Dynamics CRM 2016 Online Security/Isolation Mode

I have a simple post create plugin on the Account entity that makes a subsite in SharePoint online with the same name of the Account that has been created.

I have used the SharePointOnlineCredentials class from the Microsoft.SharePoint.Client.Runtime assembly to login to the SharePoint instance.

The plugin works on an on-premise instance as long as the plugin is set to isolation mode = none.

When I run the plugin in Sandbox isolation mode I get the error below (online version error).

I want to run this plugin on an online instance of SharePoint, but as, I believe, I cannot run online with an isolation mode = none, is there another way of running code using this SharePoint assembly on an online CRM instance?

Message: Create, Method: ExecutePluginLogic Exception: System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.    at System.Security.CodeAccessSecurityEngine.Check(Object demand, StackCrawlMark& stackMark, Boolean isPermSet)    at System.Security.CodeAccessPermission.Demand()    at System.Net.AuthenticationManager.Register(IAuthenticationModule authenticationModule)    at

MWLSPXRMToolkitOnline.Plugins.AccountCreate.ExecutePluginLogic(IServiceProvider serviceProvider)    at MWLSPXRMToolkitOnline.Plugins.BasePlugin.Execute(IServiceProvider serviceProvider)

The action that failed was: Demand The type of the first permission that failed was:

System.Security.Permissions.SecurityPermission The Zone of the assembly that failed was: MyComputer

Not sensibly, when running in Sandbox mode you can't include references to other assemblies. You could try using ILMerge to combine the assemblies together, but if I was you I would take a different approach, e.g. pushing work to an external web service.

If using ILMerge to combine the assemblies together(as recommended by James Wood because when running in Sandbox mode you can't include references), use the '/copyattrs' parameter with ILMerge. If you have installed ilMarge in the project with NuGet package:

Editing the file in solution:ILMerge.props Change parameters:

<ILMergeAllowMultipleAssemblyLevelAttributes>true</ILMergeAllowMultipleAssemblyLevelAttributes>
<ILMergeCopyAttributes>true</ILMergeCopyAttributes>
