I would also be excited, unfortunely in what concerns Web development we never do everything from scratch, rather build on top of Sitecore, SharePoint, Dynamics, while destop stuff always ends up having some 3rd party commercial components like Telerik, ComponentOne, Office or VS Plugins,...

I don't know if by we you mean us C# users or the people you work with.

If it is the former I can say that I never ever built on top of Sitecore or SharePoint. Recently only Asp.NET Core or whatever it is called now.

Naturally us, the clients I work with.
