Could not load type 'Microsoft.Xrm.Sdk.Deployment.DeploymentServiceFault' from assembly 'Microsoft.Xrm.Sdk

Posted on by Xavier Villafuerte 352

Good day to everyone. I would appreciate your advise about how to troublsehoot this issue:

Scenario:

  • SSIS project with target to SQL 2016 and created using VS 2017
  • C# Script component that needs to connect to Dynamics 365 v9 Online. Code target to .net 4.6.2. SDK references to the lastest dll versions available in nuget.
  • Script compiled with no errors.
  • Connection String tested in XRM Toolbox with no problems.

Problem:

The line of code in the Script:

  •  CrmServiceClient crmConn = new CrmServiceClient(connectionStringCRM);

Produces the following exception:

  • Could not load type 'Microsoft.Xrm.Sdk.Deployment.DeploymentServiceFault' from assembly 'Microsoft.Xrm.Sdk, Version=9.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.

I tried the same approach and code several times in other projects with no problems so this time I am totally lost.

Thanks for any advice.

    Hi Xavier,

    The exception seems to be about Microsoft.Xrm.Sdk.Deployment, this package contains Microsoft.Xrm.Sdk.Deloyment.dll, can you try adding this NuGet package?

    www.nuget.org/.../Microsoft.CrmSdk.Deployment

    If you've got it working in XrmToolBox, you can open the folder where XrmToolBox is and check if that DLL is inside.

    Regards,
    Abby

    Thanks Abby. Microsoft.Xrm.Sdk.Deloyment.dll was already referenced in the project and it was obtained from nuget. The latest version of the dll was 9.0.2.12. Problem is still there.

    After a little bit of troubleshooting I found the cause for the problem. Because I was working on a SSIS package, I was using the approach documented in this link "blogs.msdn.microsoft.com/.../" to use the SDK dlls from a local path. It seems that the order of the dlls being called in the methods described in the article it is important because when the Xrm.Tooling.Connector.dll  reference was included prior to the Xrm.Sdk.dll, the connection worked like a charm even thought there was no any reference to the Microsoft.Xrm.Sdk.Deloyment.dll in the project. I hope this helps somebody in the future.
