Actually I meant "Orchard" when I said "WebMatrix" not being ready, but I've removed that comment now. Actually my experience with Orchard CMS is currently better than with Umbraco or DNN.
There's a mismatch here... WebMatrix is a good starting point, and it has that enticing button to open the website in VS2010. So it's not surprising that someone like me would click it. I don't particularly care about the source code... I just
want an environment that has SVN. Also it's my understanding that MS want new developers to start with WebMatrix and gravitate to VS.
So it would seem to me that you would save a lot of scratched heads and logged discussions here if the Orchard "WebPI" package
did build ok in VS... is that possible?
Or, alternatively, there should be a way for you to signal in your smaller WebPI package that "it does not build in VS" so that WebMatrix knows not to display that button.
I note that there's nothing in your quote from the release notes that says "it will not compile" so I hope you will understand my confusion.
