Using Wix to generate an MSI - visual-studio-2012

Question

I am using Wix 3.8 to create an MSI installer for a Visual Studio project I have created. I followed this simple tutorial but even with this simply Wix project I am getting errors. Here is My
I have added my VS2012 project as a reference to my Wix Installer.
Here is my Product.ws file:
<?xml version="1.0" encoding="UTF-8"?>
<Wix xmlns='http://schemas.microsoft.com/wix/2006/wi'
xmlns:iis='http://schemas.microsoft.com/wix/IIsExtension'>
<Product Id="*" Name="MyProjectInstaller2" Language="1033" Version="2.0.0.0" Manufacturer="Company" UpgradeCode="7f5b63be-bdad-4cc9-b4df-b3f1648c0539">
<Package InstallerVersion="200" Compressed="yes" InstallScope="perMachine" />
<MajorUpgrade DowngradeErrorMessage="A newer version of [ProductName] is already installed." />
<MediaTemplate />
<Feature Id="ProductFeature" Title="MyProjectInstaller2" Level="1">
<ComponentGroupRef Id="ProductComponents" />
</Feature>
</Product>
<Fragment>
<Directory Id="TARGETDIR" Name="SourceDir">
<Directory Id="ProgramFilesFolder">
<Directory Id="INSTALLFOLDER" Name="MyProjectInstaller2" />
</Directory>
</Directory>
</Fragment>
<Fragment>
<ComponentGroup Id="ProductComponents" Directory="INSTALLFOLDER">
<!-- TODO: Remove the comments around this Component element and the ComponentRef below in order to add resources to this installer. -->
<!-- <Component Id="ProductComponent"> -->
<File Source="$(var.MyProject.TargetPath)" />
<!-- </Component> -->
</ComponentGroup>
</Fragment>
</Wix>
When I compile this, I get the following error:
The ComponentGroup element contains an unexpected child element 'File'.
I have searched the bowels of the internet for a solution to this very basic problem. Why is VS2012 not recognising the element?

Answer 1

You should follow next hierarchy: ComponentGroup -> Component -> File and etc. In your example i suggest to you to put File element into separated component and then add this component into ComponentGroup. Try something like this:
<Component Directory="YOUR-DIRECTORY" Guid="your-guid" Id="SomeComponent">
<File Source="$(var.MyProject.TargetPath)"/>
</Component>
<ComponentGroup Directory="INSTALLFOLDER" Id="ProductComponents">
<ComponentRef Id="SomeComponent"/>
</ComponentGroup>

Answer 2

Read the TODO comment right above your <File Source>
You need to remove the comments around <Component Id="ProductComponent"> and </Component>.
