While testing one of the old samples I found that it is giving me an exceptions of permissions. The exception raised was Request for the permission of type 'System.Data.OleDb.OleDbPermission, System.Data, Version 2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. Upon checking I found that I have opened the project from a Network Drive location which as causing the permissions problem.
To resolve this you can simply take the copy of code to local drive and reopen the project.
Error Reporting in Silverlight is really bad. One of the most common error you see whiled developing a Silverlight application
is AG_E_PARSER_BAD_PROPERTY_VALUE.
This error mostly occurs due to following,
Version Change in assemly while you are working in the same code (i.e. you used version x initially and later on you changed it to version x + y ). Some Assemblies in 3rd party control when upgraded do not support few older properties or methods.
Your XAML code is referring to some event which is not present in the code behind file. Make sure that all XAML code has relevant code in code behind file. (Remove any unnecessary Events from XAML and CS files)
Your XAML code has repeated the same code again, causing a clash.
Hope this helps

If this doesnt resolve you problem,
Please remove all the project references from your project that gives this exception.

If you are one who has ever faced issues due to people disconnecting from the Windows Terminal Server (RDP) and not logging off? Then here is a small change you can make and it will auto-log-off Users after specific interval of disconnection.
User > Properties > Session
Open Local Users and Groups, select User and then right click and open Properties window. Click on Sessions tab. It will show up screen similar to one above. Change "End a disconnected session: <N>" to specific time you want after which a disconnected User Session will be logged off.
So basically this is a small trick to avoid issues while Users tends to forget to log-off their sessions.
I have faced problems in the past when maximum limit for Users to connect comes to an end and you don't have any choice but to Restart the server, even "mstsc /console" don't work..! I had such experience with one of the dedicated Windows server on 1and1.com.
This happens if you dont have the Silverlight Debugger Attached to the Web project in your solution.
Right Click the Web Project and go to Web tab under properties. Please check the Silverligth Debugger as shown in the Image below, you will be able to Debug
