Property Change Notification

This library offers the PropertyChangeNotifier class, which you may inherit from to quickly get all the property utilities we're all tired of copying and pasting everywhere. Just call the protected OnPropertyChanged and OnPropertyChanging methods at the appropriate times from setters and compiler services will figure out what property you're in. Or, if all you need to do is set the value of a field, SetBackedProperty couldn't make it any easier or convenient to handle that as efficiently as possible. DynamicPropertyChangeNotifier is also available if your class needs to be dynamic.

Be sure to set the protected Logger property if you want the abstract class to log what's going on with property change notification.

Disposal

This library features base classes that handle things we've written a thousand times over, this time involving disposal. If you want to go with an implementation of the tried and true IDisposable, just inherit from SyncDisposable. Want a taste of the new IAsyncDisposable? Then, inherit from AsyncDisposable. Or, if you want to support both, there's Disposable. Additionally, if your object needs to be dynamic, you can use DynamicSyncDisposable, DynamicAsyncDisposable, or DynamicDisposable. Each of these features abstract methods to actually do your disposal. But all of the base classes feature:

• proper implementation of the finalizer and use of GC.SuppressFinalize
• monitored access to disposal to ensure it can't happen twice
• the ability to override or "cancel" disposal by returning false from the abstract methods (e.g. you're reference counting and only want to dispose when your counter reaches zero)
• a protected ThrowIfDisposed method you can call to before doing anything that requires you haven't been disposed
• an IsDisposed property the value (and change notifications) of which are handled for you

This library provides the IDisposalStatus interface, which defines the IsDisposed property and all the base classes implement it. This library also provides the INotifyDisposing, INotifyDisposed, and INotifyDisposalOverridden interfaces, which add events that notify of these occurrences.

Be sure to set the protected Logger property if you want the abstract class to log what's going on with disposal.

Reflection

This library has useful tools for when you can't be certain of some things at compile time, such as types, methods, etc. While .NET reflection is immensely powerful, prior to .NET 7, it's not very quick. To address this, this library offers the following extension methods which will emit IL, generate delegates, and cache them for expedited use of Reflection:

• ConstructorInfo.FastInvoke: call a constructor only known at runtime quickly
• MethodInfo.FastInvoke: call a method only known at runtime quickly
• PropertyInfo.FastGetValue: get the value of a property only known at runtime quickly
• PropertyInfo.FastSetValue: set the value of a property only known at runtime quickly
• Type.FastDefault: get the default value of a type only known at runtime quickly

Use of these methods in .NET 7 or later will simply call the built-in methods, as they are now optimized.

This library also offers FastComparer and FastEqualityComparer, which implement IComparer and IEqualityComaprer, respectively, but quickly use the methods of Comparer<>.Default and EqualityComaprer<>.Default, respectively, to do their work.

Exceptions

This library provides extension methods for dealing with exceptions:

• GetFullDetails - creates a representation of an exception and all of its inner exceptions, including exception types, messages, and stack traces, and traversing multiple inner exceptions in the case of AggregateException and ReflectionTypeLoadException
