I've had several requests in the past about supporting Visual Studio Express editions. The response has always been that Microsoft doesn't allow express editions to use extensions which was true. However, that appears to have changed recently and the newer Express editions do appear to support extensions (i.e NuGet and NodeJS). As such, Investigate to see how its done and if the SHFB extension will work properly in the various VS 2013 Express editions.
Comments: As it turns out the NuGet and NodeJS packages were developed by Microsoft and they made changes to the Express editions to allow them to run. So, the bottom line remains the same. Third-party packages cannot be used in Visual Studio Express editions. Attempts to use the product IDs from the packages noted above will allow them to get installed but they will be denied access to run.
