为什么 dotnet 5 docker 容器在运行时失败？

Question

我有一个 dotnet5 控制台应用程序，它位于解决方案内，并且依赖于其他同级项目。我使用 Visual Studio 工具创建 Docker 文件，这是 Docker 文件：

FROM mcr.microsoft.com/dotnet/runtime:5.0-buster-slim AS base
WORKDIR /app

FROM mcr.microsoft.com/dotnet/sdk:5.0-buster-slim AS build
WORKDIR /src
COPY ["src/MyProject/MyProject.Launcher/MyProject.Launcher.csproj", "src/MyProject/MyProject.Launcher/"]
COPY ["src/MyProject/MyProject.DataAccess/MyProject.DataAcess.csproj", "src/MyProject/MyProject.DataAccess/"]
COPY ["src/MyProject/MyProject.Service/MyProject.Service.csproj", "src/MyProject/MyProject.Service/]
COPY ["src/Domain/MyProject.Domain.Model/MyProject.Domain.Model.csproj", "src/Domain/MyProject.Domain.Model/"]
RUN dotnet restore "src/MyProject/MyProject.Launcher/MyProject.Launcher.csproj"
COPY . .
WORKDIR "/src/src/MyProject/MyProject.Launcher"
RUN dotnet build "MyProject.Launcher.csproj" -c Release -o /app/build

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

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

构建图像正常，它通常添加到我的本地图像注册表中，但是当我尝试运行此图像并创建容器时，我收到此错误：

无法找到任何兼容的框架版本 找不到框架“Microsoft.AspNetCore.App”版本“5.0.0”。

• 没有找到框架。

您可以通过安装指定的框架和/或SDK来解决该问题。
