I have recently upgraded my opensuse machine from 12.2 to Leap 42.1 (x86_64). It's mostly going well. However, I installed mono & xsp via yast (KDE) and I have found that both xsp & fastcgi-mono-server4 are unwell.

If I ask these modules (mono, xsp & fastcgi-mono-server4) for their version numbers, this is what I get back:-

 #mono -V

    #xsp -V
Exception caught during reading the configuration file:

XSP server is a sample server that hosts the ASP.NET runtime in a

    [ERROR] FATAL UNHANDLED EXCEPTION: System.InvalidProgramException: Invalid IL code in System.Xml.XmlDocument:GetElementsByTagName (string): IL_0000: ret

      at Mono.WebServer.FastCgi.Server.Main (System.String[] args) [0x00000] in <filename unknown>:0

I notice that the mono Architecture is amd64, where I'm expecting x86_64.

And of course both xsp & fastcgi-mono-server4 complain about unhandled exceptions.

Does anyone know want I can do to fix this?

Thanks in advance

I have resovled this issue.

I installed xsp via yast & zypper several times without improvment. Finally, I tried installing directly from

https://software.opensuse.org/package/xsp

This has made the crital difference for me - fastcgi-mono-server4 no longer complains about unhandled exceptions. However, xsp still does. But given that I don't really want xsp, it doesn't worry me.

My nginx <> fast-mono-server4 <> asp.net web server is WORKING!

Now to do something clever with it...
