即使我使用的是 .Net Core 3.1，我也可以更新到 .Net 5 NuGet 包吗? [英] Can I update to .Net 5 NuGet packages even if I'm using .Net Core 3.1?

问题描述

我正在寻找有关我的项目库的一些 NuGet 更新.我看到有很多 Microsoft 库更新到 v5.0.0.

I was looking for some NuGet updates about my project libraries. I see that there are a lot of Microsoft libraries update to v5.0.0.

根据我的知识，我认为这些是 .Net 5.0 发布的新依赖项，我不确定我是否可以使用 .Net Core 3.1 项目将这些库更新到最新版本.

Based on my knowledge I think these are new dependencies released with .Net 5.0 and I'm not sure that I can update these libraries to latest version using .Net Core 3.1 project.

即使我正在使用/构建 .Net Core 3.1 项目，我也可以更新到 v5.0.0 库吗?

Can I update to v5.0.0 libraries even if I'm using/building a .Net Core 3.1 project?

推荐答案

遗憾的是，您无法将这些最新的 Nuget 包中的许多更新到 5.0.原因是最新的 Nuget 包版本主要是为 .NET 5 编写的，而且通常 Nuget 包管理器甚至会阻止您安装它们，因为 API 存在差异.话虽如此，可能有几个地方允许安装，但如果您打算将应用程序保留在 .NET Core 3.1 上，我不会推荐它.它很可能会导致一些难以调试的不一致.谨慎操作，或将您的项目升级到 .NET 5.

Unfortunately, you cannot update many of these newest Nuget packages to 5.0. The reason being is that the newest Nuget package versions are written primarily for .NET 5, and often times Nuget Package Manager will even prevent you from installing them since there are differences in the APIs. With that said, there may be a few spots where it will allow the installation, but I wouldn't recommend it if you plan to keep the application on .NET Core 3.1. Most likely it could cause some inconsistencies that would be hard to debug. Proceed with caution, or upgrade your projects to .NET 5.
