Visual Studio 2015 Auto Build

Question

I noticed that my app does not build automatically anymore: Is this new behaviour? Have I a setting which is incorrect?

Microsoft Visual Studio Community 2015
Version 14.0.24720.00 Update 1
Microsoft .NET Framework Version 4.6.01055

The project builds when I fix errors but error fixes are updated automatically in the error window.

Answer 1

将Error窗口设置为Build + IntelliSense。
