You can set the ControlTemplate of your TextSymbol and apply a RotateTransform for the symbology of your Graphic:

<esri:GraphicsLayer ID="MyGraphicsLayer">
 <esri:Graphic>
  <esri:Graphic.Symbol>
   <esri:TextSymbol FontFamily="Arial" FontSize="14" Foreground="Black">
    <esri:TextSymbol.ControlTemplate>
     <ControlTemplate>
      <Grid RenderTransformOrigin="0.5,0.5">
       <Grid.RenderTransform>
        <RotateTransform Angle ="-90" />
       </Grid.RenderTransform>
       <TextBlock Text="My Text" />
      </Grid>
     </ControlTemplate>
    </esri:TextSymbol.ControlTemplate>
   </esri:TextSymbol>
  </esri:Graphic.Symbol>
  <esri:MapPoint X="-10.609" Y="23.729" />
 </esri:Graphic>
</esri:GraphicsLayer>

Another solution is to create your own RotatingTextSymbol by inheriting from MarkSymbol. Add new DependencyProperty for Text, HorizontalAlignment, and Angle.

Create the ControlTemplate such that it contains a TextBlock with RotateTransform. You can bind the TextBlock's Text and HorizontalAlignment to the Symbol's Text and HorizontalAlignment properties. Similarly, you can bind the RotateTransform's Angle to the Symbol's Angle.
