How to overload a web method in ASP.NET webservice...?

Here is the solution to overload a web method in web service...

First of all, make changes in this:

[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]

You need to write like this:

[WebServiceBinding(ConformsTo = WsiProfiles.None)]

Then make changes in webmethod.
Add messageName property to your webmethod:

[WebMethod (MessageName="YourMessageName")]

After doing this, your webmethod will now be overloaded and no error will arise.

Enjoy...
