Could not load file or assembly 'DocumentFormat.OpenXml

Question

I\'m keep getting this error is VS2013

Could not load file or assembly \'DocumentFormat.OpenXml, Version=2.0.5022.0, Culture=neutral, PublicKeyToken=31b

Answer 1

At the time of writing this answer, there are 3 versions of Open XML SDK:

• Open XML SDK 1.0 (NuGet link)
• Open XML SDK 2.0 (NuGet link)
• Open XML SDK 2.5 (NuGet link)

You most probably have referenced in your project DLL version 2.5 which was installed on your machine.
To get required v2.0 assembly, I suggest you to use NuGet I provided above.
