C# Compiler as a Service (User the C# compiler as a library)
C# Interactive Shell
Full static compilation of .NET code (use by Xamarin.iOS & PlayStation 3)
Mono coroutines (used to implement micro-threading code and continuations, mostly used for games)
Assembly injection to live processes
Use of LLVM as JIT backend

Indexers
An indexer in Azure Search is a crawler that extracts searchable
data and metadata from an external data source and populates an
index based on field-to-field mappings between the index and
your data source.
Indexers are based on data source types or platforms, with
individual indexers for SQL Server on Azure, Cosmos DB, Azure
Table Storage and Blob Storage, and so forth.
