Addin not visible in Silverlight Application Builder

Question

I am trying to add a very simple addin to the Silverlight Application builder 3.0. Just as a test I built a .xap with the example configurable behavior and tool. Both the behaviour and tool are working fine in Visual Studio. I have not changed anything in the example that ships with the ArcGIS Silverlight Viewer Extensibility SDK.

When I add the compiled .xap addin in the application builder the xap file is uploaded without any errors but neither the behaviour nor tool are added in so I can include them in my website. The addin detail window is blank even though the addin has one behaviour and one tool.

Has any come across this issue before?

I am running Visual Studio 2010 SP 1
Windows 7 Ultimate Service Pack 1 (64 bit)
ArcGIS for Viewer for Silverlight 3.0
Microsoft Silverlight 5 SDK and the Toolkit

Any pointers greatly appreciated.

Makari.

Has anybody found a fix for this?  I am experiencing this too, and it is really frustrating.  I have an add-in with 10+ tools, and now I can no longer build new apps.

I've run into this problem before, and found that the browser caching is the culprit.

When running fiddler2, I noticed that it wasn't even sending out a request for the updated Tools.xml file.

I think Esri could fix this by having the Builder app and the built apps "dirty" these requests (e.g. add a timestamp to the url) so that the browser doesn't cache them.

Clearing the cache is a pain ... especially when I have other things that I want to remain in the cache.

Anobody resolved that ? I'm having the same issue and nothing seems to fix it.
