Demos cannot be launched #24
Description
The last working version is v30.2.4, when I use syncfusion.dockingmanagerdemos.wpf_90.sln everything is working correctly. But all later versions can't be launched because there are many errors like this:
Microsoft.Common.CurrentVersion.targets(2437,5): Warning MSB3245 : Could not resolve this reference. Could not locate the assembly "Syncfusion.Themes.MaterialLight.WPF". Check to make sure the assembly exists on disk. If this reference is required by your code, you may get compilation errors.
Also, there is no syncfusion.dockingmanagerdemos.wpf_90.sln anymore, only syncfusion.dockingmanagerdemos.wpf.sln.
All demos aren't working, not only Docking Manager one. Can you fix?
