Server Error in '/WebService1' Application.

I am new to ASP.Net and just starting out with web services so this is a newbie question.  I am trying to test out a simple web service and am able to get it to run if I go through the description of the web service "http://localhost/WebService1/Service1.asmx?op=HelloWorld" and click the invoke button but when I have a new browser window and type in the exact same url when I click invoke I get a "Server Error in '/WebService1' Application." error.  This URL is "http://localhost/WebService1/Service1.asmx/HelloWorld" The full error and the code for the web service is listed below:

Request format is unrecognized.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.InvalidOperationException: Request format is unrecognized.

Source Error:

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

    ' To build, uncomment the following lines then save and build the project.
    ' To test this web service, ensure that the .asmx file is the start page
    ' and press F5.
    '
    <WebMethod()> _
    Public Function HelloWorld() As String
        Return "Hello World"
    End Function

End Class


Any help for this beginner question would be very appreciated.
