Hi Nathan
Today I've been playing with QLNet and ASP and have got a proof of concept
going. I've just used the FixedRateBond class so far and have essentially
modelled an interest only mortgage with it.
I have not had a look at your code yet, but I reckon that for my purposes I
might take your C++ code and port it to the C# QLNet project onto a branch,
if you're OK with that. I still need to finalise with the owners of QLNet
about how best to do that.
