If you are currently developing addins using the 10.1.1 WPF SDK, you might run into the following error: {"License error with ArcGISRuntime. Main license has expired."}
Please note that the license of Operations Dashboard has expired about 2 weeks ago, and you will encounter problems opening/creating an operation view. You could follow the steps below to get the updated the 10.1.1 Operations Dashboard, and use it to replace the expired one:
Uninstall Operations Dashboard from Programs and Features if you have previously installed it from arcgis.com.
Install the updated Dashboard from arcgis.com. This is the build with the license issue fixed. Once completed, the application will launch automatically.
Open the application's file location (Start Task Manager > Go to the Processes tab > Right click on OperationsDashboard.exe > Click Open File Location). The folder containing OperationsDashboard.exe will open.
Copy all the files in the folder and overwrite the ones in the OperationsDashboard folder installed with the WPF SDK (e.g. C:\Program Files (x86)\ArcGIS SDKs\WPF10.1.1\sdk\OperationsDashboard. You can also find this location from the "Start External Program" property in the Debug tab of your project's property page).
When you re-run your addin project locally, it will use the updated Operations Dashboard.
Please note that if you have updated your WPF SDK to 10.2, you should not encounter the above problems. If so, please let us know.
