How to define wix variables as part of msbuild task in wix4

[svg2003]

Hi,

In wix3 there is ability to add new wix variables inside msbuild task as following:

<CreateProperty Value="MyNewWixVariable="some value";$(WixVariables)">
  <Output TaskParameter="Value" PropertyName="WixVariables" />
</CreateProperty>

And after use its value in wxs file like below:

In wix4 such ability seems missing. Can you please advice alternatives how to do it, or restore previous functionality back?

Define your WixVariables property in your .wixproj or use the BindVariable item instead.
