Hi, I am looking for some help in integrating my UI designer with Visual Studio. The idea is silmiar to VS Class designer or Entity designer. 1. when the file is select, the designer is open. 2. it updates the file when the visual elements are changed. 3. it generates source code file. One visual elements represents one class. When the visual elements change, the source code also change accordingly. for example, the element is renamed, then the class name is changed and all reference are changed automatically like renaming a class in Visual Studio. Any information is appreciated. Thanks Carey
