From Java to .NET Core, Part 2: Types

Yev Bronshteyn

In my previous post in the series, I discussed some fairly surface-level differences between C#/.NET and Java. These can be important for Java developers transitioning to .NET Core, to create code that looks and feels "native" to the new ecosystem. In this post, we dig beneath the surface, to understand .NET's type system. It is my belief that, with Java in the rear view mirror, the .NET type system is more effective and enjoyable to write on. But you be...

From Java to .NET Core. Part 1

Yev Bronshteyn

There was a time when the word ".NET" was virtually synonymous with bloat, vendor lock-in, and Windows. .NET Core is the exact opposite. It's blazingly fast. It's open source under a permissive license (Mostly MIT, some parts Apache-2.0). Unlike some other open-source platforms, .NET Core's Contributor License Agreement does not grant exclusive privileges to a single corporation. .NET Core is cross-platform, allowing you to target Windows, Mac, Docker, and many flavors of Linux. My favorite resource for getting started with...
