About Existential.NET
Existential is a utility library for dealing with issues such as whether a value exists or not, or whether it exists in the desired form. It contains parameter validation methods, a Maybe monad, and more. Full documentation can be found at existential.ggreig.com.
It can be used to work effectively with nulls, to efficiently resolve Code Analysis issues CA1062 and CA2000, to help generate a hash code, and to convert the names of generic types into a familiar string representation.
It reduces the code you need to write for basic null checks by providing validation techniques or - even better - using the Maybe<T> monad can just help you not to care!
Other classes in Existential help you to avoid constantly reinventing the wheel for common problems such as generating hash codes, safely returning disposable values from methods, and converting an IEnumerable to an IEnumerable<T>.
These solutions aren't innovative in themselves - plenty code examples exist out there - but Existential brings them together into one tested library so you don't have to.

In this version (2.0.0):
========================
Breaking changes:
* Creating a Maybe<T> has been simplfied, with superfluous creation methods removed.
* Removed the following obsolete methods:
* `GetGenericEnumerable.From<T>(IEnumerable)`
* `Maybe.Some<T>(T?)`
* `Maybe.Some<T>(Maybe<T>)`
* `Maybe<T>.op_Implicit(T)`
* `Maybe<T>.Or(Maybe<T>)`
* `Maybe<T>.Or(Func<Maybe<T>>)`
* `Maybe<T>.WithValue(T?)`
* `Maybe<T>.WithValue(Maybe<T>)`
* `Maybe<T>.WithKnownValue(T)`
* `Maybe<T>.WithGuaranteedValue(T)`
New features:
* Added Maybe<T>-supporting extension methods for IEnumerable<T>:
* MaybeSingle<T>(this IEnumerable<T>)
* MaybeSingle<T>(this IEnumerable<T>,Func<T,bool>)
