June 27 released version .NET Core 1.0 and a number of related libraries.
Questions in the following:
How much is .NET Core in its current state ready for use as the basis of web applications? Does it make sense to go to him now, or while only study?
How stable is a .NET Core? Is it too raw for industrial applications?
What problems / "pitfalls" are there in it now, what hinders the most?
What parts of the .NET Framework API are NOT implemented in .NET Core? What are the new APIs missing in the .NET Framework?
PS So far I have found only this (partial) answer, as of April: https://stackoverflow.com/questions/36422152/is-net-core-1-0-ready-to-be-used-on-a- full-scale-production-site-yet
