I'm similiar to you. Interested in coin development, but not comfortable with C++. 
You said you have C# skills so you might want to check out x42 coin. It's a new coin that seems to be made in .NET core technology using C#. The GUI wallet is made with Electron and Angular.
It's a POS coin that will also support DApps applications.
