Question 84295 in Docker Question posted in
The official documentation can be found here.

I am a newbie to docker. How can we find which .net framework is installed in a docker image?

I have copied .NET framework from my local directory and build an image by using the below Dockerfile

FROM mcr.microsoft.com/dotnet/framework/sdk:4.8-windowsservercore-ltsc2019

ADD setup C:setup

RUN cmd.exe /c start /wait C:setupNDP471DevPack.exe /q

RUN powershell -Command rm C:setup -r -Force

WORKDIR C:\Project
ENTRYPOINT ["C:\Program Files (x86)\MSBuild\14.0\Bin\msbuild.exe"]

Now I want verify that the .NET framework is whether installed or not in the image that was build?

    You can run dotnet --version to see if there’s a .NET runtime installed and which version it is. Something like this

    docker run --rm --entrypoint=dotnet <image name> --version

    You should be able to use:

    reg query "HKLMSOFTWAREMicrosoftNet Framework SetupNDP" /s

    In Visual Studio I can select my container and click "Open Terminal Window" and paste the above command.
