How can I make the Custom Task Pane Header Color more match the inner usercontrol ?
I already google this problem ,these are the search results:
（1） Add-in Express 【Third-Parties:not free】
（2） Shared Add-in 【find that:This project has been removed in Visual Studio 2012 This project is still available in Visual Studio 2010 and 2008 under (Other Project Types > Extensibility) 】
（3） public class Connect : Object, Extensibility.IDTExtensibility2, Office.IRibbonExtensibility, Office.ICustomTaskPaneConsumer 【from:https://learn.microsoft.com .Hard to execute ,hard to understand without a instance】
