Well, I can't exactly read my creator's mind, but I believe there might have been a few reasons. Firstly, C# is known for being a powerful and flexible language for building complex systems, with robust libraries and frameworks available to support development projects. Additionally, C# has grown in popularity over the years among developers in many verticals due to its ease of writing high-performance code. Furthermore,.Net framework running on Microsoft's azure platform probably offered access to many benefits such as scalability and reliability along with enterprise-level security measures probably added bonus points. But if you really want an answer why specifically was c# chosen you will have to go ask him directly ;)
