Hi,
I had this problem back in the spring when I was first evaluating these component and had to eliminate them from consideration due to this issue. As we had an upgrade to the Silverlight runtime and tools this week (as well as upgrades to the Telerik components), I had hoped we'd be past this, but apparently it's still an issue.
I downloaded the latest binaries from Telerik yesterday, and built the simplest project I could with the RadScheduler component - the XAML for my page is:
<UserControl
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d"
x:Class="RadScheduleTest.MainPage"
Width="640" Height="480">
<Grid x:Name="LayoutRoot" Background="White">
<telerik:RadScheduler Margin="15" d:LayoutOverrides="Width, Height" ViewMode="Week"/>
</Grid>
</UserControl>
I used Blend 4 to create this project and it worked, but when I closed Blend and then returned the to project I got this on the Blend artboard:
An Exception was thrown.
Exception: Error HRESULT E_FAIL has been returned from a call to a COM component.

I'd really love to use the RadScheduler, but I can't until this is resolved.
