In most cases, containerized .NET apps run just fine “out of the box”. IDEs such as Visual Studio and JetBrains Rider provide a helpful experience called “Fast mode” that uses some magic to put your files where they need to be inside of the container, rather than rebuilding it each time you start up. This is helpful!
However, in some cases – such as one I experienced recently – a container is not well-suited for “fast mode”. There are ways to disable this in Visual Studio, but our team needed a little extra help to get it working with JetBrains Rider (which we also love!)
So, here’s the Docker.run.xml that worked for us in Rider, including a breakdown on each line, and one additional step we had to take.
