Hello,

I installed service pack and now everything is working fine.

and i found why mymap.zoomtoresolution is not working its because i am using effect

ESRI.PrototypeLab.ShyBasemap.TintShaderEffect effect = new ESRI.PrototypeLab.ShyBasemap.TintShaderEffect();
    effect.TintColor = Color.FromArgb(255, 240, 240, 240);
    ArcGISTiledMapServiceLayer l = (ArcGISTiledMapServiceLayer)this.MyMap.Layers["BaseLayer"];
    l.Effect = effect;

so when i comment this code everything works fine in SL5 also

but i want to give effect to basemap can you please help me?how to fix this bug?or any one know latest prototypelab's latest dll?which works on SL5 also?

Please help,
Thanks

I installed silverlight 5 and silverlight dev run time 5 and i am able to debug it but

To be able to create Silverlight5 project in Visual Studio you need to install Microsoft® Silverlight® 5 Tools for Visual Studio® 2010 SP1

That being said, my undestanding is that your Silverlight 4 application is not working with the Silverlight 5 runtime. Correct?
That's strange, Silverlight5 runtime is supposed to be backward compatible and support SL4 application.

Could you debug your SL4 application and give us some info about the stack trace when the error occurs? That might give a clue.

Thanks
