WebApiOptions.UseResourceDelta Property

Specifies the type Web API uses to track EF Core and non-persistent object changes.

Namespace: DevExpress.ExpressApp.WebApi.Services

Assembly: DevExpress.ExpressApp.WebApi.v26.1.dll

Declaration

C#

public bool UseResourceDelta { get; set; }

VB.NET

Public Property UseResourceDelta As Boolean

Property Value

Type	Description
Boolean	true to use the DevExpress.ExpressApp.WebApi.EFCore.ResourceDelta<T> type; false to use the Microsoft.AspNetCore.OData.Deltas.Delta<T> type.

Remarks

XAF Web API Service uses the DevExpress.ExpressApp.WebApi.EFCore.ResourceDelta<T> class to track changes in EF Core and non-persistent objects. Disable the UseResourceDelta property to use the standard Delta<T> class instead. In this case, some complex update scenarios, such as Deep Update, may cause runtime exceptions.

SolutionName.WebApi\Startup.cs

builder.AddXafWebApi(webApiBuilder => {
    webApiBuilder.ConfigureOptions(options => {
        options.UseResourceDelta = false;
        // ... Other options
    });
});
