Silverlight—The ArcGIS Viewer for Microsoft Silverlight allows you to point and click through wizards that help you add the components you want in your application. To put a map in the app, you can browse to any map you've made in ArcGIS.com, or you can add map services interactively. You can have a ready-to-deploy Silverlight mapping application in a few minutes without writing any code.
Flex—A similar point-and-click "application builder" for creating apps with Adobe Flex is available when you download the ArcGIS Viewer for Flex. The viewer offers a variety of widgets and allows you to add maps from ArcGIS.com or your own combination of services.
SharePoint—With ArcGIS for SharePoint, you can easily add maps to your SharePoint site to share ArcGIS Server, SharePoint, and GeoRSS data. The Map Web Part includes a point-and-click configuration experience to set up the layers and tools you want to share with your SharePoint users. Or if you've already created a web map with your layers ArcGIS.com, you can open it within the Map Web Part. You can also spatially enable SharePoint lists that contain addresses or coordinates for display in the Map Web Part.
