应该是如下：
[ExternalDataExchange]
public interface IBugFlowService
{
event EventHandler<BugAddedArgs> BugAdded;
void AssignBug(Bug bug);
}

public class BugFlowService : IBugFlowService
{
public event EventHandler<BugAddedArgs> BugAdded;

public void AssignBug(Bug bug)
{
Console.WriteLine("Assign a bug {0} to developer", bug.Title);
}

public void CreateBug(Guid instanceID, Bug bug)
{
BugAddedArgs arg = new BugAddedArgs(instanceID, bug);
EventHandler ev = this.BugAdded;
if (ev != null)
{
ev(null, arg);
}
}
}

提示错误: Error : The event BugAdded has to be of type EventHandler where T derives from ExternalDataEventArgs

我确定 BugAddedArgs 继承 ExternalDataEventArgs : EventArgs
