Do you know this about RIA service:

RIA services strictly follow Naming convention and signatures.Like Method that are meant to query and return data to the client should begin with one of the following prefixes:Get,Fetch,Query,Retrieve and Select.This methods should have return type as IEnumerable, IQueryable, or a single instance of the entity type.However, you can have any number of parameters in a query method, which can help you to filter the results. Below Table lists the various combinations of naming conventions that you can follow when you add your own CRUD operations, if you wish for them to be exposed by the WCF RIA Services framework.

Data method

Required Method Prefix

Required Method Signature

Query Data Get, Fetch, Query, Retrieve,

or Select

IEnumerable<T> GetData()

IQueryable<T> GetData()

Create Data Insert, Add, Create void InsertData(T entity)
Update Data Update, Change, Modify void UpdateData(T entity)
Delete Data Delete, Remove void DeleteData(T entity)

If, for some reason, you are unable to follow the WCF RIA Services naming conventions in your own custom methods, you also have the option of adding specific attributes above the method declarations.

The WCF RIA Services framework also looks for these attributes when determining which methods to make available to clients. You can use any of the following attributes above your custom methods: [Query], [Insert], [Update], and [Delete]. For example, if you have a method that searches for specific foods called FindExercises, by default, this method is not exposed to the client.

If you were to add the [Query] attribute directly above the method declaration then the framework would, in fact, expose it to clients.

    Howdy! I know this is kinda off topic however , I’d figured I’d ask.
    Would you be interested in trading links or maybe guest authoring a blog article or
    vice-versa? My website covers a lot of the same topics as yours and I believe we could greatly benefit from
    each other. If you are interested feel free
