Z.ExtensionMethods is a C# library that enhances .NET Framework and .NET Core with over 1000 extension methods covering types like String, DateTime, Stream, FileInfo, and many more. It is distributed on NuGet in several packaging variants and is backed by a documented cheat sheet and online examples.

Use cases

• find c# extension methods for string manipulation
• extension methods library for .net core
• c# helper methods for datetime and files
• add missing utility methods to .net built-in types
• c# extension methods cheat sheet
• nuget package with common c# extension methods

When to choose

• you want a broad, batteries-included set of ready-made C# extension methods instead of writing your own helpers
• you need an MIT-licensed NuGet utility library that works on both .NET Framework and .NET Core
• you want documented, searchable extension methods with online examples for learning C# idioms

When to avoid

• you prefer minimal dependencies and only need one or two specific helpers
• you are not developing in C# or on the .NET platform
• you need a focused single-purpose library rather than a large grab-bag of methods
