About Existential.NET
Existential is a utility library that 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 (Validate, Maybe<T>)
- log exceptions from an exception filter before they're handled or rethrown
- efficiently resolve Code Analysis issues CA1062 and CA2000
- help generate a hash code, and
- 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 writing text to multiple outputs, converting an IEnumerable to an IEnumerable<T>, getting the name of the current method or negating a Predicate.
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 (3.1.1):
- Minor but high profile formatting fix to package ReadMe.
## In previous version (3.1.0):
**New features:**
- Added support for .Net 8.0
- By default, if exception filter logging fails, a `Trace` message (at `Error` level) will be created instead.
- Added `MultiTextWriter`, a `TextWriter` implementation that can write the same string to multiple outputs.
- Added `IWriteStrategy`, an interface consumed by `MultiTextWriter`.
- Added extension methods for IEnumerable to safely use a non-generic IEnumerator:
- `UsingNonGenericEnumerator(this IEnumerable, Action<IEnumerator>)`
- `UsingNonGenericEnumerator<TResult>(this IEnumerable, Func<IEnumerator, TResult>)`
**Other Improvements:**
- Documentation improvements:
- API documentation reviewed and improved
- Added "exceptions thrown" to documentation throughout
- Updated to DocFX "modern" template
- Migrated test mocks from Moq to NSubstitute
**Deprecated:**
- Marked redundant method as **obsolete**. Will be removed in a future version.
- `TypeExtension.IsInstanceOfType<T>(this T, Type)` - prefer the C# `is` operator
- Removed the deprecated serialisation constructor from ArgumentTypeException for .Net 8.0:
- `ArgumentTypeException(SerializationInfo,StreamingContext)`
