[wix-users] Using Lux with Wix 3.11

[David Horton]

Hi all,

I was recommended to subscribe to mailing list and post my issue here.  Excited to join and be a part of this group.  Looking forward to contributing also as I learn things.

Which version of WiX are you building with?
(WiX version 3.11.1.2318)

Which version of Visual Studio are you building with (if any)?
(Visual Studio 2019 Community Edition version 16.2.3)

Which version of the WiX Toolset Visual Studio Extension are you building with (if any)?
(WiX Toolset Visual Studio Extension 1.0.0.4)

Which version of .NET are you building with?
(.NET version 4.8.03752)

Describe the problem and the steps to reproduce it.
I am attempting to add a unit test to my .wxs source file which I am editing in Visual Studio 2019 Community Edition IDE. I am creating it per the steps outlined at (https://wixtoolset.org/documentation/manual/v3/overview/lux.html):

<Fragment> <lux:UnitTest CustomAction="CheckOpenDentalInstalled" Property="SIMPLE" Value="[INSTALLFOLDER]" Operator="equal" /> </Fragment>

However, I receive the following error when trying to build the Wix Setup Project in Visual Studio, as well as when attempting to run Candle.exe from the command prompt: Not a valid source file; detail: 'lux' is an undeclared prefix.

When I add the namespace declaration to the top of the .wxs source file, the error goes away and the source compiles:

Before:

<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi">

After:
<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi" xmlns:lux="http://schemas.microsoft.com/wix/2009/Lux">

I follow steps to compile using candle with the -ext WixLuxExtension, it compiles to the .wxsobj. However when I run lux.exe command against the compiled source, I receive the following error:

lux.exe : error LUX8003 : No unit tests were found in given input files.

Any insight into this would be greatly appreciated as I am attempting to add unit testing to my Custom Actions in WiX.
