ConverterMigrationHelperMixins class¶

Summary¶

View source

Provides helper methods for migrating converters from Splat to the new ConverterService.

Remarks¶

This class assists with migrating from the legacy Splat-based converter registration to the new ConverterService-based system introduced in ReactiveUI v20.

When to Use:

-

You have existing code that registers converters directly with Splat's IMutableDependencyResolver.

-

You want to preserve existing Splat-registered converters while migrating to the new system.

-

You need to extract converter instances for inspection or manual registration.

Migration Strategies:

• 1.

Automatic (Recommended): Use the ReactiveUIBuilder.WithConvertersFrom() method to automatically import all Splat-registered converters during application initialization.

• 2.

Manual Extraction: Use ExtractConverters to get all converters from Splat, then inspect or register them manually.

• 3.

Direct Import: Use ImportFrom to import converters directly into an existing ConverterService instance.

Examples¶

Example 1: Automatic migration via builder (recommended)

// Import all existing Splat-registered converters automatically
 RxAppBuilder.CreateReactiveUIBuilder()
 .WithConvertersFrom(AppLocator.Current)
 .WithConverter(new AdditionalConverter()) // Add new converters
 .BuildApp();

Example 2: Manual extraction and inspection

// Extract converters for inspection
 var (typed, fallback, setMethod) = ConverterMigrationHelperMixins.ExtractConverters(AppLocator.Current);
 
 Console.WriteLine($"Found {typed.Count} typed converters");
 Console.WriteLine($"Found {fallback.Count} fallback converters");
 Console.WriteLine($"Found {setMethod.Count} set-method converters");
 
 // Register them individually if needed
 var converterService = new ConverterService();
 foreach (var converter in typed)
 {
 converterService.TypedConverters.Register(converter);
 }

Example 3: Direct import into existing service

var converterService = RxConverters.Current;
 converterService.ImportFrom(AppLocator.Current);
