Question

I have Ninject configured to do DI in an ASP.NET MVC 3 application. This is working fine and it injects the proper classes in to my controllers.

When I try and add Ninject.Extensions.Interception to work with my application I start getting an ambiguous match exception. This only happens when I add the Ninject.Extensions.Interception.DynamicProxy assembly. If I remove this assembly then it runs fine again. I also have referenced Ninject.Extensions.Intereception and Castle.Core.

Note that I have not configured interception in the application. I am just adding a reference and this error starts happening.

I am using Ninject 2.2.1.0 and Ninject.Extensions.Interception 2.2.0.0.

private const BindingFlags DefaultBindingFlags =
    BindingFlags.Public |
    BindingFlags.NonPublic |
    BindingFlags.Instance;

public static PropertyInfo GetPropertyFromMethod( this MethodInfo method, Type implementingType )
{
    if ( !method.IsSpecialName )
    {
        return null;
    }

    return implementingType.GetProperty( method.Name.Substring( 4 ), DefaultBindingFlags );
}
