ASPNet Wrapper for ExtJS 4 WebServices

Eden Ridgway has created an ASP.NET Ajax Web Services proxy for ExtJS 3 and I like that because it allows developer to use ASP.NET Web Service references and dont need to write url directly in there. Anyway, the code does not work anymore for ExtJS v. 4, because Sencha has changed their implementation a lot and there are some breaking changes. For example old Ext.data.HttpProxy is just an alias to a different class and above all, the class inheritance is changed a lot. More about this here
