Hi, I'm new to FreeBSD and mono, with some previous experience with MS Dotnet without web related stuff.
Currently I'm on a FreeBSD 7.0 / amd64 system and have installed the mono port with the mono-merge utility. Everyting built without errors and seems to work. When I try monodevelop, the hello world projects for C, C++ and Cs work. Only when I try the Asp.Net example I get into trouble. I have no clue how to resolve the problem. Nonetheless, here is what happens:

With IP address 127.0.0.1:8080 in the Xsp project settings Monodevelop crashes, leaving this error
on the console:

---
Unhandled Exception: GLib.GException: There was an error launching the default action command associated with this location.
  at Gnome.Url.Show (System.String url) [0x00000] 
  at MonoDevelop.Platform.GnomePlatform.ShowUrl (System.String url) [0x00000] 
  at AspNetAddIn.AspNetAppProject.LaunchWebBrowser (System.Object o) [0x00000] 
---

Xsp gives the following message on 127.0.0.1:8080:

---
Server Error in '/' Application

Description: HTTP 500. Error processing request.

Then, after some time, the process disappears from the output of ps -A:
36337  p3  S      0:01.42 /usr/local/bin/mono --debug /usr/local/lib/mono/2.0/xsp2.exe --port 8080 --address 127.0.0.1 --nonstop --verbose



With IP address 0.0.0.0:8080 Monodevelop doesn't crash.

The application output is:

---
xsp2

    Host:          any
    Port:          any

Listening on address: 0.0.0.0
Root directory: /usr/home/daniel/HalloWeb/HalloWeb

---

And a popup message says:

---

Exception occurred: Error: ConnectFailure

Xsp which is obviously running says the following on 127.0.0.1:8080
and 0.0.0.0:8080:

---
Server Error in '/' Application

Description: HTTP 500. Error processing request.

I guess there is something I didn't configure properly. At the moment I don't know how to do it. I'll do a little reading about all this to find a solution. If you think, it's an error / bug, please tell me. I skimmed the bugs in monodevelop's bugzilla but didn't find anything close.

Best
Daniel
