Introducing Software Verification with Dafny Language

Get introduced to software verification and proving correctness using the Microsoft Research-backed programming language, Dafny.  While some other books on this topic are quite mathematically rigorous, this book will use as little mathematical symbols and rigor as possible, and explain every concept using plain English. It's the perfect primer for software programmers and developers with C# and other programming language skills.
Writing correct software can be hard, so you'll learn the concept of computation and software verification. Then, apply these concepts and techniques to confidently write bug-free code that is easy to understand. Source code will be available throughout the book and freely available via GitHub.
After reading and using this book you'll be able write correct, big free software source code applicable no matter which platform and programming language you use.
