A lot of code should <i>just work</i>, some will require a rebuild under the new environment... I don&#x27;t think I&#x27;ve had many problems moving forward at any given point.  I&#x27;ve been using C#&#x2F;.Net since some of the early previews.  Though, these days most of my time is spent with node.js, and I&#x27;ve been following rust and go with some interest.
