Yes it is possible but you have to give different alias name to the web method so that ambiguity can be avoided
---method will be call from application by the name AddInt
[WebMethod Name ="AddInt"]
public void Add(){}//implement code for adding 2 int variable
---------In this step even if you dont give name attribute it will work and method will be called by name Add.
[WebMethod Name ="AddFloat"]
public void Add(){}//implement code for adding 2 float variable
else it will give error  |
