Hosting a WCF service in Mono console application on Mac Os X - wcf

When I try to host a WCF service, that works perfectly in Windows, in a mono console application I get the following error (*):
An element with the same key already exists in the dictionary.
I don't get at all why this is happening or where I need to look to fix this. Anyone who has experienced this or can point me in the right direction?
I am using Mono 2.10.8 on a Mac running Os X 10.6.8.

I have an application that is made by .NET and i use mono 6.4.0.198 (i use the newest mono so the app is compatible with Catalina MacOS) to run it on the Mac machine, on my machine the mono is installed so the app works fine, but when i run the app on other Macs it return the following exception

clearly its a missing dll libmono-native-compat.dylib i added this dll at the application resources alongside other dlls but the app still returning the same missing dll exception, how i can direct mono to dll so i would fix this problem
I had many errors when I installed the macOS Catalina until I decide to give permission to my /private/tmp folder. It seems all apps work now. I don't know if it's your case but just in case try this:
sudo chmod 777 /private/tmp
I solved this issue by
creating a file called fix.config and it contains the following XML
<configuration>
<dllmap dll="System.Native" target="libmono-native-compat.dylib" os="!windows" />
<dllmap dll="System.Net.Security.Native" target="libmono-native-compat.dylib" os="!windows" />
<dllmap dll="System.Security.Cryptography.Native.Apple" target="libmono-native-compat.dylib" os="osx" />
</configuration>
the i copied the three dylibs that are mentioned in the XML to the path Application/MyApp.app/Contents/lib
then in the in the building script i added to the tool mkbundle the following command
--config $SETUP_DIR/fix.config and setup path is the path where im creating my .pkg file
NOTE: im using mono version 6.4.0.198

Creating Roslyn MetadataFileReference bombs on mono/Linux

I'm doing on some basic Roslyn stuff, and have run into what appears to be a mono compatibility issue. Wanted to make sure I'm not doing something wrong and hear other people's experience. Am using Roslyn from the Microsoft.CodeAnalysis nuget, version 0.7.4091001-beta (latest).
var mscorlib = new MetadataFileReference(typeof(object).Assembly.Location);
var compilation = CSharpCompilation.Create("Temp", new SyntaxTree[0], new[] { mscorlib });
compilation.GetAssemblyOrModuleSymbol(mscorlib);
While this works on Microsoft .NET, on mono on Linux the last line produces the following exception:
[ERROR] FATAL UNHANDLED EXCEPTION: System.ArgumentException: Absolute path expected.
Parameter name: fullPath

at playground2.MainClass.Main (System.String[] args) [0x00000] in <filename unknown>:0
There's obviously some sort of path parsing Linux/Windows sadness going on here. My current workaround is to create the reference to corlib thus:
var mscorlibMetadata = AssemblyMetadata.CreateFromImageStream(new FileStream(typeof(object).Assembly.Location, FileMode.Open, FileAccess.Read));
var mscorlib = new MetadataImageReference (mscorlibMetadata);
Does anybody know anything about this?
This is a bug in Roslyn.
You can send them a pull request to fix PathUtilities.GetPathKind to be aware of Linux-style paths by checking Path.DirectorySeparatorChar.

Embedded mono + app.config

I have embedded mono in a c++ program and loaded a dll which requires an app.config. I am getting this kind of error, does someone have an idea on how to ship *.config with an embedded mono ?

Self answer : you can't (as of 2013-04-30). To enable this behaviour, I had to change mono's framework sources mono/mcs/class/corlib/system/appdomain.cs :
public AppDomainSetup SetupInformation {
get {
return SetupInformationNoCopy; // newline
// AppDomainSetup setup = getSetup (); //old
// return new AppDomainSetup (setup); //old
}
}

RavenDB client onlinux connecting to windows server using mono http

I've just tried connecting to my RavenDB windows instance from linux using mono. I'm getting a bizarre error with it, that seems to be mono related rather than raven related.
Here is my recreate code (works on windows):
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Raven.Client.Document;
namespace ConsoleApplication2
{
class Program
{
static void Main(string[] args)
{
try
{
var store = new DocumentStore()
{
ConnectionStringName = "RavenDB",
EnlistInDistributedTransactions = false
};
store.Initialize();
using (var session = store.OpenSession("system-events"))
{
session.Store(new { Name = "Test" });
session.SaveChanges();
}
Console.WriteLine("done");
}
catch (Exception ex)
{
Console.WriteLine(ex.ToString());
}
Console.ReadKey();
}
}
}
and my mono version:

I think I found it. DeflateStream has extern references to zlib. If you look at the zlib header file, you will find some comments:
deflate() returns Z_OK if some progress has been made (more input
processed or more output produced), Z_STREAM_END if all input has been
consumed and all output has been produced (only when flush is set to
Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for
example if next_in or next_out was Z_NULL), Z_BUF_ERROR if no progress
is possible (for example avail_in or avail_out was zero). Note that
Z_BUF_ERROR is not fatal, and deflate() can be called again with more
input and more output space to continue compressing.
The message Internal error (no progress possible) is what DeflateStream returns when getting a Z_BUF_ERROR - but it doesn't continue, it treats it as a hard stop. It should treat it as a warning and continue. At least, that's my interpretation.
Can you raise this with the mono support team? I'm not active in that group. Thanks.

NHibernate ISession.Query<T> in Mono/NUnit throwing exception

I'm attempting to get my first NHibernate project up and running in Mono/openSUSE 11.4. My unit tests are working successfully under Windows but when I attempt to run the same tests on Mono I'm getting an exception when I try to get back the Query object from my NHibernate session.
Saving data through NHibernate seems to be working correctly.
I'm using Mono 2.10.2 and NUnit version 2.4.8 with Fluent NHibernate 1.2 for NHibernate 3.1.
I've included the full output from nunit-console just in case:

Following AlexCuse's advice I ran monodis against the DLLs. All of the NHibernate dlls are set to CopyLocal. They seem to be happy with monodis. NHibernate.dll doesn't however. Here is the end of the output:

I gave up and installed Fluent NHibernate 1.1 with NHibernate.Linq-2.1.2-GA. All seems to be happy in the world of my unit tests but I'm still trying to figure out what is going so wrong with the current version.
I rolled back to use NHibernate 2.1.2 with the additional Linq library which worked fine but then I revisited this the other day I found the fix was ridiculously simple.
The mono-wcf package was not installed on my system. NHibernate 3.2 requires WCF. Now I've installed it, it is all working perfectly!
Are all of your libraries referenced with "CopyLocal" set to true? If so, running
/path/to/mono/monodis <DLLNAME>
on your bin directory may help to determine if they are valid assemblies: (http://comments.gmane.org/gmane.comp.gnome.mono.aspnet/1106)
I've seen this (on older versions of mono AND fluent NHibernate) when dealing with classes that were not CLS-compliant, but in that case it was able to load the assembly to use other classes (I was not loading with reflection though).
