Doesn't install properly! I can't see the View In Diagram after installing the Extension. Possibly an environment issue?!

One of the best tools I've seen so far to visualize data structure

Great tool! When it comes to my IDE, I'm a minimalist, but this tool is a must have for any ADO.NET Data Services developer (ooops, I mean Open Data Protocol developer).

    • I have loaded the extension, but it doesn't seem to appear anywhere. There are no instruction on how to use it. How do I use it?
    • Go to here to see the tutorial for using ODATA
    • I really have to watch a video just to find where the tool is hidden?  Or is it complex enough that it is not just a "point it at an endpoint" kind of thing?
    • Once you installed this tool you can right-click on any service reference created through the "Add Service Reference" dialog and you'll see a new option in the menu called "View in Diagram". Click on that and the visualizer will come up. Then you can just click on "add all" if you want to see all the elements in the schema, or browse elements and add them as needed.
    • Pablo, i load the extension, but it doesn't appear anywhere, i try to solve the problem but any solution works. 
    • you need to do the work on a WCF Data Service Class and not on a RIA Domain Service class
