We plan on moving to it sometime this year, from "old" dotnet. The timings is unclear because it depends on a few factors both on our side and from Microsoft/the community. For example we are on trend of using Entity Framework less in favor of dapper, so when the bits we are still using are fully supported by entity framework core that block will be cleared. Other big dependencies like a posgresql driver are already ready to go IMO. Tooling still isn't 100% ready in visual studio 2017 with web deployment being a key problem.

My advice would be to only use it now if you are starting from scratch and you have no business goals in the next 6 months (you are building an MVP and can take the hit of some random bugs in production). I know that at least one startup is using it for critical services, but they are also committed to fixing the dotnet core source code when they run into a problem and I believe are part of the reason for the good pref of kestrel (new web server), I think unless you are willing to do that you should wait a bit longer.
