# SaifValidationException

Exception thrown to signal a validation failure, optionally carrying a full `IValidationResult` so callers can surface all failures rather than a single message. ([BR-044](../../business-rules.md#br-044-a-saifvalidationexception-always-exposes-a-non-null-ivalidationresult))

## Purpose
- Exception thrown to signal a validation failure, optionally carrying a full `IValidationResult` so callers can surface all failures rather than a single message. ([BR-044](../../business-rules.md#br-044-a-saifvalidationexception-always-exposes-a-non-null-ivalidationresult))

## Context
- Namespace: `SAIF.Common`
- Assembly/package: `SAIF.Framework.Common`

| SaifValidationException() | `public SaifValidationException()` | Parameterless constructor. |
| SaifValidationException(IValidationResult validationResult) | `public SaifValidationException(IValidationResult validationResult)` | Constructs the exception carrying a pre-built validation result.
