I installed 6.0.8. I rebuilt my Silverlight Client and my Web project. I rebuilt my Model. Everything works fine on my development machine. I can run it just fine and debug etc.
 
I copied the new Ideablade.dlls to the server and placed them in the bin directory. I copied the compiled .xap and placed it in the clientbin directory. I stopped and restarted the iis server.
 
I get this error when I log into the app
 
Unable to locate type: Ideablade.EntityModel.EntityServerException, IdeaBlade.EntityModel, Version=6.0.8.0, Culture=neutral, PublicKeyToken=287b5094865421c0
 
When I look at the log, this is the last entry.

Caught exception: System.Exception: Unable to locate type: IdeaBlade.EntityModel.EntityQueryProxy`1[[LaborWare2011.User, LaborWare2011, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]], IdeaBlade.EntityModel.SL, Version=6.0.7.0, Culture=neutral, PublicKeyToken=287b5094865421c0. Check that the assembly holding this type is available in the bin/exe folder. Also check that both your

I have checked all my dlls on the server and they are 6.0.8 where is this coming from?

The error messages indicate that the server is running 6.0.8 but the XAP is still using 6.0.7.  The most likely cause of this problem - once you've ensured the XAP was built correctly, as you have - is that the browser has cached the XAP file and it's the old file which has been loaded.
 
There's much discussion of this issue in the Silverlight world; here's one thread on the SL forums - http://forums.silverlight.net/forums/t/11995.aspx, and google will bring up additional information.
 
There are a number of ways to ensure the XAP is not cached at all, or that a new XAP will be used when available.  Possibly the easiest is to append either a version number or timestamp to the URL of the XAP.  You can either hardcode the value or determine it via code.
 
Here's a simple example - change the object tag in the default.aspx to add a query parameter to the XAP URL:
 
<object data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%">
   <param name="source" value="ClientBin/SilverlightApplication.xap?ignoreme=v2"/>
  .....
</object>
