Unable to build the package

[inner214]

On an attempt to compile the installation package, I'm getting an error saying:

"WIX0200 The Package element contains an unhandled extension element 'WixUI'. Please ensure that the extension for elements in the 'http://wixtoolset.org/schemas/v4/wxs/ui' namespace has been provided."

The code snippet responsible for UI declaration is as follows:

xmlns:ui="http://wixtoolset.org/schemas/v4/wxs/ui"
...
<ui:WixUI Id="WixUI_Minimal"/>

When I'm trying to open the schema itself, I'm getting the error saying that the page was not found.

Any ideas how to get it solved? Thanks!

Did you add PackageReference to the UI extension?

Yes, I did. Here is what I have in my wixproj file

I'm a bit confused the fact I'm unable to open the schema definition itself. Out of curiosity, are you able to open it up following the link below http://wixtoolset.org/schemas/v4/wxs/ui ?

Alright, it looks like I've solved the issue. It appears one of the recent Visual Studio updates somehow damaged FireGiant Heatwave installation on my local machine. I've got it re-installed and the solution now builds perfectly well.
