Microsoft Dynamics AX is part of Microsoft Dynamics family products and is used as MS platform for building ERP business solutions. This platform exists earlier than .NET framework and many ideas and concepts are taken form it and built in .NET framework and Visual Studio which will be shown in presentation. The programming language in AX is called X++, and its syntax is similar to C#. In addition to being an object-oriented programming language, it also includes embedded SQL. The idea for creating LINQ for .NET came from there. This platform was not initially developed by Microsoft but it was acquired from NavisionDamgaard and since then Microsoft is tending to integrate this as much as possible with .NET framework. With the new version of Microsoft Dynamics AX 2012, X++ programing language is now compiled to .NET Common Intermediate Language (CIL) which makes it managed language like all other .NET programing languages.
