Get Spreadsheetlight working

Spreadsheetlight is a dotnet library for creating Excel documents with all it’s wonderful features. The Spreadsheetlight nuget has no dependencies on nuget packages, but does have a dependency on Open XML SDK 2.0. This can be installed with the DocumentFormat.OpenXml 1.0.0 nuget.

But after a while everything stopped working, because you tried updating the DocumentFormat.OpenXml to the latest version 2.5.0.

An unhandled exception of type ‘System.TypeLoadException’ occurred.
Additional information: Could not load type ‘DocumentFormat.OpenXml.Spreadsheet.SmartTags’ from assembly ‘DocumentFormat.OpenXml, Version=2.5.5631.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35’.

An unhandled exception of type ‘System.IO.FileLoadException’ occurred.
Additional information: Could not load file or assembly ‘DocumentFormat.OpenXml, Version=2.5.5631.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35’ or one of its dependencies. The located assembly’s manifest definition does not match the assembly reference.

Solution

Revert back to DocumentFormat.OpenXml version 1.0.0

Install-Package DocumentFormat.OpenXml -Version 1.0.0

Remove the assemblyBinding from the app.config

<configuration>
  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <!-- Remove dependentAssembly for DocumentFormant.OpenXml -->
      <dependentAssembly>
        <assemblyIdentity name="DocumentFormat.OpenXml" publicKeyToken="31bf3856ad364e35" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-2.5.5631.0" newVersion="2.5.5631.0" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>
</configuration>

Thank you so much this worked like a charm. I figured out that I needed to revert the version of the OpenXML and I did that but I was really banging my head against the wall trying to figure out that second manifest error message. Thanks again.
