A Tour of Go (golang) for the C# Developer

Learning other programming languages enhances our work in our primary language. From the perspective of a C# developer, the Go language (golang) has many interesting ideas. Go is opinionated on some things (such as where curly braces go and what items are capitalized). Declaring an unused variable causes a compile failure; the use of "blank identifiers" (or "discards" in C#) are common. Concurrency is baked right in to the language through goroutines and channels. Programming by exception is discouraged; it's actually called a "panic" in Go. Instead, errors are treated as states to be handled like any other data state. We'll explore these features (and others) by building an application that uses concurrent operations to get data from a service. These ideas make us think about the way we program and how we can improve our day-to-day work (in C# or elsewhere).

C# 7 is a major update with a lot of interesting new capabilities. And while there are plenty of articles on what you can do with it, there aren't quite as many on what you should do with it. Using the principles found in the .NET Framework Design Guidelines, we're going to take a first pass at laying down strategies for getting the most from these new features.
