Entra.EventHandlers 1.2.3

Entra.EventHandlers

Production‑ready implementation layer for Microsoft Entra Authentication Event Handlers. This package builds on top of the MIT‑licensed Entra.EventHandlers.Abstractions and provides fluent response builders, base handler infrastructure, and utilities for constructing custom extensions.

🚀 Features

✔ Fluent Response Builders

Strongly‑typed builders for constructing valid Entra responses:

• AttributeCollectionStartResponseBuilder
• AttributeCollectionSubmitResponseBuilder
• TokenIssuanceStartResponseBuilder
• PrefillValuesBuilder

✔ Unified Entry Point

EntraEventResponses.AttributeCollectionStart();
EntraEventResponses.AttributeCollectionSubmit();
EntraEventResponses.TokenIssuanceStart();

✔ Base Handler Infrastructure

Includes:

• Structured logging
• Correlation scoping
• Execution timing
• Protocol validation (@odata.type)
• Consistent exception handling
• Clean override point (HandleCore)

public class MyStartHandler : AttributeCollectionStartHandlerBase
{
    public MyStartHandler(ILogger<MyStartHandler> logger) : base(logger) {}

    protected override Task<AttributeCollectionStartResponse> HandleCore(
        AttributeCollectionStartEvent request,
        CancellationToken cancellationToken)
    {
        return Task.FromResult(
            EntraEventResponses
                .AttributeCollectionStart()
                .Allow()
                .Build());
    }
}

✔ Prefill Support

return EntraEventResponses
    .AttributeCollectionStart()
    .PrefillValues(p => p
        .With("email", "user@example.com")
        .With("country", "PL"))
    .Build();
