.NET R&D Digest (April, 2019)

There are a lot of good technical articles & books on Web. I see them all the time – when trying to find a solution, when investigating things or simply when reading new posts from my RSS Feed during breakfast.

Having all these knowledge only for myself was a bit selfish. That is why once a month or two I compose some of this content into a so called ‘digest’ for colleagues & friends.

After fourth issues (this one is the fourth) I though – maybe this can be interesting for my readers? So this is the Aprils issue of .NET R&D Digest.
