I just discover this framework. I usually code in VB.NET not C#. I'd like to known if there is a way to use nano framework with VB.NET, and also if it's possible to use Jetbrains Rider instead of VisualStudio.
.NET nanoFramework only supports C#, not VB.NET. It could though. For this to happen it would require a fair amount or work in order to provide the BCL and the respective support on the execution engine. FYI, there is an open issue where this has been discussed. Despite a few attempts and some potential interest showned, it ended up without any real commitment from the community to make it happen.
