Bump Foundatio.Mediator.Abstractions from 1.2.1 to 1.3.0

[dependabot]

Updated Foundatio.Mediator.Abstractions from 1.2.1 to 1.3.0.

Release notes

Sourced from Foundatio.Mediator.Abstractions's releases.

1.3.0

Breaking Changes

• [HandlerEndpoint(SuccessStatusCode = …)] → SuccessStatusCodes (#​199) — the singular SuccessStatusCode (int) property was replaced with the plural SuccessStatusCodes (int[]). Update any usages.

Features

• Endpoint success metadata & result-mapping options (#​199) — Success result factories (Result.Created(), Result.Accepted(), Result.NoContent()) are detected and emit matching response metadata. Adds MediatorResultMapperOptions<TResult> plus DI/builder helpers to override specific ResultStatus → HTTP mappings without replacing the whole mapper (full IMediatorResultMapper<IResult> replacement is still supported). Result.Invalid() keeps ASP.NET Core's default ValidationProblem behavior.
• Endpoint content-type metadata (#​200) — AcceptsContentTypes and ProducesContentTypes on [HandlerEndpoint] generate .Accepts<T>(...) / .Produces<T>(...) OpenAPI metadata.
• Explicit route-template parameter binding (#​232) — A {placeholder} in an explicit [HandlerEndpoint(..., "Path/{param}")] template now binds from the route regardless of property naming or HTTP method. Previously the value was emitted as [FromQuery], so path-only requests (e.g. GET /contracts/H-42) returned 400.
• Form / file upload endpoints (#​233) — Handlers whose message exposes IFormFile, IFormFileCollection, or IFormCollection now generate multipart/form-data endpoints. File properties bind by name, other fields bind via [FromForm], route placeholders still bind from the route. Antiforgery (CSRF) validation stays required by default — disable it explicitly per endpoint with [HandlerEndpoint(DisableAntiforgery = true)] or assembly-wide with [assembly: MediatorConfiguration(EndpointDisableAntiforgery = true)].
• Exclude handlers by namespace — new HandlerExcludeNamespacePatterns on [assembly: MediatorConfiguration] excludes handlers in matching namespaces from generation and discovery (exact match or trailing-wildcard prefix, e.g. "MyCompany.Messaging.*").

Dependencies

• Numerous dependency updates, including WolverineFx (5.31.1 → 6.3.2), MassTransit (9.0.1 → 9.1.1), Immediate.Handlers, Scalar.AspNetCore, Scriban, Verify.XunitV3, and the Microsoft.Extensions.* / Microsoft.AspNetCore.* packages. See the full changelog.
