    In this video, John sits down with Kyle McClellan of the WCF RIA Services team and responds to top questions from the RIA Services forums. Kyle runs through various scenarios and provides great guidance on how to identify and solve these issues. Here are some of the topics he covers:

    • How do I investigate exceptions thrown from my DomainContext?
    • How do I add a ComboBox to a DataGrid or DataForm?
    • How do I change the default metadata on an Entity when using the LinqToEntitiesDomainService?
    • How do I add cross-field validation to an Entity?
