Workflow error "Could not load file or assembly 'Microsoft.XRM.SDK'

(0) ShareShare
ReportReport
Posted on by Community Member

I have created a workflow using Visual Studio 2015 with Dynamics SDK.

I have successfully published this workflow to Dynamics 365 CRM (online) using the Plugin Registration Tool which was present in the SDK.

When I trigger the process to run I get the error message "Could not load file or assembly 'Microsoft.Xrm.Sdk, Version=9.0.0.0, Culture=nuetral, PublicKeyToken=1234' or one of its dependencies.  The system cannot find the file specified.

The version of XRM.SDK that I am using in my Visual Studio project is 9.0.0.0.

The version of my Dynamics 365 instance is: Version 1612 (8.2.2.330)

This is my first time creating a workflow, so am a bit lost in terms of potential fixes.

    Thanks for the answers all.

    I reduced the version of the SDK and it worked.

    Can you use the XRM.SDK dll in console application and connect CRM and execute some logic. If its not work then try with some lower version as Wei suggested.

    Hope this helps.

    Hi,

    It certainly does look like a dll version issue. You should use the dll as per your current CRM versions.

    Hope this helps.

    Hi,

    It seems that the version is mismatch, Maybe you can try to use the lower version of SDK. You can refer to below pictures. I am using V8.2 version of SDKto connect Dynamics 365 instance is: Version 1612 (8.2.1.176)
