我可以使用Entity Framework for Web服务的非DB结果吗？

Question

I am working on a project where different data is presented via a set of web services. These web services are a front end to MS Dynamics CRM. What the services are returning is essentially a class that has an Entity (a CRM Entity) in a paged data wrapper.

[DataContract]
public class PagedData<T>
{
    [DataMember(EmitDefaultValue=true)]
    public T[] Items { get; set; }
    [DataMember(EmitDefaultValue=true)]
    public int PageNumber { get; set; }
    [DataMember(EmitDefaultValue=true)]
    public int PageSize { get; set; }
    [DataMember(EmitDefaultValue=true)]
    public int TotalCount { get; set; }
}

My app will use a web page with drop down lists to fill in the values that will go into these services. At the same time, I will be retrieving data to populate the drop down lists via these services.

I've seen articles on here about producing web services using Entity Framework, including links to here , but i have not seen much on consuming into or using Entity Framework to create a facade to a web service.

Any ideas what i should do?

Entity Framework works on any Data source that has a " EntityFramework provider"

EF providers

Providers for major Databases are available.

If the source data in memory Objects, then there is no need to Use EntityFramework. You can simply use LInq to the in memory lists/collections.

So your web page can make a WCF call to get a result. This result can be accessed in memory when it returns. I see no need for EF in that scenario. Just LINQ away
