v2.1.0

New stuff / changes

• It is now possible to configure CorrelatorHttpMessageHandler separately, so you can use different header when talking to specific (legacy) service
• Breaking CorrelatorOptions.ReadFrom is List<string> now - that means order of values matters - you now have better control over reading header value
• Breaking CorrelatorHttpMessageHandler constructor requires PropagationSettings instead of IOptions<CorrelatorOptions>

v2.0.1

New features

New components

• Introducing CorrelationContext as container for current CorrelationId with additional information about HTTP header (when correlation received)
• Introducing ICorrelationContextAccessor for accessing current correlation context
• Introducing ICorrelationContextEmitter for returning (emitting) CorrelationId back to caller
• Possibility to provide own implementations of:
  • ICorrelationContextFactory for reading correlation from HttpContext
  • ICorrelationEmitter for returning correlation back to caller (handy when correlation ID is generated)

Options

• Option to preserve HttpContext.TraceIdentifier

Other

• Support for structured logging
• Targeting both netstandard2.1 and netstandard2.0
• ...
• Starting with 2.0.1 as I screwed up version of pre-release package

Breaking changes

Configuration

• Configure with AddCorrelator() requires additional steps registering ICorrelationContextFactory and ICorrelationEmitter, new extension AddDefaultCorrelator introduced for simple configuration

Options

• HttpContext.TraceIdentifier is preserved by default (correlation ID won't overwrite trace identifier, you can access correlation via accessor; optionally you can configure Correlator to replace TraceIdentifier)
• Options.Factory changed from Func<CorrelationId> to Func<HttpContext, CorrelationId>?
• PropagationSettings.KeepIncomingHeaderName changed from property to static method where you can provide fallback header name

Namespace changes

• IServiceCollection extensions (AddCorrelation, ...) moved under W4k.AspNetCore.Correlator.Extensions.DependencyInjection namespace
• IHttpClientBuilder extension (WithCorrelation) moved under W4k.AspNetCore.Correlator.Extensions.DependencyInjection
  namespace
• CorrelatorHttpMessageHandler moved under W4k.AspNetCore.Correlator.Http namespace

Structural changes

• CorrelationId changed from struct to class
• CorrelatorHttpMessageHandler is now sealed

• Improved dependency injection and configuration of HTTP message handler
