C# 升级到ASP.NET Core 5.0时Microsoft.EntityFrameworkCore.Relational的版本冲突

将项目从ASP.NET Core 3.1迁移到5.0后，我遇到了以下问题：

检测到的错误NU1107版本冲突 Microsoft.EntityFrameworkCore.Relational

直接将Microsoft.EntityFrameworkCore.Relational 5.0.0安装/引用到project Alpha.Web.App以解决此问题

Alpha.Web.App-> Microsoft.EntityFrameworkCore.Tools 5.0.0-> Microsoft.EntityFrameworkCore.Design 5.0.0-> Microsoft.EntityFrameworkCore.Relational（>=5.0.0）

Alpha.Web.App-> Pomelo.EntityFrameworkCore.MySql 3.2.4-> Microsoft.EntityFrameworkCore.Relational（>=3.1.8&&< 5.0.0）

E:\Projects\Alpha\Alpha.Web.App\Alpha.Web.App.csproj 1

我怎样才能解决它

Alpha.Web.App.csproj:

我已经删除了

Pomelo.EntityFrameworkCore.MySql

，现在它运行良好。 目前没有适用于.NET 5的兼容Pomelo软件包：

---

只需安装一个更新的兼容Pomelo软件包

---

Pomelo.EntityFrameworkCore.MySql（v5.0.0）

实际上与

Microsoft.EntityFrameworkCore.Relational（v5.0.x）

已将实体框架核心升级到最新版本吗？是的，我已升级。你可以看到。我已经删除了Pomelo.EntityFrameworkCore.MySql，现在它运行良好。目前还没有兼容的Pomelo包。net5.0将其作为一个答案发布，人们正在测试它，他们可能会来到这篇文章。
