn’t ready yet, but starting with .NET Core 3.0, you will be able to.

Similarly, EF6 will be updated to work on .NET Core 3.0, to provide a simple path forward for existing applications using EF6.

But there's also EF6, which we've already announced is going to be ported to work on .NET Core...

更新：是的，EF6 自 6.3 版以来一直是跨平台的。https://devblogs.microsoft.com/dotnet/announcing-ef-core-3-0-and-ef-6-3-general-availability/#what-s-new-in-ef-6-3


现在无效的原始答案：不，您不能直接使用，因为 EF6 不支持 .NET Core。但是，您可以创建另一个项目，该项目针对完整的 .NET 框架进行编译并将其用作参考。

MS实际上为此做了一个不错的教程： https ://docs.microsoft.com/en-us/aspnet/core/data/entity-framework-6#reference-full-framework-and-ef6-in-the- asp-net-core-项目

现在无效的原始答案：就像@Niko 所说，您不能直接使用，EF6但有一个允许它的叉子。

免责声明：我是实体框架经典项目的所有者

Entity Framework Classic 是一个 EF6 分支。它是您喜欢 EF6 的一切，但具有更好的性能、必备功能、.NET Core 支持等。

有一个包含几乎所有内容的免费社区版和一个包含附加功能的企业版。
