Visual Studio 2005 SDK March 2006 CTP
Time to update your CTP bits with the latest greatest, Visual Studio 2005 SDK March 2006 CTP. Pedro Silva mentioned in the Domain-Specific Language Tools section of the MSDN Forums that there are no new DSL Tools changes in this release.
This still means I have to have the latest bits on my box right :D
update (thanks to Claudio Perrone):
Just beware of the fact that designers created with the February CTP won't load straight away with the March CTP, although they could be easily fixed. I just spoke to Eamon O'Tuathail and he found that the problem is that the March '06 CTP VS SDK files are under
C:\Program Files\Visual Studio 2005 SDK\2006.03 whereas the February '06 CTP files are under: C:\Program Files\Visual Studio 2005 SDK\2006.02. So to fix the problem, open up designer.csproj in the designer folder in your old solutions, find "2006.02" and replace it with "2006.03", and everything will work. New projects created with the March '06 CTP will have the correct settings and don't need manual updates.
