I get an error in Visual Studio when editing my MainWindow.xaml:
InvalidOperationException: Error initializing ArcGISRuntimeEnvironment. Unable to find ArcGISRuntime deployment folder. To create a deployment run the ArcGISRuntime Deployment Tool to create a folder called arcgisruntime10.2.6. Place this in the same folder as your exe, or set the ArcGISRuntimeEnvironment.InstallPath to point to a different location. This deployment folder must contain sub-folders matching your process architecture. For developers you can also install the ArcGIS Runtime .Net SDK, which includes a deployment folder.
That is the reason why Visual Studio does not show any esri objects in the Design-Window and marks any esri objects as error in the xaml window.
The strange thing is: this has worked for many days now without any problems so far. I could not remember that I have changed anything, I justed opened up my project.
But: even if I get error messages in the designer, I could compile and run the programm without any problems! So it seems to be a problem of the designer, but it is annoying.
Any one have an idea how to get a solution for this problem?
