Do you like to deep dive into specific ASP.NET Core and .NET Core topics? If yes, you definitely should bookmark Steve Gordon's blog about .NET Core and ASP.NET Core. Steve is a senior .NET developer and Microsoft MVP working in Brighton, East Sussex (UK). He's working on various open source projects, a quite active part of the .NET developer community and running a .NET user group in Brighton.
What I just learned while writing this post is, that he also has a channel on YouTube: https://www.youtube.com/channel/UC_rMpypHGP8_J8AAo_bLCmA/videos
