Unity2018VS问题

There's an issue with the VSTU (visual studio tools for unity) for some reason it is not being updated when you install Unity 2018, the people at Unity says this is a Microsoft's issue, so filing a bug report will have no effect. You can verify which version you have on the "About Unity" window, you should have at least 3.5.0.2, if you have an earlier version you can download the new version here.
