Description Tim Banchi 2014-03-05 08:38:24 UTC
If a backslash exists in the username (eg when likewise-open is used) a Compiler Error occurs:

Compiler Error Message: CS0006: Metadata file `/tmp/<domain/>/<username/>-temp-aspnet-0/5ed74d00/App_global.asax_34cccb99.dll' could not be found
/Default.aspx

Version information: Mono Runtime Version: 2.10.8.1 (Debian 2.10.8.1-5ubuntu2); 
ASP.NET Version: 4.0.30319.1
Distribution: Ubuntu 13.10 32bit

most likely reason for the bug: 
the backslash in the username is translated into a forward slash when looking for the dll in the tmp directory

reproduce bug:
1) login with a user which has a backslash in its username (eg likewise-open creates a username consisting of <domain/>\<username/>)
2) in monodevelop create empty C# ASP.NET Web Application
3) compile and run 
--> Comilation Error:
Server Error in '/' Application

Please upgrade to recent mono, preferably 3.2.8 or newer and test it again
Comment 2 Tim Banchi 2014-03-05 09:17:44 UTC
Hello Marek,

I updated to 3.2.8 and still the same issue. 

I get:
System.Web.Compilation.CompilationException
CS0006: Metadata file `/tmp/<domain/>/<username/>-temp-aspnet-0/63b7d575/App_global.asax_bf3eb0e.dll' could not be found

Details: CS0006: Metadata file `/tmp/<domain/>/<username/>-temp-aspnet-0/63b7d575/App_global.asax_bf3eb0e.dll' could not be found

bypass bug:
Again, if I copy the compiled dlls to the directory without backslash:
cp -R <domain/>\\<username/>-temp-aspnet-0/63b7d575/ <domain/>/<username/>-temp-aspnet-0/

the application works.
