Sorry for the rather large delay in this week’s NServiceBus Weekly. Things have been rather hectic lately (see here, here and here) but I’m trying to get back to the normal schedule in the next episode.

Unfortunately this week’s NServiceBus Weekly is running little late. But fear not, it will get published in the near future.

I today received my copy of Martin Fowler’s Domain-Specific Languages. Quick browsing seems to point out that this book was well worth the investment.

As a side note, Amazon.co.uk has quite a nice selection of programming books in discount. The discounts have made me little worried that I may have to buy a larger bookshelf in the near future.

NServiceBus is moving forward. The trunk version now targets the .NET Framework 4.0 by default.
