2. An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)

Stack Trace :

This means that you are trying to use x86 dll in x64 proj or vice versa.
If you need x64 dll, then you can get it here Later, I build an assembly for Windows.

[patachi]

hmm
I tried both x86 & x64 mode still Unable to load DLL
and the same error :
An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B))

[hey-red]

@patachi I'm updated the package with windows support (included x64 dll). Now you do not need to install the DLL manually.

[patachi]

ohh thank you ^_^

welp i create new classic win form project and added Mime with NuGet (Update Saturday, April 8, 2017 (4/8/2017)) and write a simple code like

    public string TryToGetFileExtension(byte[] fileBuff)
    {
        var fileExtension = "";
        try
        {
            //HeyRed.Mime.MimeGuesser.MagicFilePath = @"magic.mgc";

            var tmpLength = (fileBuff.Length > 512 ? 512 : fileBuff.Length);
            var tmpBuff = new byte[tmpLength];
            Array.Copy(fileBuff, tmpBuff, tmpLength);
            fileExtension = HeyRed.Mime.MimeGuesser.GuessExtension(tmpBuff, tmpBuff.Length);

            tmpBuff = null;
        }
        catch (Exception exp)
        {
            System.Diagnostics.Debug.WriteLine(exp.Message);
        }

        return fileExtension;
    }

and still i got this error :
Unable to load DLL 'libmagic-1': The specified module could not be found. (Exception from HRESULT: 0x8007007E)

[hey-red]

Hmm, it's very strange. Which windows version you are using? 32 or 64 bit?
Off course I should've be test it with full .net framework.

[patachi]

win 10 x64

[hey-red]

Ok, I have same system.
It seems that problem is that DLL is not copied to output directory.

[hey-red]

@patachi It's seems like i'm solve that problem. Update package and you will need to set platform x64 in your application.

[patachi]

yup it works fine
thanks @hey-red

@hey-red Last version (2.3.0) not working for AnyCPU platform.
Current configuration:
Win 10, x64
VS 2017, Platform: AnyCPU

[hey-red]

@sacerdotu change platform to x64.

[sacerdotu]

@hey-red But I need anycpu :) If I change to x64 it will work for sure.

[sacerdotu]

@hey-red This is an issue that should be fixed

at HeyRed.Mime.MagicNative.magic_open(MagicOpenFlags flags)
at HeyRed.Mime.Magic..ctor(MagicOpenFlags flags, String dbPath)

at MimeHelper.Program.Main(String[] args) in C:\Users\sacerdotu\documents\visual studio 2017\Projects\MimeHelper\MimeHelper\Program.cs:line 28

[hey-red]

Currently there is no x86 support. Maybe later i'm trying to build 32-bit libmagic, and АnyCPU will be works by default.

[sacerdotu]

Perfect. Waiting for the new version!

@hey-red Any news?

[himadrinath]

@hey-red uploaded to azure change the application setting to 64bit but problem not solved.
getting this

check the server

but locally its working fine.. what is happening can u help me?

[hey-red]

@himadrinath
I did not work with azure, but if your app is self contained(contains all dependencies in working dir), then you need to copy libmagic and and other files from win runtime into directory that contains your app.

[himadrinath]

@hey-red i did now i am getting another error

An unhandled exception occurred while processing the request.

BadImageFormatException: An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)

[hey-red]

Your VM under linux or windows?

[himadrinath]

@hey-red windows

[himadrinath]

@hey-red i found this aspnet/KestrelHttpServer#1625 (comment)

[hey-red]

Yep, its seems like app run in x86 mode. Also, by default azure VM uses x64 windows?
Change target platform to x64 and publish your app again.

[himadrinath]

@hey-red working on it. lets see what happen. i will inform you the result

[himadrinath]

@hey-red i changed the runtime to win-x64 and deploy to azure now its working fine. thanks for your help
