Can't build UWP with Uno Platform 3.3

[stefanolson]

Current behavior

Can't build UWP with Uno 3.3. After updating to the 3.3 templates and creating a new project and asked that I want to install a whole heap of things to visual studio which I did. At some point after that it's no longer building the UWP target in visual studio

Expected behavior

Should build

How to reproduce it (as minimally and precisely as possible)

Create a new project. Build. Error:
".nuget\packages\microsoft.net.uwpcoreruntimesdk\2.2.9\tools\CoreRuntime\Microsoft.Net.CoreRuntime.targets(136,5): error MSB3774: Could not find SDK "Microsoft.VCLibs, Version=14.0"."

Workaround

None. Attempted to repair visual studio as suggested here: microsoft/microsoft-ui-xaml#3620 (comment). But no different :-(

Thanks for the report.

How are your creating the templates ? Through the vsix or the dotnet new experience ?

[stefanolson]

vsix in Visual Studio create new project

Does building a standard UWP project work? If so, could you provide the binlog as well ?

[stefanolson]

Just tried. Sadly building UWP is completely broken :-( Not even a brand-new app will build. Wonder whether this was to do with installing visual studio 16.9 preview. I did manage to run a Uno 3.3 UWP app yesterday.

[stefanolson]

I've enclosed the log for a just a plain UWP app (to avoid all the other Uno projects confusing things). But does look like another visual studio rather than Uno issue :-(
msbuild.zip

Yes indeed, if an UWP app does not build, there's not much Uno can do... That being said, this library is part of the WinUI 3.0 Preview 3, if I'm not mistaken. Have you installed it (or not) ?

[stefanolson]

I think I installed an older version of the Win Ui Preview. I'll try and update to preview 3 in case it helps. Thanks.
