What can I do with Existential.Net?

Work more safely with nulls

Existential.Net provides a couple of ways of dealing with the absence of data.

The static Validate class provides methods that'll throw an exception if data doesn't meet their requirements - most commonly if a null is provided. They're very simple; but fail fast in a controlled manner, and reduce the amount of boiler-plate code required to do so.

Exception filter logging

Methods are provided to support logging exceptions from within exception filters.

Resolve Code Analysis issues

Existential.Net provides functionality that helps to resolve a couple of common Code Analysis issues.

Convert to IEnumerable<T>

Occasionally it's useful to be able to treat a single value as an IEnumerable<T>, or it would have been useful to have an IEnumerable actually be an IEnumerable<T>. Existential.Net provides conversions to enable that.

Work with types

Existential provides a number of other small utility classes; to safely return an instance of IDisposable from a method, to calculate hash codes, to provide the name of the current method (without the need for reflection), and (using reflection) to report the name of a generic type in the form it's usually written.
