LegacyWrapper 3.0 is a major rewrite and not backwards compatible to prior versions.

See this blog post for details.

  • The old Invoke<TDelegate>() method has been replaced by a much simpler and more type-safe pattern:
// Define a proxy interface with matching method names and signatures
// The interface must be derived from IDisposable!
[LegacyDllImport("User32.dll")]
public interface IUser32Dll : IDisposable
{
    [LegacyDllMethod(CallingConvention = CallingConvention.Winapi)]
    int GetSystemMetrics(int nIndex);
}

// Create configuration
IWrapperConfig configuration = WrapperConfigBuilder.Create()
        .TargetArchitecture(TargetArchitecture.X86)
        .Build();

// Create new Wrapper client providing the proxy interface
// Remember to ensure a call to the Dispose()-Method!
using (var client = WrapperProxyFactory<IUser32Dll>.GetInstance(configuration))
{
    // Make calls - it's that simple!
    int x = client.GetSystemMetrics(0);
    int y = client.GetSystemMetrics(1);
}

Therefore, there is no longer the need to:

  • Create a delegate
  • Cast result values
  • Pass function parameters as array of object
  • Supply the method name as magic string

Other things that changed:

  • Documentation on classes and methods has been improved
  • There are more unit tests now (especially edge cases)
