asp.net-core - 未找到 IEndpointRouteBuilder 接口(interface)

Question

我有

NuGet Microsoft.AspNetCore.Http.Abstractions
NuGet Microsoft.AspNetCore.Routing

并使用命名空间

using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Routing;

我想构建这样的东西，但它似乎不知道 IEndpointConventionBuilder 也不 IEndpointRouteBuilder 并且拒绝编译。

public static class EndpointRouteBuilderExtensions
{
    public static IEndpointConventionBuilder MapServiceEndpoints(this IEndpointRouteBuilder endpoints)
    {

       //some code
    }
}

我错过了什么……？

如果要创建 ASP.NET Core 库，则需要包含 FrameworkReference在项目文件中如下:

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <TargetFramework>netcoreapp3.0</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <FrameworkReference Include="Microsoft.AspNetCore.App" />
  </ItemGroup>

</Project>
