Web Service will not delete file

I am creating an ASP.NET Web Service and I am trying to do something very basic... delete a file. The code is simple:

//test code
string testFilePath = @"C:\Test\Test.zip";

if(File.Exists(testFilePath))    //it sees the file just fine
    File.Delete(testFilePath);  // then throws an exception... why?

I get an error that states: "Request format is unrecognized."

The same exact code will work perfect in a windows app, but not in this web service... why?

Do you have impersonation set to True in the web.config for the service?

Usually the error is "Access is denied" when trying to perform this kind of operation.
