How to make ExcelDna functions from Nuget.org package visible in the package user's Excel session

I have created a Nuget.org package, with the following (abridged) code:

namespace MyNugetPackageNS    module MyNugetModule =         open ExcelDna.Integration        // this function is NOT seen in the package user's Excel session        [<ExcelFunction(Category="Test", Description="Add 1.")>]        let plusOne ([<ExcelArgument(Description= "Value.")>] value: double) : obj =             value + 1.0 |> box

I was hoping that if a user installs the package and adds it into his own library, all the Excel functions defined in the package (e.g. plusOne) would automatically be visible within Excel, but it isn't the case. It seems that the user has to "wrap" the package Excel functions in order to make them visible in Excel, e.g. :

namespace UserNS    module UserModule =         // need to install the nuget package from Nuget.org        open MyNugetPackageNS.MyNugetModule        open ExcelDna.Integration        // this function is seen in the package user's Excel session        [<ExcelFunction(Category="Test", Description="Add 1.")>]        let plusOne2 ([<ExcelArgument(Description= "Value.")>] value: double) : obj =             MyNugetModule.plusOne value

My question : Is there a way to make the package's Excel functions automatically "visible" in the package user's Excel session, without wrapping each function before hand?
