而且，好像也有其他人遇到同样的问题（点击“Q AND A”）。

有可能环境不支持，建议你也在上面扩展工具上问一下，看看扩展工具专家是不是有好的建议！
另外，既然大家也有遇到这个问题，你也可以向产品组提交一个反馈（可能需要英文提交）。

而且VS2015在win10上，目前可能还是有限制的。

Q: Will Visual Studio 2015 Preview support Windows 10 as support is not included in the release?
A:
No. Visual Studio Preview does not include yet the tools for developing Windows 10 applications. The existing Windows 10 release does not target developers and therefore the tools and SDK
are not yet available.
希望能帮到你！
