DotnetcoreSearch - No runtime is found

[SpeedysWorkingArray]

I have tried different approaches, but no runtime is found. Do I have to change anything in the structure?

<?xml version="1.0" encoding="UTF-8"?>
<Wix xmlns="http://wixtoolset.org/schemas/v4/wxs"
     xmlns:util="http://wixtoolset.org/schemas/v4/wxs/Util"

     xmlns:netfx="http://wixtoolset.org/schemas/v4/wxs/netfx">

  <Fragment>
    <netfx:DotNetCoreSearch
        MajorVersion="8"
        RuntimeType="desktop"
        Platform="x64"
        Variable="DesktopRuntime"
        Id="DesktopRuntimeId" />
        
    <Property Id="DesktopRuntimeVersion" Value="[DesktopRuntime]" />
    
    <CustomAction Id="LogDesktopRuntimeValue"
              Property="CustomLogMessage"
              Value="Desktop Runtime Value: [DesktopRuntime]" />
         
    <CustomAction Id="AbortInstallationIfNoDesktopRuntime"
                  Error="!(loc.DesktopRuntimeRequired)"
                  Execute="immediate"
                  Return="check" />                                      
  </Fragment>
          
<Package Name="$(var.ProductName) $(var.Application) ($(var.Platform))"
 .../>

...
   
    <InstallExecuteSequence>
      <Custom Action="LogDesktopRuntimeValue" Before="LaunchConditions" />
      <Custom Action="AbortInstallationIfNoDesktopRuntime" Before="LaunchConditions" Condition="NOT DesktopRuntime" />
    </InstallExecuteSequence>
  </Package>
</Wix>    

Looks like DotnetCoreSearch is not executing at all. Any ideas?

The thing that stands out to me is that Property elements author a row in the Property table. The Property table Value column is defined as type Text not type Formatted. This means you can't use [SOMEOTHERPROP] and expect it to get interpolated to the value of SOMEOTHERPROP.

You need to use a SetProperty element insetad. This authors a Type 51 Custom Action that can do what you want provided it's sequenced correctly.
