#SemanticKernel

[Jonathan Gennick @JonathanGennick]

This book by @dfcostea on #Microsoft #SemanticKernel just went live on @ManningBooks' MEAP program this week. I hear enough about Semantic Kernel that I believe Microsoft as a winner with this tech, in the C# and .NET world at least.

Abstract classes is when you want to make family tree.
