 The <xref:Microsoft.AspNetCore.Components.Forms.DataAnnotationsValidator> component attaches data annotations validation to a cascaded <xref:Microsoft.AspNetCore.Components.Forms.EditContext>. Enabling data annotations validation requires the <xref:Microsoft.AspNetCore.Components.Forms.DataAnnotationsValidator> component. To use a different validation system than data annotations, use a custom implementation instead of the <xref:Microsoft.AspNetCore.Components.Forms.DataAnnotationsValidator> component. The framework implementations for <xref:Microsoft.AspNetCore.Components.Forms.DataAnnotationsValidator> are available for inspection in the reference source:
 
 * [`DataAnnotationsValidator`](https://github.com/dotnet/AspNetCore/blob/main/src/Components/Forms/src/DataAnnotationsValidator.cs)
-* [`AddDataAnnotationsValidation`](https://github.com/dotnet/AspNetCore/blob/main/src/Components/Forms/src/EditContextDataAnnotationsExtensions.cs)
+* [`EnableDataAnnotationsValidation`](https://github.com/dotnet/AspNetCore/blob/main/src/Components/Forms/src/EditContextDataAnnotationsExtensions.cs)
 
 If you need to enable data annotations validation support for an <xref:Microsoft.AspNetCore.Components.Forms.EditContext> in code, call <xref:Microsoft.AspNetCore.Components.Forms.EditContextDataAnnotationsExtensions.EnableDataAnnotationsValidation%2A> with an injected <xref:System.IServiceProvider> (`@inject IServiceProvider ServiceProvider`) on the <xref:Microsoft.AspNetCore.Components.Forms.EditContext>. For an advanced example, see the [`NotifyPropertyChangedValidationComponent` component in the ASP.NET Core Blazor framework's `BasicTestApp` (`dotnet/aspnetcore` GitHub repository)](https://github.com/dotnet/aspnetcore/blob/main/src/Components/test/testassets/BasicTestApp/FormsTest/NotifyPropertyChangedValidationComponent.razor). In a production version of the example, replace the `new TestServiceProvider()` argument for the service provider with an injected <xref:System.IServiceProvider>.
