Dynamic CRM Online 2015自定义工作流早期绑定错误

Question

I create a XRM.cs file from crmsvcutil.exe and refer to the url

Could not load file or assembly 'Microsoft.Xrm.Client

So I merge 'Microsoft.Xrm.Client' with my workflow assembly and register it in database at CRM online server.Then I got this error:

System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.UIPermission, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

at Xrm.XrmServiceContext.get_AccountSet()
at Mailer.SendMailDaily.Execute(CodeActivityContext executionContext)
The action that failed was:
InheritanceDemand
The type of the first permission that failed was:
System.Security.Permissions.UIPermission
The Zone of the assembly that failed was:
MyComputer  

Here is my code, Can anybody solve this?

IWorkflowContext context = executionContext.GetExtension<IWorkflowContext>();
IOrganizationServiceFactory serviceFactory = executionContext.GetExtension<IOrganizationServiceFactory>();
IOrganizationService service = serviceFactory.CreateOrganizationService(context.InitiatingUserId);
var xrm = new XrmServiceContext(service);
var customers = from c in xrm.AccountSet select c;

Answer 1

To be clear you mean this Microsoft assembly?

https://msdn.microsoft.com/en-us/library/microsoft.xrm.client.aspx

Why did you do that?

Just register your own plugin assembly.
