We are using ADO.NET Entity for our ASP.NET application.

I have read that the pre-generated views improves the performance. Referred to this blog post,

I generated the views. The namespace & classes generated as

namespace Edm_EntityMappingGeneratedViews

{

/// <Summary>

/// The type contains views for EntitySets and AssociationSets that were generated at design time.

/// </Summary>

public sealed class ViewsForBaseEntitySets4D4A6E0AA7AF6B2298FABB4F22235831 : System.Data.Mapping.EntityViewContainer

{

/// <Summary>

/// The constructor stores the views for the extents and also the hash values generated based on the metadata and mapping closure and views

/// </Summary>

public ViewsForBaseEntitySets4D4A6E0AA7AF6B2298FABB4F22235831()

{

this.EdmEntityContainerName = "JSEntities";

I added this to my data layer and test the performance. Couldn't see much improvement. CPU usage always goes to 20-30% utilization (response timing is good) and reduce back to 0% in 500ms - 1 sec. I think the CPU utilization goes high because of view generation every time.

I couldn't understand how the entity framework knows that this is my pre-generated view class for my model eventhough the MyModel.edmx & MyModel.Views.cs matches with filename.

Should I have to update Web.Config or App.Config to map the View class to model somewhere?

Please clarify.

Thanks for the tip. This worked well to eliminate a 45 second startup load time in an EDMX model in which one of our tables contained 27 foreign keys to other tables.
