Perhaps your mobile development project calls for a fully-featured dev framework that can meet more elevated demands. When that happens, you can always turn to Framework 7, a mobile and web app development that can work with you to create full-fledged apps. Ironically enough, most Framework 7 users go with it for prototyping.
The .NET Framework (pronounced as "dot net") is a software framework developed by Microsoft that runs primarily on Microsoft Windows. It includes a large class library called Framework Class Library (FCL) and provides language interoperability (each language can use code written in other languages) across several programming languages.
