Most C# and .NET developers will be familiar with Visual Studio. There are a variety of versions available, ranging from free to many thousands of dollars annually. As of this writing, the Enterprise version was the most fully featured version, offering some of the best features for tests and testing. For our purposes, we'll be using Visual Studio Community. This is a free, fully featured development environment that should suit us well.

The Community edition does have some very important caveats. There are limitations to the software license and the use of the Community edition, based on the terms of the license agreement. Please make sure to read the terms before deciding to use Visual Studio Community edition to develop software that you intend to sell. The current terms can be found at https://www.visualstudio.com/license-terms/mlt553321/.
