In theory, the major benefits of going MVVM is the complete separation of the UI and the code that is not UI related. Purist would say that a UI class like a WPF form should not contain code at all, only set elements in the XAML but this is really hard to achieve.<br />

If you can extract everything not UI related, in theory again, you could reuse that layer (the VM) and put a totally new UI (for Windows Phone for example) without having to rewrite the business layer.

MVVM WPF application

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.

.NET Programming

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).

Most development for the Microsoft platform is done utilizing the technologies supported by the.NET framework. Other development is done using Visual Basic for Applications (VBA) for programs like Access, Excel, Word and Outlook, with PowerShell for scripting, or with SQL for large databases.
