AddIn file is not created

[ModyBuchbinder]

I have an AddIn solution in VS2012 that was working fine in 10.1

Now I open it in 10.3 machine, fix the references and rebuild.

The rebuild gives no mistakes. New dll's are created but the AddIn file is not created.

Anybody have an idea?

What in the solution is responsible for that build? I found nothing in the post build process.

Thanks

Mody

I believe you're running into a known issue. You'll want to unload your project and change the target to ESRI.ArcGIS.AddIns.11.targets in your csproj or vbproj. You'll also want to make sure that the version of the addin is the same as the version you're compiling against.
