v0.73.3933

• New: Configure JSON serialization:

  EventFlowOptions.New.
    .ConfigureJson(json => json
      .AddSingleValueObjects()
      .AddConverter<SomeConverter>()
    )

• New: ASP.NET Core enhancements:
  • New fluent configuration API for ASP.NET Core components:
    services.AddEventFlow(o => o.AddAspNetCore(c => {...})); (old syntax
    AddAspNetCoreMetadataProviders is now deprecated).
  • .RunBootstrapperOnHostStartup() runs bootstrappers together with ASP.NET
    host startup. Previously, this was done in AddAspNetCoreMetadataProviders
    and led to some confusion.
  • .UseMvcJsonOptions() adds EventFlow JSON configuration (see below) to ASP.NET Core,
    so you can accept and return Single Value Objects as plain strings for example.
  • .Add{Whatever}Metadata() configures specific metadata provider.
  • .AddUserClaimsMetadata(params string claimTypes) configures the new claims metadata
    provider (for auditing or "ChangedBy" in read models).
  • .UseLogging() configures an adapter for Microsoft.Extensions.Logging
  • .UseModelBinding() adds model binding support for Single Value Objects:

        [HttpGet("customers/{id}")]
        public async Task<IActionResult> SingleValue(CustomerId id)
        {
            if (!ModelState.IsValid)
            {
                return BadRequest(ModelState);
            }

• Fix: ASP.NET Core AddRequestHeadersMetadataProvider doesn't throw when
  HttpContext is null.
• Fix: ReadModelRepopulator now correctly populates IAmAsyncReadModelFor
