我正在使用Visual Studio 2022在Windows 10上工作，并试图创建一个简单的ASP.NET Core Web App（.net 7.0）并将其放入Docker映像中。这个docker镜像应该部署到armv71（ARM32）设备上（通过tar archive）。当启动“Build Docker Image”时，它会失败，并出现以下错误：

ENTRYPOINT ["dotnet", "MyPlcDockerWebApp.dll"]我做错了什么？我已经尝试了不同的手臂基础图像，但它没有帮助。
在我的Windows机器上，当我使用www.example.com作为基础映像并使用www.example.com作为构建时，它工作正常（Docker容器获得构建并启动）mcr.microsoft.com/dotnet/aspnet:7.0mcr.microsoft.com/dotnet/sdk:7.0

最近的dotnet版本不支持QEMU：
.NET 7不支持通过QEMU运行（模拟）。例如，QEMU用于在x64上模拟Arm64容器，反之亦然。
据我所知，没有办法在仿真下运行dotnet。在你的情况下，你能在主机上构建你的ASP.NET应用程序，生成跨平台的二进制文件（包括所有的依赖项）并将它们包含到docker镜像中吗？或者你也需要在仿真下运行你的应用程序？
