Hey, I am working in visual studio to build a asp.net 4 application with a sql backend database which loads visio objects. It would be accessed in a public cloud. I am unzipping the .vsdm to review and recode each file as necessary. Connections.xml holds the database queries mapping visio external data. There are lots of other files which I have not analyzed yet. I am hoping this thread continues and helps us all to have the ability to start programmatic web enabled (mvc) our visio'. My first question would be, has anyone built a .vsdm visio/with macros and external data in visual studio (addin) to support asp.net?
