Support for Silverlight 5
Although the Silverlight 5 Release Candidate runtime has been released TeamPulse does not yet support it. If you have installed Silverlight 5 you will encounter an issue at startup with a long stack trace that ends with:
Exception Type: System.ArgumentNullException
Exception Message: Value cannot be null.
Parameter name: element
at MS.Internal.XcpImports.ItemsControl_GetItemsOwner(DependencyObject element)
at System.Windows.Controls.ItemsControl.ItemsControlFromItemContainer(DependencyObject container)
at Telerik.Windows.Controls.RadComboBoxItem.OnContentChanged(Object oldContent, Object newContent)
at System.Windows.Controls.ContentControl.OnContentChanged(IntPtr nativeTarget, CValue& oldContentValue, CValue& newContentValue)
In order to resolve this issue, uninstall the Silverlight 5 RC runtime and install the latest Silverlight 4 runtime. There have been issues reported uninstalling Silverlight 5 cleanly from machines. The following links may help resolve them:
Silverlight 5 support will be available in a future release.
