The Modern C# Challenge

• Perform statistical calculations such as finding the standard deviation
• Find combinations and permutations
• Search directories for files matching patterns using LINQ and PLINQ
• Find areas of polygons using geometric operations
• Randomize arrays and lists with extension methods
• Explore the filesystem to find duplicate files
• Simulate complex systems and implement equality in a class
• Use cryptographic techniques to encrypt and decrypt strings and files

C# is a multi-paradigm programming language. The Modern C# Challenge covers with aspects of the .NET Framework such as the Task Parallel Library (TPL) and CryptoAPI. It also encourages you to explore important programming trade-offs such as time versus space or simplicity. There may be many ways to solve a problem and there is often no single right way, but some solutions are definitely better than others. This book has combined these solutions to help you solve real-world problems with C#.

In addition to describing programming trade-offs, The Modern C# Challenge will help you build a useful toolkit of techniques such as value caching, statistical analysis, and geometric algorithms.

By the end of this book, you will have walked through challenges in C# and explored the .NET Framework in order to develop program logic for real-world applications.

• Gain useful insights on advanced C# programming topics and APIs
• Use locking and cached values to solve parallel problems
• Take advantage of .NET's cryptographic tools to encrypt and decrypt strings
