System.DllNotFoundException: libpcsclite.so.1 assembly:<unknown assembly> type:<unknown type> member:(null)

Researched this issue many times but didn't found solution of it. Working with xamarin forms version 5.0.0.2012, on win 10 os (saw many solutions for mac or linux but didn't found any for windows), using PCSC library version 5.0.0. Trying to invoke context.Establish method while debugging on Android 8.0:
public SimpleReader(ISCardContext context, bool releaseContextOnDispose = false)
{
if (context == null)
{
context = (ISCardContext) new SCardContext();
context.Establish(SCardScope.System);
releaseContextOnDispose = true;
}
this._context = context;
this._reader = (ISCardReader) new SCardReader(context);
this._releaseContextOnDispose = releaseContextOnDispose;
this._disconnectReaderOnDispose = true;
}
When, exception occur with message below:

Does anyone faced with this issue?

The PCSC library does not appear to explicitly support Android. In my experience, nugets that work with Xamarin.Android have explicit dependencies set for the platform, but this one does not.
The library tries to use P/Invoke wrappers around native code. You can see that there are implementations for a number of operating systems here, but I don't see any references to Android. The stack trace shows that the code is deciding to use the Linux wrapper, which makes sense. It's looking for the libpcsclite.so.1 native "C/C++" library, but it's not finding it. That library has a home page that does not reference Android.
The PCSC nuget docs state:
pcsc-sharp does not contain any device drivers. A PC/SC compliant
reader + driver is mandatory.
That's the libpcsclite.so.1 . Either your Android device doesn't provide it, or if it does, it's not in a location that your Android app can find it. My Android device (running Android 9) does not have that library in any of /system/*lib* directories, which means that at least for my device someone would need to compile that native library for the CPU (usually arm64) for the device. If you can either compile the native code yourself or find someone who has, AND the native code supports the reader on your Android device, then you could get the whole thing to work.
I don't have any experience with PCSC myself - just some experience with Xamarin and native libraries.

PrecompiledAssemblyException: Multiple precompiled assemblies with the same name UnityEditor

When I imported an asset to unity then I try to run the game this message appeared :

Glade can't find gui.glade

I'm using in my code:
Glade.XML gxml = new Glade.XML (null, "gui.glade", "PublicanCreators", null);
The gui.glade file is placed in the same directory as the Program.cs (which runs the code).
The compiling process has suceeded. But while running the exe i'm getting:
Stacktrace:
at <0xffffffff> at (wrapper managed-to-native)
Glade.XML.gtksharp_glade_xml_get_filename (intptr) at Glade.XML.get_Filename () at

What can i do?

Looks like you need gui.glade in the bin folder, not the source folder. Make sure it is included in your project file and is copied on compile.

It looks like the solution is to change the code to:
Glade.XML gxml = new Glade.XML ("gui.glade", "PublicanCreators", null);
There it finds the file.

Calling Mono exe from C does not find libc

In Ubuntu, I am calling a C# executable from C using Mono (v3.2.8) and the embedded Mono runtime. When I call the exe (.NET 4.5) from the command line (ie, mono testFile.exe), it works fine. However, when I run my C test program, it throws a C# exception:
libc at at (wrapper managed-to-native) System.Platform:uname (intptr)

at MyClass.MainClass.Main (System.String[] args) [0x00000] in <filename unknown>:0
I've narrowed it down to this one line of code:
WebRequest request = WebRequest.Create("http://www.google.com");
Looking through the call stack and the mono source code, I believe the failure is associated with the calling of the native 'uname' function in libc.so (the CheckOS() function, line 50 of mcs/class/System/System/Platform.cs):
if (uname (buf) == 0) {
I think what is happening is that the p/Invoke layer cannot locate libc.so. However, when I make the same call in my executable's Main() function, it executes fine, I am confused why it works in one place but not the other. It is also strange that the exception message is not a DllNotFoundException, but rather this generic "libc" message (though I have confirmed that I get the same message when I try to p/Invoke with a bogus .so).
My C code:
int main(int argc,const char* argv[]) {
MonoDomain* domain=mono_jit_init("testFile.exe");
MonoAssembly* assembly=mono_domain_assembly_open(domain,"testFile.exe");
MonoImage* image=mono_assembly_get_image(assembly);
const char* args[1];
args[0]="testFile.exe";
mono_jit_exec(domain,assembly,1,(char**) args);
}
My C# code:
namespace MyClass {
class MainClass {
public static void Main (string[] args) {
WebRequest request=WebRequest.Create("http://www.google.com");
}
}
}
gcc compile options are:
gcc cTest.c -I/usr/include/mono-2.0 -DREENTRANT -lmono-2.0 -lm -lrt -ldl -lpthread
mono compile options are:
dmcs -out:testFile.exe -platform:anycpu -sdk:4.5 -target:exe -unsafe+ -main:MyClass.MainClass -reference:System,System.Configuration,System.Data,System.ServiceModel,System.Web,System.Xml *.cs
Update:
I used MONO_LOG_LEVEL and MONO_LOG_MASK to trace the .so search sequence and found that the sequence on the successful call was entirely different from the unsuccessful one. So it is searching, just not very well. I then copied my libc.so.6 to the current directory, renamed to libc.so, and then set LD_LIBRARY_PATH to the same location. This gave me success. I am now having my Linux guru look into what can be done to make this solution more 'correct', but at least I have a running program. This may be the same problem as mine (though the solution's not working for me).

The problem is you are missing the dll mapping (mono_config_parse). The following will work with mono 3.x and 4.x embedding and avoid your libc error.
#include <mono/jit/jit.h>
#include <mono/metadata/environment.h>
#include <stdlib.h>
int
main(int argc, char* argv[]) {
MonoDomain *domain;
const char *file;
int retval;
mono_config_parse (NULL);
domain = mono_jit_init ("textFile.exe");
MonoAssembly *assembly;
assembly = mono_domain_assembly_open (domain, "testFile.exe");
mono_jit_exec (domain, assembly, argc, argv);
retval = mono_environment_exitcode_get ();
mono_jit_cleanup (domain);
return retval;
}
Certain features of the runtime like Dll remapping depend on a configuration file, to load the configuration file, just add:
mono_config_parse (NULL);
Which will load the Mono configuration file (typically /etc/mono/config).
http://www.mono-project.com/docs/advanced/embedding
FYI: On Ubuntu 15.04, I am using:
gcc main.c `pkg-config --cflags --libs mono-2`
You can update that of course to grab the mono-sgen vs. the boehm jit.
On OS-X:
gcc main.c -m32 -framework Foundation -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk \
-lmonosgen-2.0 \
-I/Library/Frameworks/Mono.framework/Headers/mono-2.0 \
-L/Library/Frameworks/Mono.framework/Libraries

I've run into this issue as well. What I noticed is that the mkbundle output lists the assemblies which it embeds, and that the System.Net.dll was not included. After adding it manually on the mkbundle command line, it all worked fine.
The command line I'm using now:
mkbundle my.exe --deps --keeptemp --static --config /etc/mono/configlibc --machine-config /etc/mono/4.5/machine.config System.Net.dll -o bssetup.exe
The configlibc file is a modified copy of the default config file in that directory. The modifications were to remove all mapping lines, except the one for libc.
Hope it helps anyone!

Based on your update, it looks like the application is searching for libc.so instead of libc.so.6. You got it working by manually pointing your LD_LIBRARY_PATH to the current folder having the libc.so that you copied.
Suggestion: ask your Linux guru to symlink libc.so to libc.so.6 in your normal search paths for your application to work.

Mono gets native exception when trying to access MVC site

I could use a hand in figuring out what's wrong in my mono + mod-mono + MVC setup:
I'm trying to get my Asp.Net MVC3 site deployed on an Apache server running on CentOS 6.5. I think I have a working mono 3.10.1 installation, as I can run C# console programs by issuing mono myprogram.exe on the Linux platform. Also, I have mod_mono (3.8) configured and I can access simple web applications. I've tested with a simple aspx page that prints out the current date, just to see that my Apache and mod_mono are actually communicating correctly.
But the problem arises when I try to deploy a MVC3 site. When trying to access it on a browser, I get 500 error and the httpd/error_log says:

So, according to the warning I created a file /root/.gdbinit and added line:
add-auto-load-safe-path /usr/bin/mono-sgen-gdb.py
No effect. I verified that mono-gdb.py and mono-sgen-gdb.py files exist, also tried adding the folder only: add-auto-load-safe-path /usr/bin/ - no effect again. Tried running gdb and issuing the command 'add-auto-load-safe-path /usr/bin/mono-sgen-gdb.py' on gdb - no effect. So there must be something I'm doing wrong, or something wrong in my setup.
Any idea what this could be all about and where should I continue in searching for solution?
