I just upgraded to the just released Mono version 4.0.1 on my ubuntu machines. The previous installed version of mono was 3.2.7 (if I remember correctly).
Now the issue:
My first issue is regarding SignalR and self-hosting. I have a .NET 4.5.1 console application in which I self host NancyFx, Web Api and SignalR using OWIN. When running on mono 3.2.7 there was no issues to my knowledge but when I try to start the application on mono 4.0.1 I get the following stack trace:
Unhandled Exception:
System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.InvalidProgramException: Invalid IL code in (wrapper delegate-invoke) <Module>:invoke_callvirt_CancellationTokenRegistration_CancellationToken&_Action`1<object>_object (System.Threading.CancellationToken&,System.Action`1<object>,object): IL_0057: castclass 0x00000007

I have no clue to what this error could mean and I'm greatful for all assistance. I'm using Microsoft ASP.NET SignalR Self Host package version 2.2.0.
And as a side note, I've compiled all my assemblies on the new mono version.
Kind regards,
Simon
This turned out to be a Mono issue which was recently fixed: https://bugzilla.xamarin.com/show_bug.cgi?id=29665

I am using mono v4.2.1 and apache2 in ubuntu 14.04
I managed to install my ASP.NET web service in the url: http://myurl/WebService/Service.asmx
But when I open it, I receive this error:

This is my Service.asmx:
<%# WebService Language="C#" Class="Service" %>
And the Service class is in a library which is added by reference:
using System.Web.Services;
[WebService(Namespace = "http://myurl/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class Service : WebService
{
public Service()
{
}
}
The point is it works completely OK in Microsoft Visual Studio but mono has a problem and I don't know where to look or what to do.
I figured out that it was because the root directory was not correctly set.
I used xsp4 instead of apache2 and it fixed.
ASP.NET MVC3 application is hosted in Apache in Mono as virtual host with address http://www.mysite.com
Requests for files robots.txt , favicon.ico and apple-touch-icon.png cause 404 error below since
there are no MVC3 controllers for those names.
How to server those files ? It it possible to force Apache to serve them as regular files or can we force MVC3 application to return those files ?
Which is proper way to implement this ?
System.Web.HttpException: The controller for path '/robots.txt' was not found or does not implement IController.

Fixing robots.txt:
Right click the project name and select "Add->New Item"
Choose "Text File" and call it "robots.txt"
You can leave this file blank
Fixing favicon.ico:
Go to the RegisterRoutes method of the Global.asax.cs file and add this near the top: You can look at this page for more info: Favicon Icon-MVC3 ASP.NET
routes.IgnoreRoute("{*favicon}", new { favicon = #"(.*/)?favicon.ico(/.*)?" });
Fixing apple-touch-icon.png:
Look at these websites
Why am I getting error for apple-touch-icon-precomposed.png

I did the same thing on a debian and It works fine.
Do you have any suggestions?
Find all your Server.MapPaths and change from
Server.MapPaths(#"\")
to
Server.MapPaths(Path.DirectorySeparatorChar)
Have you checked the paths in your view files? Just as a reminder:
'/' like in <script src="/myScript.js"></script> maps to the DocumentRoot folder defined on your /sites-available/.conf, it may be something like /var/www
'~/' like in <script src="#Url.Content("~/scripts/script1.js")"></script> maps to the path where your mvc application is, it may be somethin like /var/www/site1
'../' would try to access one folder above the DocumentRoot folder. This may actually be forbbiden by your apache site configuration (recommended).
Also note that if your run your mvc app from monodevelop/xspServer the document root and the mvc application path are actually the same but if you install your mvc app on apache they may not be the same path.
This error occurs because there is a bug in mono System.Web
It contain this check (https://github.com/mono/mono/blob/mono-3.2.1-branch/mcs/class/System.Web/System.Web/HttpRequest.cs#L1565)
if (!isAppVirtualPath && !virtualPath.StartsWith (appVirtualPath, RuntimeHelpers.StringComparison))
throw new InvalidOperationException (String.Format ("Failed to map path '{0}'", virtualPath));
To fix this, you can comment those lines in Mono surce code and re-compile Mono.
This bug is in latest Mono also.

I had the same error, with exactly the same stacktrace.
It only occured on the first request when apache was just started. The error did not occur after the first request.
I solved this by removing WebMatrix.WebData.dll
This will probably have some consequences when you use SimpleMembershipProvider and it might affect OpenAuth functionality on MVC4.
I have an Apache server with mod_mono hooked up to a legacy ASP.NET application. I can't seem to get this application to work if I move it from a top level folder.
For example, the following mono .webapp successfully works at http://localhost/Service.asmx (as my web app is in folder2):
<apps>
<web-application>
<name>Test</name>
<vpath>/</vpath>
<path>/srv/aspnettest/folder1/folder2</path>
<vhost>localhost</vhost>
</web-application>
</apps>
However, due to a legacy URL, I need my web application to exist two subfolders deeper like so:
<apps>
<web-application>
<name>Test</name>
<vpath>/</vpath>
<path>/srv/aspnettest/</path>
<vhost>localhost</vhost>
</web-application>
</apps>
If I try to go to http://localhost/folder1/folder2/Service.asmx it fails with
HTTP 500. Error processing request.

How can I successfully get a web app in subfolders? Thanks.
Turns out this was an Apache configuration issue that was unrelated but caused this as a side effect. I had my VirtualHost setup incorrectly.
