Terminal: Failed to build latest upstream

[Soumil07]

Environment

Windows build number: Microsoft Windows [Version 10.0.18362.116]
Windows Terminal version (if applicable): 83b139596fdbf0073655efd086b25172d4e578b1 (Git)

Any other software?

Steps to reproduce

Pull the latest commit, and build with VS2017.

Expected behavior

It builds correctly.

Actual behavior

1 error while building:

Severity    Code    Description Project File    Line    Suppression State
Error   C2039   'LastTabClosed': is not a member of 'winrt::TerminalApp::App'   WindowsTerminal c:\users\soumil\documents\terminal\src\cascadia\windowsterminal\apphost.cpp 73

@soumil07 that's weird, it looks like something is missing from the c++/winrt-generated headers. would you mind trying a full clean build?

@Soumil07 Check the full build output for errors. My experience was that some of the UWP-related projects won't get built with VS2017 if you don't have every single dependency installed you'll get build errors exactly like the one described. In particular, if you're using the VS2017 IDE, look for little warning icons next to the various projects at the bottom of the solution tree about a failure to load the project.

Same happened, but it was due to not rebuilding all Terminal projects before WindowsTerminal, try rebuilding them one by one.

[Soumil07]

A fresh rebuild works, so I'll close this - but I'd like to know what caused the build errors on pulling latest and rebuilding. I pulled the repo, nuget restored it and built it. Did I miss a step?

Same error, clean & rebuild didn't help:
