Am having a bit of an issue with WiX variables this a.m. which I'm hoping
someone can clue me in on. In a large Visual Studio solution, there are these
two projects called "Common.csproj", each referring to logic in different
namespaces, each in different physical folders. When setting the File tag's
Source attribute to a WiX variable, we run into a problem. The syntax for the
variable for both projects is as follows:
$(var.Common.TargetDir)
In order to solve this problem, we looked at the .wixproj file's schema,
wherein we have a series of ProjectReference tags. Beneath the
ProjectReference node, there's a Name tag - presumed to contain the string
referred to by the WiX toolset to identify the project name within the WiX
variable syntax. Consequently, we changed our .wixproj as follows (note the
<Name> tag content):
58 <ProjectReference Include="..\..\..\src\Service\Common\Common.csproj">
59 <Name>ServiceCommon</Name>
60 <Project>{7b6ebb1f-3b75-4497-85fb-e524fc9486fc}</Project>
61 <Private>True</Private>
62 </ProjectReference>
63 <ProjectReference Include="..\..\..\src\Shared\Common\Common.csproj">
64 <Name>SharedCommon</Name>
65 <Project>{13736794-cc44-4834-86a6-9733ba4c2089}</Project>
66 <Private>True</Private>
67 </ProjectReference>
Ordinarily, the <Name> tags would have contained strings like "Common
(Shared\Common)" and "Common (Service\Common)"; and these strings would have
appeared within the References node of the WiX project. Instead "SharedCommon"
and "ServiceCommon" now appear in the References folder, as they do in the
listing above.
However, when building the WiX project from within Visual Studio, we're still
seeing the same original error we had when we'd first started building using
diplicate $(var.Common.TargetDir) strings in our .wxs file:
candle.exe(0,0): error CNDL0001: Item has already been added. Key in
dictionary: 'Common.Configuration' Key being added: 'Common.Configuration'
Done building project "Sonora.wixproj" -- FAILED.
The -d arugments used when candle.exe is run by the build still use the
"Common" string, suggesting that WiX is actually not looking at the .wixproj
file's ProjectReference\Name nodes for the strings used as WiX variable names -
it's simply using the project file name, looks like.
Can anyone verify this? Further - can anyone suggest an alternative approach
for handling duplicate project names (if indeed any approaches exist, other
than telling all your devs to use unique project names in each solution)?
Gratefully,
RH
