AW: [Mono-devel-list] error BC0000

Please try running the application using xsp.
Try getting some valuable output with mono --trace (check man mono for options), and try limiting your point of failure with this. If you insist on using mod_mono, build mod_mono from source, passing the --enable-debug option to the autogen / configure script...Output is logged to /var/log/apache2/error.log

What I mean is, call xsp as follows: mono --trace=[options_go_here] /path/to/xsp.exe

Hope that helps to locate the issue....

Are you using XSP or Apache (Version?) with mod_mono?

Hi All,

I try to run an ASP.NET webapplication (compiled with MS Visual Studio, Windows XP Professional, code behind structure) on a Linux machine (SuSE 9.2) using Mono 1.1.8. The application is quite heavy weight so there can be several sources of errors but I can not now where to start to fix them. So when I try to run the application I get the following error page:

Server Error in '/dms' Application
Compilation Error
Description: Error compiling a resource required to service this request. Review your source file and modify it to fix this error. 

Error message: (0,0) : error BC0000: Exception: System.NullReferenceException: Object reference not set to an instance of an object

The application runs fine on Windows IIS 5.1.
