[Mono-list] System.InvalidOperationException while trying out Webforms project on Mac (Mono)

[Christian Schmitt]

Hello, currently I’m trying out Mono on Mac OS X and later on Linux since we are trying to make our project runnable on these systems however we got a strange error:
System.InvalidOperationException

With the following stack trace:

Exception stack trace:
  at System.Web.HttpApplication+<Pipeline>c__Iterator1.MoveNext () [0x00df2] in /private/tmp/source-mono-mac-4.0.0-branch-c5sr2/bockbuild-mono-4.0.0-branch/profiles/mono-mac-xamarin/build-root/mono-4.0.2/mcs/class/System.Web/System.Web/HttpApplication.cs:1329 
  at System.Web.HttpApplication.Tick () [0x00000] in /private/tmp/source-mono-mac-4.0.0-branch-c5sr2/bockbuild-mono-4.0.0-branch/profiles/mono-mac-xamarin/build-root/mono-4.0.2/mcs/class/System.Web/System.Web/HttpApplication.cs:915 

Currently that looks like internal code so I don’t know what to do, any advise?
