eQuantic.Validation.AspNetCore

ASP.NET Core integration for eQuantic.Validation, supporting Minimal APIs and MVC in .NET 8 and .NET 10.

dotnet add package eQuantic.Validation.AspNetCore

Quick Start

  1. Register validators in your Program.cs (AddValidator registers the validation dispatcher automatically; the names avoid colliding with .NET 10's built-in AddValidation):
builder.Services.AddValidator<CreateOrder, CreateOrderValidator>();
  1. For Minimal APIs, apply the endpoint filter. Rules run sequentially by default; parallel execution is opt-in and requires concurrency-safe rule dependencies:
app.MapPost("/orders", (CreateOrder command) => Results.Ok())
   .RequireValidation("create");

app.MapPost("/quotes", handler)
   .RequireValidation(ValidationExecutionMode.Parallel);
  1. For MVC Controllers, enable the global validation action filter:
builder.Services.AddControllers().AddValidationFilter();
  1. Enable OpenAPI 3.1 schema transformations and per-request localization (combine with UseRequestLocalization so Accept-Language drives the culture):
builder.Services.AddValidationLocalization<ValidationResources>();
builder.Services.AddOpenApi(options =>
{
    options.AddValidationTransformer();
});

Failed validation requests automatically return HTTP 400 with RFC 7807 / RFC 9457 ValidationProblemDetails. The errors dictionary maintains ASP.NET Core client compatibility, while extensions.issues provides structured code, path, and severity (emitted as JSON nodes, safe for source-generated serialization and Native AOT):

{
  "title": "One or more validation errors occurred.",
  "status": 400,
  "errors": { "Email": ["Email must be a valid email address."] },
  "issues": [
    { "path": "Email", "code": "customer.email.invalid", "message": "Email must be a valid email address.", "severity": "Error" }
  ]
}

Warnings on successful responses

Valid requests with Severity.Warning failures respond 200 with a Validation-Warnings header (path:code pairs). The full failures are available to the handler:

app.MapPut("/profile", (UpdateProfile request, HttpContext http) =>
{
    var warnings = ValidationWarnings.GetWarnings(http);
    return Results.Ok(new { saved = true, warnings });
}).RequireValidation();

Async rule deduplication

The filters create one validation context per request with async-rule deduplication enabled: the same MustAsync for the same instance and value (composed validators, duplicated collection elements, revalidation) performs its I/O once per request. No configuration needed.
