Hello,

After upgrade to CRM 365 version 8.2.9, I found the following error message in Event Viewer of CRM 365 server:

Monitoring runtime failed: Machine: TEST-CRM365-01: Exception: SmokeTests failed with exception : System.TypeInitializationException: The type initializer for 'Microsoft.Crm.Monitoring.MonitoringSettings' threw an exception. ---> System.IO.FileNotFoundException: Could not load file or assembly 'Newtonsoft.Json, Version=6.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed' or one of its dependencies. The system cannot find the file specified.

However, in our plugin solution, we're reference Newtonsoft.Json.dll version 8.0.0.19514. Why it complains about version 6.0.0.0? 

It doesn't fix my problem by trying the following:

1. add Newtonsoft.Json.dll under C:\Program Files\Microsoft Dynamics CRM\Monitoring\bin

2. add Newtonsoft.Json.dll to web.config under assemblyBinding\dependentassembly

Can anyone help this?

Thanks.

    Did you find a resolution for this issue? We are having the same recurring error with Dynamics 365 8.2.7.

    Hi,

    I think you using newtonsoft.json.dll in some plugins or custom activity, so try to add this dll to the below path:

    C:\Program Files\Microsoft Dynamics CRM\server\bin and C:\Program Files\Microsoft Dynamics CRM\crmweb\bin

    then try again and let me know what happened.

    Hi howexg9,

    You can merge Newtonsoft.Json into your Plugin assembly by using ILMerge but this is not supported.

    I recommend using the System.Runtime.Serialization Namespace for serializing and deserializing objects, the System.Xml.Serialization Namespace to serialize objects into XML format documents or streams, and the System.Text.Json Namespace to serialize objects into JSON format documents or streams.

    I also encountered this issue. 

    Please apply this Workaround to solve this issue:

    1. Copy the file Newtonsoft.Json.dll  from the Directory C:\Program Files\Microsoft Dynamics CRM\Server\bin to the Directory C:\Program Files\Microsoft Dynamics CRM\Monitoring\bin

    2. Restart MSCRMMonitoring Service

    3. Perform SmokeTests.exe to verify Monitoring Report. You should this output
