Runtime IL-Rewriting can be used to add behavior such as logging to applications, or redirect calls from one API to another. This article and accompanying source code explains how to substitute a method call at runtime.
#include "stdafx.h"

using namespace System;
using namespace System::Reflection;
using namespace System::Runtime::CompilerServices;
using namespace System::Runtime::InteropServices;
using namespace System::Security::Permissions;

//
// General Information about an assembly is controlled through the following
// set of attributes. Change these attribute values to modify the information
// associated with an assembly.
//
[assembly:AssemblyTitleAttribute("InterceptApp")];
[assembly:AssemblyDescriptionAttribute("")];
[assembly:AssemblyConfigurationAttribute("")];
[assembly:AssemblyCompanyAttribute("Microsoft")];
[assembly:AssemblyProductAttribute("InterceptApp")];
[assembly:AssemblyCopyrightAttribute("Copyright (c) Microsoft 2012")];
[assembly:AssemblyTrademarkAttribute("")];
[assembly:AssemblyCultureAttribute("")];

//
// Version information for an assembly consists of the following four values:
//
//      Major Version

// by using the '*' as shown below:

[assembly:AssemblyVersionAttribute("1.0.*")];

[assembly:ComVisible(false)];

[assembly:CLSCompliantAttribute(true)];

[assembly:SecurityPermission(SecurityAction::RequestMinimum, UnmanagedCode = true)];
