The application's configuration files must contain 'trust' section

[Guest]

HI,

I have created Webservice project in Visual Studio 2005, by default it is
created the Service.asmx file with the code as

[WebMethod]
public string HelloWorld() {
return "Hello World";
}

I tried to build this project, but it is giving compilation error
"The application's configuration files must contain 'trust' section."

Please send me the solution how to solve this problem.

Thank s in advance.
