DocumentFormat.OpenXml in Ubuntu server

Question

I have a basic C# application where Open XML SDK is used. I want to make it run in my Nginx & Ubuntu & DigitalOcean server.

The application compiles and works well in Windows, and my Mac with mono. Then, I installed mono in the Ubuntu server, and scp the .exe file to the server, and run mono ConsoleApplication2.exe, it returned the following error:

Unhandled Exception:
System.IO.FileNotFoundException: Could not load file or assembly 'DocumentFormat.OpenXml, Version=2.5.5631.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies.
File name: 'DocumentFormat.OpenXml, Version=2.5.5631.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'

I have found this link, it seems that the problem comes from the version of DocumentFormat.OpenXml. But how could I install its right version in a Ubuntu server?

Could anyone help?

Update 1: Then, I tried to install Open XML SDK 2.6.1, but there is no makefile. Otherwise, for Open XML SDK 2.5, I don't know where to find a release distribution.

Update 2: I should have tried build.open-xml-sdk.sh... I tried to run it in the server, but it gives an error. Does anyone know what's wrong here?

Update 3: I uninstalled mono, and followed this link:

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF
echo "deb http://download.mono-project.com/repo/debian wheezy main" | sudo tee /etc/apt/sources.list.d/mono-xamarin.list
echo "deb http://download.mono-project.com/repo/debian wheezy-apache24-compat main" | sudo tee -a /etc/apt/sources.list.d/mono-xamarin.list
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install mono-complete

mono was re-installed successfully. Then I tried build.open-xml-sdk.sh again, but it returned the same error.

Update 4: Following the comment of ZagNut, I tried to add DLLs to GAC. I noticed two things:

1) I downloaded the source code and generated DocumentFormat.OpenXml.dll and System.IO.Packaging.dll, they made my program compile well in Visual Studio. However, when i tried to add them to GAC by gacutil, it tells me they need a strong name.

2) Then I tried to add strong name to them by following this page, I realised that the new 2 dlls could not work correctly in Visual Studio anymore:

Answer 1

just put the binaries you need alongside your application executable.

for the binaries, you can build it yourself: https://github.com/OfficeDev/Open-XML-SDK

or download from below and just extract the binaries using Universal Extractor or installing it and finding them.
