As developers, we spend ours days writing code. What if we could get the computer to write it for us? Using the .NET Roslyn APIs, we can do exactly that! In this session Steve will share his latest work at Elastic, generating the majority of the .NET client for Elasticsearch from a simple specification. Steve will introduce and demonstrate how to get started with leveraging the Roslyn APIs. He will show you how the Elastic .NET code generator transforms a JSON spec into a C# syntax tree and outputs thousands of classes in only a few seconds. You'll leave this session with an understanding of the Roslyn APIs and how you can leverage them in your work. You'll understand core concepts such as syntax trees, the SyntaxFactory and tools to help you write code with code.
