page opening in solution explorer instead of main tab in VS 2013

Question

Before when I double-clicked an item in Solution Explorer (VS 2013), it would open it in the main tab (I don't know if this is the name, but I hope you got the idea of what I'm referring to). Now, for some reason, it opens inside the Solution Explorer and I have to drag it to the "main" tab. Is there a way to restore to the original way it was before?

UPDATE

I just realized what is happening. Double clicking the document opens it in the main tab, as usual, however, if the app is running in the browser, double-clicking will open it in the Solution Explore window. I think this is the normal behavior and now I understand it.

Answer 1

右键单击“解决方案资源管理器”窗口标题，然后选择Dock命令。

Answer 2

好吧，到目前为止，我发现，除了拖动以外，可用的选项是右键单击页面，然后选择以下选项：“移至主文档组”或“移至上一个选项卡组”（如果前者不可用） 。
