Hmm. Firstly, I don't know what your colleague has written so can't comment on how suitable/comprehensive it would be.

My favourite approach to a .NET web project is using WebApi with angular (and a minimum amount of MVC). In that scenario .NET's role is pretty much limited to serving up data - angular is your framework. Best use EntityFramework or nHibernate so that you always (outside the data layer) deal with objects rather than ADO.NET tables/rows/columns.

Choosing a framework for the desktop won't be easy - there are too many offerings out there. Some are better (or only) for WPF, some for WinForms and no single framework can work well with both. You probably first need to decide whether this will be WinForms or WPF.
