The library provides an abstraction over IoC containers and service locators. Using the library allows an application to indirectly access the capabilities without relying on hard references.

CommunityToolkit.HighPerformance by: Microsoft

This package includes high performance .NET helpers such as: - Memory2D<T> and Span2D<T>: two types providing fast and allocation-free abstraction over 2D memory areas. - ArrayPoolBufferWriter<T>: an IBufferWriter<T> implementation using pooled arrays, which also supports IMemoryOwner<T>. - MemoryBufferWriter<T>: an IBufferWriter<T>: implementation that can wrap external Memory<T>: instances. - MemoryOwner<T>: an IMemoryOwner<T> implementation with an embedded length and a fast Span<T> accessor. - SpanOwner<T>: a stack-only type with the ability to rent a buffer of a specified length and getting a Span<T> from it. - StringPool: a configurable pool for string instances that be used to minimize allocations when creating multiple strings from char buffers. - String, array, Memory<T>, Span<T> extensions and more, all focused on high performance. - HashCode<T>: a SIMD-enabled extension of HashCode to quickly process sequences of values. - BitHelper: a class with helper methods to perform bit operations on numeric types. - ParallelHelper: helpers to work with parallel code in a highly optimized manner. - Box<T>: a type mapping boxed value types and exposing some utility and high performance methods. - Ref<T>: a stack-only struct that can store a reference to a value of a specified type. - NullableRef<T>: a stack-only struct similar to Ref<T>, which also supports nullable references.

CommunityToolkit.Mvvm by: Microsoft

This package includes a .NET MVVM library with helpers such as: - ObservableObject: a base class for objects implementing the INotifyPropertyChanged interface. - ObservableRecipient: a base class for observable objects with support for the IMessenger service. - ObservableValidator: a base class for objects implementing the INotifyDataErrorInfo interface. - RelayCommand: a simple delegate command implementing the ICommand interface. - AsyncRelayCommand: a delegate command supporting asynchronous operations and cancellation. - WeakReferenceMessenger: a messaging system to exchange messages through different loosely-coupled objects. - StrongReferenceMessenger: a high-performance messaging system that trades weak references for speed. - Ioc: a helper class to configure dependency injection service containers.

dbup by: Paul Stovell, Jim Burger, Jake Ginnivan, Damian Maclennan

This package exists to allow easy upgrades from pre-4.0 version This package was split into two packages dbup-core and dbup-sqlserver so that non SQL Server packages did not need to also reference the SQL Server code. Uninstall this package and install dbup-sqlserver, or the package for the server(s) you are targeting instead!

dbup-core by: Paul Stovell, Jim Burger, Jake Ginnivan, Damian Maclennan

DbUp makes it easy to deploy and upgrade SQL Server databases by running change scripts. This is the core library and should be used in conjunction with the database specific package (eg dbup-sqlserver, dbup-mysql)

dbup-postgresql by: https://github.com/orgs/DbUp/people

DbUp makes it easy to deploy and upgrade SQL Server databases. This package adds PostgreSQL support.

dbup-sqlserver by: https://github.com/orgs/DbUp/people
