It looks like the path to the image is not correct; in Docker Hub, the following are available for dotnet-framework/sdk: https://hub.docker.com/r/microsoft/dotnet-framework-sdk

Have you tried changing the `17` in this line to `16`? ```ADD https://aka.ms/vs/17/release/vs_buildtools.exe C:\TEMP\vs_buildtools.exe```
