Never write another custom exception class ever again.❌

EZXception

EZXception is a netstandard2.0 library that ships 50+ pre-built, richly structured exception types covering every scenario a .NET developer encounters - validation, authorization, data access, business rules, configuration, external services, file I/O, networking, serialization, concurrency, and domain modeling.

Instead of writing this every time:

publicclassUserNotFoundException:Exception{publicUserNotFoundException(stringid):base($"User '{id}' was not found."){}}

You just do this:

thrownewEntityNotFoundException("User",id);

Every exception carries typed contextual properties (entity name, field name, status code, timeout, etc.) so catch blocks can read structured data instead of parsing message strings.

Get Started

dotnet add package EZXception --version 1.0.0

Naming Notes

Three exceptions carry an EZ prefix to avoid compile-time ambiguity with identically named BCL types:

EZXception type	Would shadow
EZXception.IO.EZFileNotFoundException	System.IO.FileNotFoundException
EZXception.IO.EZDirectoryNotFoundException	System.IO.DirectoryNotFoundException
EZXception.Serialization.EZSerializationException	System.Runtime.Serialization.SerializationException
