It is easier to develop apps in VFP than .NET, but you are fairly limited in what you can do in VFP without resorting to hacks or 3rd party frameworks.

.NET winforms and console applications are pretty simple to develop - not much harder than VFP and they have a lot more built-in functionalities with the .NET framework.

.NET web applications are a completely different paradigm simply due to the stateless nature of web programming (and the inner workings of ASP.NET). That was the biggest hurdle for me to learn of all the .NET technologies I've worked with.

.NET WPF and Silverlight applications toss XAML into the coding mix and WCF services into the data tier, but really aren't that bad compared to Winforms and ASP.NET respectively.

Mobile development becomes very platform specific. You can develop for all the major mobile platforms in Visual Studio, but .NET only applies to Windows Phone 7 and Mono based Android development. Third party frameworks make Apple and cross platform development possible, although I have not been impressed by any of the cross platform stuff.

Ignore Tore's .NET is Dead rant BTW.
