我有一个使用Microsoft.NET.Sdk.WindowsDesktop项目 SDK 的 .NET Core 3.1 控制台应用程序，因为它Geometry3D在System.Windows.Media.Media3D.

我想在 Windows Nano Server 上的 Docker 容器中运行它，但在执行时收到以下错误docker run：

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"]

我想到了。我创建了一个在 Nano Server 基础映像上安装 Windows 桌面运行时的映像。

# escape=`

# Installer image
FROM mcr.microsoft.com/windows/servercore:1909 AS installer

SHELL ["powershell", "-Command", "$ErrorActionPreference = 'Stop'; $ProgressPreference = 'SilentlyContinue';"]

# Retrieve .NET Core Runtime
# USER ContainerAdministrator
RUN $dotnet_version = '3.1.5'; `
    Invoke-WebRequest -OutFile dotnet-installer.exe https://download.visualstudio.microsoft.com/download/pr/86835fe4-93b5-4f4e-a7ad-c0b0532e407b/f4f2b1239f1203a05b9952028d54fc13/windowsdesktop-runtime-3.1.5-win-x64.exe; `
    $dotnet_sha512 = '5df17bd9fed94727ec5b151e1684bf9cdc6bfd3075f615ab546759ffca0679d23a35fcf7a8961ac014dd5a4ff0d22ef5f7434a072e23122d5c0415fcd4198831'; `
    if ((Get-FileHash dotnet-installer.exe -Algorithm sha512).Hash -ne $dotnet_sha512) { `
        Write-Host 'CHECKSUM VERIFICATION FAILED!'; `
        exit 1; `
    }; `
    `
    ./dotnet-installer.exe /S

# Runtime image 
FROM mcr.microsoft.com/windows/nanoserver:1909

ENV `
    # Enable detection of running in a container
    DOTNET_RUNNING_IN_CONTAINER=true

# In order to set system PATH, ContainerAdministrator must be used
USER ContainerAdministrator
RUN setx /M PATH "%PATH%;C:\Program Files\dotnet"
USER ContainerUser

COPY --from=installer ["/Program Files/dotnet", "/Program Files/dotnet"]

我将此推送到 Docker Hub 上的仓库：https ://hub.docker.com/repository/docker/tonysneed/dotnet-runtime-windowsdesktop

然后我简单地使用这个自定义图像作为我的示例应用程序的基础图像：https ://github.com/tonysneed/hello-netcore-wpf-nano
