R help - Oct 2010 - Any similar solution for C# (Integrating R with C++: Rcpp, RInside, and RProtobuf)

Friends -

I am pretty excited for the following talk and I was wondering
if there is a similar solution for C#. I googled but didn't find a 
good solution. Previously, I let C# to send R code to Rscript.exe.
But it is not an integrated solution.
