Configuration

Umbraco UI Builder can be configured directly via the AddUIBuilder extension method on IUmbracoBuilder.

AddUIBuilder

To configure Umbraco UI Builder via the AddUIBuilder extension method, you can look at the Program.cs file at the root of your web project. From within this file, before the call to AddComposers() you can add the AddUIBuilder configuration.

Alternatively, if your project is upgraded from earlier versions, you can add the configuration to the Startup.cs file.

builder.CreateUmbracoBuilder()
    .AddBackOffice()
    .AddWebsite()
    .AddUIBuilder(cfg => {
                // Apply your configuration here
    })
    .AddDeliveryApi()
    .AddComposers()
    .Build();

The AddUIBuilder extension method accepts a single parameter, a delegate function with one of the Umbraco UI Builder configuration builder arguments. With this, you can call the relevant fluent APIs to define your solution.
