[zeromq-dev] ASP.NET Issue

[lanre lawal]

Hi Guys,

    So i've successfully completed a project with the clr-zmq binding for C# on ASP.NET. Now everything works fine when I test my project from Visual Studio 2010 (ctrl + F5). Now I want to distribute the project to other windows users, but when I drop the project folder into the C:/inetput/wwwroot folder and I test it, I get this error that I can't seem to understand. It reads as follows:

Server Error in '/' Application.

---

Could not load file or assembly 'clrzmq' or one of its dependencies. An attempt was made to load a program with an incorrect format.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: System.BadImageFormatException: Could not load file or assembly 'clrzmq' or one of its dependencies. An attempt was made to load a program with an incorrect format.

Source Error: 

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

Assembly Load Trace: The following information can be helpful to determine why the assembly 'clrzmq' could not be loaded.

WRN: Assembly binding logging is turned OFF. To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1. Note: There is some performance penalty associated with assembly bind failure logging. To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

I read somewhere that it has to do with a machine type issue (32bits VS 64bits). But I was wondering why it would work when i'm testing through visual studio and not work when testing through the normal localhost testing. Mind you both testing methods are done on 1single machine which is my machine. Please does someone have an idea of why this might be happening.

Seems that there's an architecture mismatch involved (32 bits vs. 64 bits?)

Yes I understand that. But the thing is on the clr-zmq binding page, there's really not much detailed documentation about how to select for the correct platform. This is something I find very disturbing about ZMQ. Its not properly documented at all. They don't even tell you what folder to look in to find the correct dll files for 32bits or 64bits. You guys need to understand that not everybody has gone through these kind of processes before so its only fair if you give proper step-by-step processes. I'll be glad if someone does that here. I just went into one of the folders and copied out a dll without knowing what architecture it was for.

Hello,

The process of choosing the target platform is no different from any
other Visual Studio project. I am not sure whether our documentation
efforts are best spent creating documentation for platform specific
tools, especially when this information is fairly easy to find online:

http://stackoverflow.com/questions/3661368/how-can-i-choose-between-32-bit-or-64-bit-build-in-c-sharp-express
http://msdn.microsoft.com/en-us/library/ms185328(v=vs.80).aspx

For the locations of the DLLs and import libraries you should again
refer to your IDEs documentation, as you can easily check this from
project configuration.

Thanks,
Mikko
