JetBrains Rider
My go-to development environment. It’s not free, but it’s a jack-of-all-trades IDE that works equally well for web development, desktop development, and everything in between.
Rider has ReSharper built-in, so it performs much better than the VS plugin.
Visual Studio Code
The go-to web development IDE. Simple and expandable with plenty of extensions to add functionality. Fast and responsive.
Also makes an excellent JSON file viewer and editor.
Visual Studio still tends to be better for .NET applications overall.
ReSharper
A development tool that provides tons of refactorings, code generation, and unit testing tools. Only compatible with Visual Studio.
Agent Ransack
A text search tool that works fast over networks.
BareTail
A text file viewer that can track the end of files. Useful for viewing log files over a network.
Remote Desktop Connection Manager
An application that can store remote desktop connections and credentials. Makes it easy to manage multiple VMs.
