New Post: Installing Static Data Types with Dependencies via Package

I've developed a package that contains two static data types (IClient and IClientHour). One of the static data types (IClientHour) has a dependency on the other static data type (IClient).

I'm attempting to add the data types to my instance of Composite C1 via a package. I would like to leverage the DataTypePackageFragmentInstaller and DataTypePackageFragementUninstaller classes to register and drop my data types with the package.

The problem I'm facing is that the package is failing to validate and spits out the following error:

Failed to build data type descriptor for interface 'Builders.Data.IClientHour' The type 'Builders.Data.IClient' could not be found.

Both types are in a DLL that I am copying to the CMS via the FilePackageFragmentInstaller. In searching the forum I found a suggestion of adding assemblyLoad="true" to the File element for the assembly that contains the types. This suggestion did not solve the issue I'm facing.

Below is a condensed version of my install.xml displaying the sections related to the data types and assembly:

<mi:PackageFragmentInstallers>
        <mi:Add installerType="Composite.Core.PackageSystem.PackageFragmentInstallers.FilePackageFragmentInstaller, Composite" uninstallerType="Composite.Core.PackageSystem.PackageFragmentInstallers.FilePackageFragmentUninstaller, Composite">
            <Files>
                <File sourceFilename="~\Bin\Builders.dll" targetFilename="~\Bin\Builders.dll" allowOverwrite="false" assemblyLoad="true" />
            </Files>
        </mi:Add>

        <mi:Add installerType="Composite.Core.PackageSystem.PackageFragmentInstallers.DataTypePackageFragmentInstaller, Composite" uninstallerType="Composite.Core.PackageSystem.PackageFragmentInstallers.DataTypePackageFragmentUninstaller, Composite">
            <Types>
                <Type name="Builders.Data.IClient, Builders" />
                <Type name="Builders.Data.IClientHour, Builders" />
            </Types>
        </mi:Add>
    </mi:PackageFragmentInstallers>
</mi:PackageInstaller>

Any assistance/suggestions with accomplishing this task is greatly appreciated.
