This book is about code generation for the Microsoft.NET Common Language Runtime (CLR). It guides software engineers in creating .NET compilers and implementing programming languages for the .NET environment, explains key concepts underlying .NET CLR, and demonstrates how CLR maximizes interoperability across multiple programming languages. Coverage includes background on the CLR, the compile-time representation of programs, and the emission of the intermediate language. An ongoing example illustrates key points. The author has been writing compilers for 20 years. Annotation c. Book News, Inc., Portland, OR (booknews.com)
