Invalid version of Newtonsoft.json with Dropbox.API v4.0.30319

Invalid version of Newtonsoft.json with Dropbox.API v4.0.30319

Hi,

 

I'm getting the following run-time error when trying to upload a file to Dropbox using the DropBox.API for .NET.

 

Could not load file or assembly 'Newtonsoft.Json, Version=7.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

 

The Dropbox version I'm using is v4.0.30319 and it comes installed with NewtonSoft.Json version v7.0.1 but I've upgraded my version to v10.0.3. I've checked the Dropbox.API dependencies and it is stating that it should use NewtonSoft.Json v7.0.1 or higher which it is.

 

The weird thing is that I upgraded weeks ago to 10.0.2 and never had any problems, certainly not related to not finding v7.0.1.

 

Any ideas how I can resolve this?

 

Thanks.

I managed to fix it, well thanks to StackOverflow.

 

I added the following to my app.config file in the Configuration section.

 

<runtime>

  <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">

    <dependentAssembly>

      <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />

      <bindingRedirect oldVersion="0.0.0.0-7.0.0.0" newVersion="10.0.0.0" />

    </dependentAssembly>

  </assemblyBinding>

 </runtime>

 

 

Hopefully, it will be of some help to others!

@MathanKumar Unfortunately, it's not clear what the issue may be, and it's likely related to the particular project configuration. If you're still seeing this, please share a sample project that reproduces the issue so we can reproduce it and investigate. Thanks!
