"Build Solution" won't detect modified files and won't compile anything if there is an earlier compilation available. "Rebuild Solution" will work. ### Steps to reproduce: Create a new project, compile it, change output from Hello World! to something else, do a Build Solution and run it. ### Expected behavior: New text should be visible. ### Actual behavior: "Hello world!" is displayed. ### System VS2015, rustc 1.14.0, VR 0.1.2
