Microsoft.Windows.UI.Xaml.CSharp.targets was not found - VS17 - Last MRT Build

Hi, I come to you guys for help because I’ve been trying for some time to get the build portal to work at 100% without much success, I don’t know if it’s a bug or something wrong on my side.

I get the following error while MSBuild runs the command "C:\Program Files (x86)\Microsoft Visual Studio\2017\BuildTools\MSBuild\15.0\Bin\MSBuild.exe" "C:\Users\PROJECTPATH\UWP\PROJECTNAME.sln" /t:Build /p:Configuration=MASTER /p:Platform=x86

During the generation of an APPX from the solution build with the toolkit. I’m suspecting a path issue/something not installed that I missed, but I can’t find it sadly.

EDIT : I should mention that the files actually does not exist, nor it’s parent folder and that my sln file mentions Visual Studio 2015, that surprises me.

Cheers

Here’s the error :

I’ll be damned, I uninstalled a VS Build Tool version that I installed next to my VS17 installations this morning, and MRTK used VS17 MSBuild ( I just added it too, dunno if related ) and the appx build went AFAIK smoothly. At this point I don’t know if I had very poor look with my environment or if tuts we not explicit enough… But it looks like it’s gonna work. I’ll try to deploy this, I’ll keep you posted.

Thank you so much, this actually works. I have been banging my head on this issue for about a week, only to learn you just have to reinstall the build tool.
