C# 7.0 All-in-One For Dummies

Book description

Sharpen your knowledge of C#

C# know-how is a must if you want to be a professional Microsoft developer. It's also good to know a little C# if you're building tools for the web, mobile apps, or other development tasks. C# 7.0 All-in-One For Dummies offers a deep dive into C# for coders still learning the nuances of the valuable programming language. Pop it open to get an intro into coding with C#, how to design secure apps and databases, and even pointers on building web and mobile apps with C#.

C# remains one of the most in-demand programming language skills. The language regularly ranks in the top five among "most in-demand" languages, typically along with Java/JavaScript, C++, and Python. A December 2016 ZDNet article noted 'If your employer is a Microsoft developer, you better know C#." Lucky for you, this approachable, all-in-one guide is here to help you do just that—without ever breaking a sweat!

Includes coverage of the latest changes to C#

  • Shows you exactly what the language can (and can't) do
  • Presents familiar tasks that you can accomplish with C#
  • Provides insight into developing applications that provide protection against hackers

If you have a basic understanding of coding and need to learn C#—or need a reference on the language in order to launch or further your career—look no further.
