 [Mixpanel](https://mixpanel.com/) is a great analitics platform, but unfortunetally there is no official integration library for .NET. So if you are writing code on .NET and want to use Mixpanel, then ```mixpanel-csharp``` can be an excellent choice. ```mixpanel-csharp``` main idea is to hide most api details (you don't need to remember what time formatting to use, or in which cases you should prefix properties with ```$```) and concentrate on data that you want to analyze.
