As there was no feedback in the EAP forum for several days i repost this here:
While working on my VB project i did a rename refactoring on a protected method (a Sub). I just changed the capitalization of the method name to fullfill my coding standards (specially i just changed the first letter of the method name to uppercase). This change was not reflected in the code. All calls of the method are with first letter lowercase.
I remember this was an issue in the 5.x EAP and works in 6.x.
