Unresolved reference to symbol 'Property:NETFR

Question

I am getting an error when building an app in TFS 2010. Unresolved reference to symbol 'Property:NETFRAMEWORK45' in section 'Product:*'. This is for Wix 3.9

The Wix package has NetFxExtension referenced. I can build the wix on my local machine fine, but when I go to build it through TFS I get the error. Can anyone help me figure this out? I have the below code that is causing the error.

<PropertyRef Id="NETFRAMEWORK45"/>
<Condition Message="This application requires .NET Framework 4.5. Please install the .NET Framework 4.5 then run this installer again.">
  <![CDATA[Installed OR NETFRAMEWORK45]]>
</Condition>

Answer 1

You have to include the WixNetFxExtension in your project, in up to 3 places

1. in the Wix element of your wxs file, add the namespace xmlns:netfx="http://schemas.microsoft.com/wix/NetFxExtension"

2. Add a reference to WixNetFxExtension.dll in your project

3. If you are building manually using light.exe, you also need to add -ext WixNetFxExtension to your command line
