Answer 2

Remove unwanted attribute from plugin images.only select attribute that you need in the plugin.You can set it when you registering plugin(don't tick all attributes check box).remove security related attribute(owner, modified by, created on)

Answer 3

Some of you might get this error in the plugin steps when an organization is being migrated to CRM 2015.
Cause:
You change the ownership of the record in the record Pre-creation
Resolution:
Most solutions out there say about change the plugin to Post-operation stage, but this don't make sense for some of the actions/checks that your plugin could do.
So, what you could do is to check the pipeline stage before you run the assignment operation.

Sample code:
//Runs on the Pre-Validation step, when a Contact is created
if (context.Stage == 10)
{
if (!targetEntity.Attributes.Contains("parentcustomerid"))
{
throw new InvalidPluginExecutionException("Message to show....");
}
try
{
var accountOwner = (from a in orgServiceContext.AccountSet
where a.Id == targetContact.ParentCustomerId.Id
select a).Single();
targetEntity.Attributes["ownerid"] = new EntityReference("team", accountOwner.OwnerId.Id);
targetEntity.Attributes["owningbusinessunit"] = new EntityReference("businessunit", accountOwner.OwningBusinessUnit.Id);
}
catch
{
throw new InvalidPluginExecutionException("Message to show...");
}
}
Found another solution: Move your plugin step to Pre-Validation.
