Json.NET 3.5 Update
Beta 3 of the Json.NET library is now available.  I’ve used Json.NET for serialization objects in ASP.NET MVC with great success. 

ASP.NET Menu + IE8 == SURPRISE!
Yeah, who knew that IE8 would cause problems?  To be fair, the ASP.NET Menu really produces awful, terrible, horrendous, other-negative-adjective HTML, so maybe IE isn’t to blame on this one.  On the plus side, there is a patch.  On the downside, you have to install the patch.

.NET’s Large Object Heap
Andrew Hunter has a very informative post about memory management in .NET.  I run into problems with the large object heap causing OutOfMemory errors quite frequently since I deal with information retrieval, which involves working with (sometimes very large) documents.  As it turns out, I didn’t really understand exactly what was going on until I read this article.  Thanks, Andrew!

Microsoft (Dis)connect?
Ayende has a very valid complaint about Microsoft Connect.  As one of the commenters pointed out, the problem could be that the right eyes aren’t the ones reviewing issues raised on Connect.

Microsoft releases Infer.NET Beta
Infer.NET is a .NET API for machine learning.  I haven’t had a chance to play with it yet, but it sounds very interesting.  According to the short video, they have developed it to be scalable to very large data sets (millions of objects), which is neat.  I’d love to see a real .NET alternative to Java’s Weka; maybe this can serve as a building block along that front.
