[wix-users] MSBuild daily build error

[Dima Vasilkov]

Hello,

I have an existing WiX project that I am setting up for daily builds
following the instructions at
https://wixtoolset.org/documentation/manual/v3/msbuild/daily_builds.html.
However I am getting an issue compiling a custom action. For some reason
msbuild is using candle to try to compile the .cs file

Here is the relevant section from .csproj
  <ItemGroup>
    <Compile Include="CustomAction.cs"/>
    <Compile Include="Properties\AssemblyInfo.cs"/>
    <Content Include="CustomAction.config"/>
  </ItemGroup>

Here is msbuild output
