Issue Stats Issue Stats

A collection of libraries intended to contain all P/Invoke method signatures for popular operating systems. Think of it as http://pinvoke.net, but proven to compile and work properly, and often with sample usage in the form of unit tests.

Each library is exposed as its own NuGet package, and may include .NET Portable libraries as applicable, exposing those APIs that are available only on Desktop, or Store, or both as appropriate.

Usage

Install the NuGet package(s) for the DLLs you want to P/Invoke into. For example, if you want to P/Invoke into Win32's BCrypt.dll, install this package:

Install-Package PInvoke.BCrypt

Then import the following namespaces, as demonstrated below (if using C# 6):

using PInvoke;
using static PInvoke.BCrypt; // Supported in C# 6 (VS2015) and later.

This will allow you to conveniently call these methods directly by method name:

var error = BCryptOpenAlgorithm(AlgorithmIdentifiers.BCRYPT_SHA256_ALGORITHM); // C# 6 syntax
var error = BCrypt.BCryptOpenAlgorithm(BCrypt.AlgorithmIdentifiers.BCRYPT_SHA256_ALGORITHM); // C# 5 syntax

Sometimes a PInvoke method may have multiple overloads. For example every method that accepts struct* parameters has an overload that accepts IntPtr in its place. In other cases there may be overloads that accept struct* and struct?. In some of these cases that can lead to compiler errors if you pass in null because both struct* and struct? overloads can match. To resolve the issue, add a cast to your null: (struct?)null to resolve the ambiguity.

Design goals

Provide a slightly higher than lowest level API for P/Invoke signatures. For example, instead of IntPtr parameters and uint flags, you'll see SafeHandle-derived types as parameters and flags enum types. API documentation will be provided via XML doc comments for easy reading with Intellisense, along with links to the describing pages on MSDN or elsewhere as applicable.

Distribution

This library should be available on NuGet for easy consumption by your projects. You may also copy and paste the P/Invoke signatures you need directly into your projects if desired.
