How to call axapta method in Visual Studio without BusinessConnector ?

Any other way to call axapta method in Visual Studio.

I don’t want to use BusinessConnector DLL and Enterprise Portal stuffs.

Can we create simple web application or web service and can call axapta methods ?

Business Connector is the only way how to call code in AX2009 from external applications. You can publish AIF document services as web services (see AX 2009 AIF Web Services Screencast), nevertheless IIS still uses Business Connector to communicate with AX.
