Re: Silverlight RIA Services
Have you tried hitting the service directly in a browser?
You can do a basic check to ensure that the domain service is actually being
hosted.
If your fully qualified class name was
Myapp.RiaProject.Services.MyDomainService
then you would browse to it by just replacing the dots with - and adding
.svc
localhost:1234://Myapp-RiaProject-Services-MyDomainService.svc

Hi Shingi,
It all look right to me, however, I am curious about the static
declaration on title within the metadata class. Is there a reason why it is
static?

It is likely that you didn't declare any ria service operation

For example, have you got any [Insert], [Update], [Delete], [Query]

RE: Silverlight RIA Services
If you don't have the namespaces the same for the two parts of the partial
class it can fail also.
Have a look in the generated file (Show all files and look for the .g.cs
file) and see if the Title class exists in there.

Hi Shingi, It sounds like the object does not exist within the generated code within the Silverlight component. This means that the object is not shared properly from the web app. There are a number of reasons for this - perhaps you don't have an [EnableClientAccess] attribute on your class?

Re: Silverlight RIA Services
Also try deleting the Generated_Code folder from under your Silverlight project's folder. That forces the client side regeneration (which I've personally found more reliable than cleaning / rebuilding the solution).
