Mono 3.0/Debian/asp.net - Method not found: 'System.Configuration.IConfigurationSectionHandler.Create

Question

Debian Sid, Mono 3.0. I'm trying to run mvc application (it worked before upgrading mono to 3.0). This is exception thrown:

Exception caught during reading the configuration file:
System.MissingMethodException: Method not found: 'System.Configuration.IConfigurationSectionHandler.Create'.
  at System.Configuration.ClientConfigurationSystem.System.Configuration.Internal.IInternalConfigSystem.GetSection (System.String configKey) [0x00000] in <filename unknown>:0 
  at System.Configuration.ConfigurationManager.GetSection (System.String sectionName) [0x00000] in <filename unknown>:0 
  at System.Configuration.ConfigurationManager.get_AppSettings () [0x00000] in <filename unknown>:0 
  at Mono.WebServer.Apache.Server.get_AppSettings () [0x00000] in <filename unknown>:0 
  at Mono.WebServer.Apache.Server+ApplicationSettings..ctor () [0x00000] in <filename unknown>:0 

I've also found tip to make change in /usr/bin/mod-mono-server4 from:

#!/bin/sh
exec /usr/bin/mono $MONO_OPTIONS "/usr/lib/mono/4.0/mod-mono-server4.exe" "$@"

To:

#!/bin/sh
exec /usr/bin/mono $MONO_OPTIONS "/usr/lib/mono/4.5/mod-mono-server4.exe" "$@"

Unfortunatelly, there is no such file: /usr/lib/mono/4.5/mod-mono-server4.exe (no such file in /usr/lib/mono/4.5/ directory).

Do you have any ideas what's wrong? My application is ServiceStack simple webpage and it works on mono 2.10. But it doesn't work anymore after upgrade to 3.0.

Answer 1

You need to add a symbolic link for that file

# ln -s /usr/lib/mono/4.0/mod-mono-server4.exe /usr/lib/mono/4.5/mod-mono-server4.exe

That way it will still use mod-mono-server4.exe but with the 4.5 dll's
