Include MajorVersion etc in filename (OutputName) when building MSI file (wix project)

Question

In my Defines.wxi I have:

<?define MajorVersion="1" ?>
<?define MinorVersion="08" ?>
<?define BuildVersion="11" ?>

In my MyProject.Setup.wixproj I have:

<OutputName>MyProject</OutputName>
<OutputType>Package</OutputType>

Is it possible to include the version variables in the filename somehow, so that my file can be named MyProject.1.08.11.msi?

This didn't work (no such variable is defined):

<OutputName>MyProject-$(MajorVersion)</OutputName>
<OutputType>Package</OutputType>

This didn't work (no such variable is defined):

<Target Name="AfterBuild" Condition="'$(Configuration)' == 'Release'">
    <Copy SourceFiles="$(OutputPath)$(OutputName).msi" DestinationFiles="C:\$(OutputName)-$(MajorVersion).msi" />
</Target>

It seems very clear to me that $(MajorVersion) is not the correct way of fetching the definition from the Defines.wxi file. What is?

Update

I tried to put this in MyProject.Setup.wixproj:

<InstallerMajorVersion>7</InstallerMajorVersion>
<InstallerMinorVersion>7</InstallerMinorVersion>
<InstallerBuildNumber>7</InstallerBuildNumber>

...

<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Release|x86' ">
    <OutputPath>bin\$(Configuration)\</OutputPath>
    <IntermediateOutputPath>obj\$(Configuration)\</IntermediateOutputPath>
    <DefineConstants>PrebuildPath=..\..\obj\prebuild\web\;InstallerMajorVersion=$(InstallerMajorVersion);InstallerMinorVersion=$(InstallerMinorVersion);InstallerBuildNumber=$(InstallerBuildNumber)</DefineConstants>
</PropertyGroup>

And this in Defines.wxi:

<?define MajorVersion="$(var.InstallerMajorVersion)" ?>
<?define MinorVersion="$(var.InstallerMinorVersion)" ?>
<?define BuildVersion="$(var.InstallerBuildNumber)" ?>
<?define Revision="0" ?>
<?define VersionNumber="$(var.InstallerMajorVersion).$(var.InstallerMinorVersion).$(var.InstallerBuildNumber)" ?>

Didn't work either. Got these error messages:

• The Product/@Version attribute's value, '..', is not a valid version. Legal version values should look like 'x.x.x.x' where x is an integer from 0 to 65534.
• The Product/@Version attribute was not found; it is required.

This is what I ended up with, and it works!

Setup.Version.proj

<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
    <PropertyGroup>
        <InstallerMajorVersion>55</InstallerMajorVersion>
        <InstallerMinorVersion>66</InstallerMinorVersion>
    <InstallerBuildVersion>$(BuildNumber)</InstallerBuildVersion>
        <InstallerBuildVersion Condition="$(InstallerBuildVersion) == ''">0</InstallerBuildVersion>
  </PropertyGroup>
</Project>

MyProject.Setup.wixproj

<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="4.0" DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <Import Project="Setup.Version.proj" />
  <PropertyGroup>
    <OutputName>MyProject_$(InstallerMajorVersion)_$(InstallerMinorVersion)_$(InstallerBuildVersion)</OutputName>
    <OutputType>Package</OutputType>
    <DefineConstants>InstallerMajorVersion=$(InstallerMajorVersion);InstallerMinorVersion=$(InstallerMinorVersion);InstallerBuildVersion=$(InstallerBuildVersion)</DefineConstants>
    ...

Defines.wxi

<?define MajorVersion="$(var.InstallerMajorVersion)" ?>
<?define MinorVersion="$(var.InstallerMinorVersion)" ?>
<?define BuildVersion="$(var.InstallerBuildVersion)" ?>
