Vanara.Core NuGet Package

Version Build status

This library includes shared methods, structures and constants for use throughout the Vanara assemblies. Think of it as windows.h with some useful extensions. It includes:

  • Extension methods for working with enumerated types (enum), FILETIME, and method and property extractions via reflection
  • Extension and helper methods to marshaling structures arrays and strings
  • SafeHandle based classes for working with memory allocated via CoTaskMem, HGlobal, or Local calls that handles packing and extracting arrays, structures and raw memory
  • Safe pinning of objects in memory
  • Memory stream based on marshaled memory

What is Vanara?

Vanara is a community project that contains various .NET assemblies which have P/Invoke functions, interfaces, enums and structures from Windows libraries. Each assembly is associated with one or a few tightly related libraries.

Issues?

First check if it's already fixed by trying the MyGet build. If you're still running into problems, file an issue.
