and the new dll's that I am using are --> 2010.3.1110.1040..

Hi,

I believe that you cannot use Silverlight 4 assemblies in Silverlight 3 environment.

So,

did we buy the wrong version...i think there was a bit of confusion at check out...?

we are using ---> RadControls_for_Silverlight_4_2010_3_1110_DEV

can we also get the Silverlight 3 assemblies.

thanks

Hi,

 We discontinued Silverlight 3 support more than six months ago. 

Best wishes,

[Leon]

thats fine,

but can I still have the assemblies for 3.0...this is mission critical..

I downloaded the trial version about 3 months ago(which contained both 3.0 and 4.0)...and have been using it since...

Please let me know ASAP!

Hi Leon,

Yes, you can use the SL 3 assemblies that are available in your account with no problem.
Just be warned that we will not release any new versions to those assemblies. Our SL3 development and support is discontinued.

Kind regards,
