Not many posts from me at present - we're heads down into our last coding milestone for V1.
Just wanted to point up a couple of bugs in the February CTP and the fixes for them.
Firstly, if you open the Tools\Options\TextTemplating page in Visual Studio, then it will fail and thereafter, any DSL Tools project will throw the following error.
Package Load Failure - ...TextTemplating.VSHost.OrchestratorPackage
The fix for this is a registry modification which Stuart has posted here.
Secondly, if you're trying to test deployment of a custom DSL onto machines that do not have the DSL Tools installed, you'll run into problems. The fix for this one is here.
