RadMediaPlayer issue...

[Marc Roussel]

Hi,

I just added a RadMediaPlayer for the first time on my form and when I build this is what I got.  Any idea ?

Error 1 The "ValidateXaml" task failed unexpectedly.
System.IO.FileLoadException: Could not load file or assembly 'file:///C:\Program Files (x86)\Telerik\RadControls for Silverlight Q3 2009 SP1\Binaries\Silverlight\Telerik.Windows.Controls.dll' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)

Thank you

I tried to unblock the file and even tought I do unblock them they stay blocked.
Because when I go back to see they're still blocked.

Could it be something about it ?
If so What do we do ?
I did the upgrade directly from Telerik menu in VS2010

I'm unable to compile my solution anymore and I need imediate help if possible

Well, this is really it.  I had to make sure I have full control over the Silverlight directory and then for each individual dll I had to UNBLOCK the file.

I just hope I will not have to do it each time I upgrade the product ?

[Marc Roussel]

I don't know if this could help others but here's what I did
I did enable "Do not preserve zone information in file attachments"
by running gpedit.msc at the command prompt.
