The application configstatemachine is a very simply application still ready.
There is a field in this application :
see figure 3, field PreviewInfo that have the following problem:
I need to write in preview info also < and > charatters OR xml field.
Actually the application producer errors because if I write < > inside the field is checked by the ASP environemnt and prouce an error.
This problem as still solved in XML field of the same page, so you will need to do the same , use the same type of component used for XML field also in Preview Info.
I will upload the source code if you will accept the job.
