Source and precompiled test example

User-Agent:       Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.0;
Trident/4.0; SLCC1; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729)

The error 'No @webservice directive found' is returned as a 500 Internal Server
Error when a webservice is accessed from a client-side proxy for a precompiled
web application. Calls to webservice methods on the class from the browser
subsequently fail.

Reproducible: Always

Steps to Reproduce:
1. Create new ASP.NET web site in VS.NET.
2. Add a new web service to the project.
3. Add a project reference to 'System.Web.Extensions'.
4. Add a reference to System.Web.Script.Services in the webservice and mark the
class with the 'ScriptService' attribute.
4. In the Default.aspx page add a ScriptManager control and add a
ServiceReference to the webservice.
5. Add Javascript to call a method on the webservice e.g during window.onload.
6. Precompile using aspnet_compiler.
7. Copy to Mono environment and run with xsp2.
8. Browse to Default.aspx.
Actual Results:  
The webservice file fails to load with the server returning a 500 Internal
Server Error with the following error message:

Description: HTTP 500. Error processing request.

Version information: Mono Version: 2.0.50727.1433; ASP.NET Version:
2.0.50727.1433 

This results in a 'xxxclass is not defined' Javascript error in the client
browser when a webservice method is called.

Expected Results:  
Asmx file loaded correctly from aspx and webservice method call succeeded. 

It appears that the System.Web.UI.SimplWebHandlerParser.GetDirectivesAndContent
method attempts to find a '@webservice' directive in the precompiled asmx file
which of course only contains 'Content:This is a marker file generated by the
precompilation tool, and should not be deleted!'. Consequently it fails to find
the directive and a ParseException is thrown.
