Estou desenvolvendo uma aplicacao simples seguindo esse tutorial de como binding no datagrid com silverlight e linq.(http://www.c-sharpcorner.com/UploadFile/dpatra/386/Default.aspx)
Segui normalmente o tutorial mas na hora de fazer a referencia ao arquivo do wcf apresenta o seguinte erro
Metadata contains a reference that cannot be resolved: 'http://localhost:5303/Service1.svc'.
The server did not provide a meaningful reply; this might be caused by a contract mismatch, a premature session shutdown or an internal server error.
If the service is defined in the current solution, try building the solution and adding the service reference again.
