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

I need to launch an .exe executable, so I installed monodevelop:

I have another setup in Ubuntu 14.04 LTS and that one works, so it might be something with the mono version, or maybe I'm missing some library?
Turns out simply creating the folder using mkdir
sudo mkdir /etc/mono/registry
and setting the right permissions using chmod
sudo chmod uog+rw /etc/mono/registry
does the trick.
However I still don't understand where such a folder is hidden in Ubuntu and why it doesn't need to be created there, as well as why it isn't created automatically during the installation.
You can set MONO_REGISTRY_PATH to point to a directory that you control:
bash
mkdir my-registry
MONO_REGISTRY_PATH=`pwd`/my-registry

You should try to use latest Mono and latest MonoDevelop,

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).
