I have Visual Studio 2010 and I have installed the 1.0.1 Silver light viewer for ArcGIS. I wanted to try and create some add-ins but I am having issues. I've installed both of these:
ArcGISExtensibility2_4__en
ArcGISSilverlightViewer1_0_1_x64_en
However, when I go to VS2010 and click on File/New/Project/Other Languages/Visual C#/Silverlight/ I only have these options:
Silverlight Application
Silverlight Class Library
Silverlight Navigation Application
I do not see anything ESRI. What am I doing wrong?
