.net core 在.NET Core 3.1 Nano Server Docker映像上安装.NET运行时

我有一个.NET Core 3.1控制台应用程序，它使用

Microsoft.NET.Sdk.WindowsDesktop

project Sdk，因为它引用了

System.Windows.Media.Media3D

中的

Geometry3D

我想在Windows Nano Server上的Docker容器中运行此操作，但在执行

Docker run

时收到以下错误：

It was not possible to find any compatible framework version
The framework 'Microsoft.WindowsDesktop.App', version '3.1.0' was not found.
  - No frameworks were found.

You can resolve the problem by installing the specified framework and/or SDK.

The specified framework can be found at:
  - https://aka.ms/dotnet-core-applaunch?framework=Microsoft.WindowsDesktop.App&framework_version=3.1.0&arch=x64&rid=win10-x64

如何安装所需的sdk和运行时？

这是我现有的Dockerfile：

FROM mcr.microsoft.com/dotnet/core/runtime:3.1-nanoserver-1903 AS base
WORKDIR /app

FROM mcr.microsoft.com/dotnet/core/sdk:3.1-nanoserver-1903 AS build
WORKDIR /src
COPY ["HelloWpfCore/HelloWpfCore.csproj", "HelloWpfCore/"]
RUN dotnet restore "HelloWpfCore/HelloWpfCore.csproj"
COPY . .
WORKDIR "/src/HelloWpfCore"
RUN dotnet build "HelloWpfCore.csproj" -c Release -o /app/build

FROM build AS publish
RUN dotnet publish "HelloWpfCore.csproj" -c Release -o /app/publish

FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "HelloWpfCore.dll"]

我找到了答案。我创建了一个映像，用于在Nano服务器基础映像上安装Windows桌面运行时

我将此推送到Docker Hub上的回购协议：

然后，我只是将此自定义图像用作示例应用程序的基础图像：
