Adds a DataAPIBuilder application to the application model. Executes the pre-built containerized DataAPIBuilder engine.

```csharp
public static class DataApiBuilderHostingExtension
{
    public static IResourceBuilder<DataApiBuilderContainerResource> AddDataAPIBuilder(
        this IDistributedApplicationBuilder builder,
        string name,
        params string[] configFilePaths)
    {
        // ...
    }
}
```

## Parameters

- `builder` (`IDistributedApplicationBuilder`)
  The `Hosting.IDistributedApplicationBuilder` to add the resource to.
- `name` (`string`)
  The name of the resource.
- `configFilePaths` (`string[]`)
  The path to the config or schema file(s) for Data API Builder.

## Returns

`IResourceBuilder<DataApiBuilderContainerResource>` -- A reference to the `ApplicationModel.IResourceBuilder`1`.

## Remarks

This overload is not available in polyglot app hosts. Use [DataApiBuilderHostingExtension.AddDataAPIBuilder(IDistributedApplicationBuilder, string, string[])](/reference/api/csharp/communitytoolkit.aspire.hosting.azure.dataapibuilder/dataapibuilderhostingextension/methods.md#adddataapibuilder-idistributedapplicationbuilder-string-string) instead.
