Update dll created in C#

Hi,

I've created dll library in VS and added project to ax2012 AOT. In Ax i can use this dll and it works fine, now i've added few methods in this dll, rebuild project and deployed to AX. In Morphix inteli sense i can see my new methods but when i try to use them i've got an error with message that my new method can't by found in assembly. Can someone tell me how to refresh assemblies in AX?
