EventFlow.AspNetCore 0.73.3933

• .NETStandard 2.0

  • EventFlow (>= 0.73.3933)
  • Microsoft.AspNetCore.Http (>= 2.0.0)
  • Microsoft.AspNetCore.Mvc.Formatters.Json (>= 2.0.0)
  • Microsoft.Extensions.Hosting.Abstractions (>= 2.1.0)

New: Configure JSON serialization:
```csharp
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:
```csharp
[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`
