Bind package version to assembly version

[forrma]

My Package.wxs looks like that:

<Wix xmlns="http://wixtoolset.org/schemas/v4/wxs">
    <Package Name="MyProduct" Manufacturer="MyCompany" Version="1.0.0.0" UpgradeCode="5b5b3d00-f28e-4f7b-a178-3b5dee94e0b2">
        <MajorUpgrade DowngradeErrorMessage="!(loc.DowngradeError)" />

        <Feature Id="Main">
            <ComponentGroupRef Id="ProductComponents" />
        </Feature>
    </Package>
</Wix>

Now I want to bind the property 'Version' (currently set to "1.0.0.0") to the AssemblyVersion of my product. I have tried different approaches, unfortunately without success.

I also tried to add the version to the msbuild, unfortunately also without success:

msbuild MyProduct.Setup.sln /property:Configuration=Release /property:SoftwareVersion=%SoftwareVersion% -p:AssemblyVersion=%SoftwareVersion% -p:Version=%SoftwareVersion% -p:FileVersion=%SoftwareVersion%

Thanks a lot.

WiX supports user defined variables that you can use for this purpose. You aren't too far off...see this stackoverflow answer and the WiX documention here. The stackoverflow page also describes how you can use binder variables if you'd prefer.
