How to upgrade to RC1

[chrpai]

I see nuget getting updated packages and I'm eargly champing at the bit to try it. How do we use the new version? I don't see any project properties in HeatWave. I tried updating the .wixproj manually but it just says:

<Project Sdk="WixToolset.Sdk/4.0.0-rc.1">`
  <ItemGroup>
    <PackageReference Include="WixToolset.Iis.wixext" Version="4.0.0-rc.1" />
    <PackageReference Include="WixToolset.UI.wixext" Version="4.0.0-rc.1" />
    <PackageReference Include="WixToolset.NetFx.wixext" Version="4.0.0-rc.1" />
  </ItemGroup>

C:\Github\Test\Installer\Test\Test.wixproj : warning MSB4240: Multiple versions of the same SDK "WixToolset.Sdk" cannot be specified. The previously resolved SDK version "4.0.0-preview.1" from location "C:\Github\Test\Installer\TestMM\TestMM.wixproj" will be used and the version "4.0.0-rc.1" will be ignored.

We're still in the process of updating everything. Wait until you see an announcement on News for WiX v4 or FireGiant's blog for HeatWave to know that everything is in place.
