Microsoft Visual Programming Language, or MVPL, is a visual programming and dataflow programming language developed by Microsoft for the Microsoft Robotics Studio. The Microsoft Visual Programming Language is distinguished from other Microsoft programming languages such as Visual Basic and C#, as it is the only Microsoft language that is a true visual programming language. Microsoft has utilized the term "Visual" in its previous programming products to reflect that a large degree of development in these languages can be performed by "dragging and dropping" in a traditional wysiwyg fashion.
