My application console application is build on .net core 7 and gave error when running on docker container, several other console applications running properly but one gave problem. Docker container logs given below: Targer OS is linux. I have tried delete docker image, tried delete project and create new problem still retain. Please note that other console applications developed on .net core 7 running properly the new one gave problem that recently added.

The above error is generic error the original one is inside the output window of visual studio when this prompt occurred. By the way this was because of runtime in my docker file but there should be aspnet "red underlined" below image.

I'm also getting the same error. Any suggestion? Thanks

I would guess you are pulling a docker container without the core runtime installed. show your docker file

Hi @Faisal suleman

Try to use dotnet --list-sdks and dotnet --list-runtimes commands to check the installed SDK and runtime. If you can't find the specified SDK or runtime, you can find them from here, try to install them or you can re-install the Asp.net Core 7.0.0 version. Refer to this thread. Finally clear and rebuild the project or restart the application.

Hi,

I solved this problem by replacing "FROM mcr.microsoft.com/dotnet/runtime:6.0 AS base" to "FROM mcr.microsoft.com/dotnet/aspnet:6.0 AS base"

note it was working with "runtime:6.0" when I had removed my classes libraries dependencies

hope it's help

Hi - i had the same effect/error as well. Many projects directly run with docker-support in VS, only one showed the above error. I honestly don´t know why this special one needs aspnet-runtime, but i fixed it by changing the line

FROM mcr.microsoft.com/dotnet/runtime:6.0 AS base

to

FROM mcr.microsoft.com/dotnet/aspnet:6.0 AS base

like suggested above.

But there is another stephole: after changing the line, you have to close/open visual-studio to really get this change in the docker runtime. The reason is, that VS creates a docker-debug-container when you choose a 'Docker' launch-setting. This container is only created once, and maps your local source-directories in the container (+ the vs-debugger).

The container is destroyed automatically, when you close VS and only recreated (parsing the changed dockerfile), when you restart it.

Perhaps this helps someone - if you have an idea how to find out why the aspnet-runtime is needed, please give me a hint. The project file targets 'net6' like all the other ones. Gives me some headache...
