I have made a Button addin for ArcMap in Visual Studio 2010, but I don't know how to deploy it.
I tried debugging it from ArcMap but nothing happens.
For deploying without any setup tool, double-click the *.esriAddIn file. This file could be found in the debug folder, after build the project in Visual Studia 2010. Add-ins for ArcGIS Desktop 10
