MethodBase.Invoke virtual dispatch

This is a convenience method that calls the <xref:System.Reflection.MethodBase.Invoke%28System.Object%2CSystem.Reflection.BindingFlags%2CSystem.Reflection.Binder%2CSystem.Object%5B%5D%2CSystem.Globalization.CultureInfo%29> method overload, passing <xref:System.Reflection.BindingFlags.Default> for `invokeAttr` and `null` for `binder` and `culture`.

This says Invoke(Object, Object[]) is just forwarder to Invoke(Object, BindingFlags, Binder, Object[], CultureInfo). Example section have this text

The following code example demonstrates dynamic method lookup using reflection. Note that you cannot use the <xref:System.Reflection.MethodInfo> object from the base class to invoke the overridden method in the derived class, because late binding cannot resolve overrides.

Invoke(Object, BindingFlags, Binder, Object[], CultureInfo) remarks section contradicts it and says it actually does virtual dispatch.

Reflection uses dynamic method lookup when invoking virtual methods. For example, suppose that class B inherits from class A and both implement a virtual method named M. Now suppose that you have a `MethodInfo` object that represents M on class A. If you use the `Invoke` method to invoke M on an object of type B, then reflection will use the implementation given by class B. Even if the object of type B is cast to A, the implementation given by class B is used (see code sample below).

For example, if the method reflected by this instance is declared as `public boolean Compare(String a, String b)`, then `parameters` should be an array of `Objects` with length 2 such that `parameters[0] = new Object("SomeString1") and parameters[1] = new Object("SomeString2")`.

new Object("SomeString2") is invalid construct.

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.
