如在键入"{x:Type local:}"/>时所讨论的那样，在此代码段中.智慧应该给出一个包含"CustomerDataProvider"的弹出窗口.但是就我而言，这不是我想要的，即我希望代码段像"{x:Type local:CustomerDataProvider}"一样.请帮助

in this code segment as discussed while typing this "{x:Type local:}" /> the intellisence should give a popup window which contain "CustomerDataProvider". but it is not coming in my case ie I want the code segment to be just like "{x:Type local:CustomerDataProvider}". Please help

推荐答案

没有遍历所有代码，但是如果问题仅仅是InelliSense没有提出任何建议，为什么不写正确的建议呢?手动输入.在许多情况下，Intellisense不会给出最新建议.

Didn''t go through all the code but if the problem is simply that the InelliSense isn''t making any suggestions, why not write the proper type by hand. There are several cases when Intellisense doesn''t give up-to-date suggestions.
