Here's a nice way to bind to mouse events to a RoutedCommand. My RoutedCommand is defined in a ViewModel (in the Model-View-ViewModel pattern):

<Image Name="Image" Grid.Row="0"
           Source="{Binding DataModel.Thumbnail, Converter={StaticResource
                        ImageConverter}}">
    <Image.InputBindings>
        <MouseBinding MouseAction="LeftDoubleClick"
                            Command="vm:ThumbnailViewModel.PreviewCommand"/>
    </Image.InputBindings>
</Image>

While trying to create unit tests for view models (using the Model-View-ViewModel pattern), I came across a problem while trying to execute unit tests from NUnit. The error I recevied was:

The calling thread must be STA, because many UI components require this.

A quick search on Google yielded an answer.

However, the configuration file in the post was incorrect and was noted by a commentor. For expediency, I have included the correct configuration text below:

<configSections>
   <sectionGroup name="NUnit">
      <section type="System.Configuration.NameValueSectionHandler" name="TestRunner"></section>
   </sectionGroup>
</configSections>

<NUnit>
   <TestRunner>
      <add value="STA" key="ApartmentState"></add>
   </TestRunner>
</NUnit>
