C# 10.0

Even if you have past experience with C#, the new features in C# 10.0 will have you producing feature-rich applications in an even shorter time than you may have before. C# 10.0 All-in-One For Dummies introduces you to all these new features. For example, you discover how to work with both Universal Windows Platform (UWP) and Windows 10 and above applications (besides using all the old standbys).

• • Web addresses and programming code appear in monofont. If you’re reading a digital version of this book on a device connected to the Internet, you can click the live link to visit a website, like this: www.dummies.com.

• When you need to click command sequences, you see them separated by a special arrow, like this: File ⇒   New File, which
