Scenario1

In this scenario, I would like to make a read-only entityset for Products. I am commenting out the line which creates the Edit link. This is from the ODataService sample.

ODataModelBuilder modelBuilder = new ODataModelBuilder();
var products = modelBuilder.EntitySet<Product>("Products");
//products.HasEditLink(entityContext => entityContext.UrlHelper.Link(ODataRouteNames.GetById, new { controller = "Products", id = entityContext.EntityInstance.ID }));

For the following request:
GET http://kirandesktop:50231/Products(49) I am seeing the following exception in the formatter write: No EditLink factory was found. Try calling HasEditLink on the EntitySetConfiguration for 'Products'.

System.InvalidOperationException occurred
HResult=-2146233079
Message=No EditLink factory was found. Try calling HasEditLink on the EntitySetConfiguration for 'Products'.
Source=System.Web.Http.OData
StackTrace:

   at System.Web.Http.OData.Builder.EntitySetLinkBuilderAnnotation.BuildEditLink(EntityInstanceContext context) in d:\Runtime\src\System.Web.Http.OData\OData\Builder\EntitySetLinkBuilderAnnotation.cs:line 88

InnerException:

Scenario2

• I am receiving errors for the following[1] Has<>Link actions…a scenario for HasEditLink is that, a user might want to show edit links only for specific instances, let’s say based on some criteria… I do not see much use case as to when a user would not want to generate an Feed link though…
• These[2] work fine…I do not see much use case as to when a user would not want to generate an Id link though…
• For this[3], I am seeing that the links are still being generated…
