Joe Mayo - C# Cookbook: Modern Recipes for Professional Developers

When brainstorming for this book, the entire focus was on answering the question What do C# developers need to do? Looking at the list, certain patterns emerged and evolved into chapters:

• One of the first things I do when writing code is to build the types and organize the application. So I wrote to show how to create and organize types. Youll see recipes dealing with patterns because thats how I code.

• After creating types, we add type members, like methods, and the logic they contain, which is a natural category of recipes for .

• What good is code unless it works well? Thats why I added , which contains recipes that help improve the quality of code. While this chapter is packed with useful recipes, youll want to check out the recipe that shows how to use nullable reference types.

While Chapters to the end of the book I break away, taking a technology-specific focus:

• Many people think of Language Integrated Query (LINQ) as a database technology. While LINQ is useful for working with databases, its also excellent for in-memory data manipulation and querying. Thats why discusses what you can do with the in-memory provider, called LINQ to Objects.

• Reflection was part of C# 1, but dynamic programming came along later in C# 4. I think its important to discuss both technologies in and even show how dynamic programing can be better than reflection in some situations. Also, be sure to check out the Python interop recipes.

• Async programming was a great addition to C# and seems straightforward, on the surface. covers async with recipes that explain several important features you might not be aware of.

• All apps use data, whether securing, parsing, or serializing. includes several recipes covering different things you want to do with data. It focuses on some of the newer libraries and algorithms you might want to use for working with data.

• One of the largest transformations of the C# language occurred over the last few versions in the area of pattern matching. There are so many that I was able to fill with only pattern-matching recipes.

• C# continues to evolve and captures recipes dedicated to C# 9. Well look at some of the new features and discuss how to apply them. While I provide insight in the discussion, remember that sometimes new features can become more integral to a language in later versions. If youre into the cutting edge, these recipes are pretty interesting.
