visual-studio docker dotnet-7 debugging C#

I've been banging my head against this for hours... I've been banging my head against this for hours. I'm having trouble configuring the debugging environment for my Dockerized .NET 7 application in Visual Studio 2022. I set up a Dockerfile and everything seems correct, but when I try to start debugging, I get the following behavior: `The program 'dotnet' has exited with code 127 (0x7F)`. My Dockerfile looks like this: ```dockerfile # Use the official .NET SDK image FROM mcr.microsoft.com/dotnet/sdk:7.0 AS build WORKDIR /app COPY . . RUN dotnet restore RUN dotnet publish -c Release -o out # Use the official ASP.NET runtime image FROM mcr.microsoft.com/dotnet/aspnet:7.0 WORKDIR /app COPY --from=build /app/out . EXPOSE 80 ENTRYPOINT ["dotnet", "MyApp.dll"] ``` I've ensured that Docker is running and I've also checked that the application runs fine outside of Docker using `dotnet run`. In Visual Studio, I have set the launch settings like this: ```json { "profiles": { "Docker": { "commandName": "Docker", "launchBrowser": true, "environmentVariables": { "ASPNETCORE_ENVIRONMENT": "Development" } } } } ``` I've tried rebuilding the solution and also resetting Docker settings, but the same behavior continues. What could be going wrong here? Any help would be appreciated, especially with how to correctly set up debugging for a Docker container in Visual Studio 2022 with a .NET 7 application. I'm working on a API that needs to handle this. This is part of a larger API I'm building. What's the best practice here?
