Azure Copy from TFS2017 to Azure VM Error: Could not load file or assembly 'Newtonsoft.Json, Version=9.0.0.0

Question

I am a newbie playing with TFS so you may need to ExplainLikeIamFive what is going on with this.

I have been asked to upload a Blob file to Azure VM from using our onsite TFS build pipelines.

We are using TFS 2017 and the Azure File Copy task (version 1.0) in TFS.

I am getting the following error:

> 2020-07-31T09:07:45.4248226Z ##[command]Import-Module -Name C:\Program Files\WindowsPowerShell\Modules\AzureRM\5.7.0\AzureRM.psd1 -Global

> 2020-07-31T09:07:45.9092180Z ##[section]Finishing:  Azure Blob File Copy

I have the following in my machine.config file located in Microsoft.Net\Framework64\v4.0.30319

<runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral"/>
        <bindingRedirect oldVersion="0.0.0.0-9.0.0.0" newVersion="9.0.0.0" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>

It might be caused by the older version of azure powershell on your local agent machine. It is said the latest version of azure powershell fixed the error Could not load file or assembly 'Newtonsoft.Json...' Checkout a similar issue here for more information.

You can have a try upgrading the azure powershell on your local agent machine to the latest version.
