Unhandled Exception of type 'System.TypeInitializationException' occured in ZeroMQ.dll about clrzmq4

[tuldok89]

Even a minimal test case like the one below is throwing the same error.

using System;
using ZeroMQ;

namespace TestCase
{
    class Program
    {
        static void Main(string[] args)
        {
            using (var context = new ZContext())
            {

            }
        }
    }
}

Please set the files in i386 and amd64 to "copy if newer" (.dll for Windows and .so for Linux).

[tuldok89]

Thanks, it solved the issue.

I didn't expect that :) I guess I'm used to some NuGet packages that automatically copies the native DLLs to the build folder.

[metadings]

Yeah, sadly isn't that for native dlls... I'll have to make them embedded resources, however that will give some weight to the binary...

[metadings]

The examples are cool right? I like Espresso...:

Yeah, the examples are nice 👍 I've just started learning ZeroMQ, and I prefer this lib, over the pure CLR one, since it's much closer to the C API.

Anyway... IIRC the approach used by the SQL Server compact NuGet package is that, it executes a powershell script to automatically copy the native binaries to the build folder. They're not embedded resources, I think.

[metadings]

Thanks 👍

I'll have to look into the SQL Server compact package!

Thanks, this issue is solved by the above answer: "Please set the files in i386 and amd64 to "copy if newer" (.dll for Windows and .so for Linux)."

🍏 💚 🆒 ♻️ 👍

[jugalpanchal]

This is a very silly problem. The answer is perfect. It solved my problem.
Thank you so much! 👍

I have the same problem..... What do you mean with "Please set the files in i386 and amd64 to "copy if newer" (.dll for Windows and .so for Linux)."? I do not know how to proceed.

Thanks,

[metadings]

I'm sorry, I don't know how to say this otherwise, you should try harder.

"Please copy the folders i386 and amd64 into the project's output directory."

You should end up using a directory structure like this one:

\MyProject
	\bin
		\Debug
			\amd64
				\libzmq.dll
				\libzmq.so
			\i386
				\libzmq.dll
				\libzmq.so
			\MyProject.exe
			\ZeroMQ.dll
	\amd64
		\libzmq.dll
		\libzmq.so
	\i386
		\libzmq.dll
		\libzmq.so
	\AssemblyInfo.cs
	\Program.cs

So, I know that this is an old question, but what could be the cause and possibly fix when the inner exception is not "UnmanagedLibrary" but a NullReferenceException?
I'm trying to create a ZContext in the OnStart() method of a windows service and get the TypeInitializationException when trying to call new ZContext().

I aldready copy the amd64 and i386 folders to the output folder and I have ZeroMQ installed using NuGet.
If I create the context in a test and pass it to the class that needs to use it, it works without any complications.

Again sorry for reopening the issue, but I really am at my wits end.
