Here. From Mihies: The Oracle Data Provider for .NET (ODP.NET) features optimized data access to the Oracle database from a .NET environment. Unlike OLE DB .NET and ODBC .NET, ODP.NET is a native driver and does not use a data access bridge, which can reduce performance. ODP.NET allows developers to take advantage of advanced Oracle database functionality. The data provider can be used from any .NET language, including C# and Visual Basic .NET.

Here. TaskVision is a full-featured WinForms sample that supports auto-updating over the web and online and offline functionality, as well as some other cool .NET stuff. It includes most of the source for the client and the server as well as a lengthly write-up on just what makes it cool. Worth checking out as an alternative to href-exes (TaskVision requires one install and auto-updates after that).

Here. eXtensible C# provides a set of compile-time attributes to do things like inject code (like to check for a null value), analyze code at compile-time and even obfuscate. Very cool.

Here. From Sorin J: This may be yesterday's news, anyway, Microsoft has applied for a patent covering many .net related technologies.

Here. From David: A new microsoft sample that demonstrates the following: Application offline and online model Application update model via HTTP (no-touch deployment) Authorization to control user access to application features Data collision handling Printing and Print Preview Windows XP Themes Dynamic properties Localization support Accessibility support (limited) Forms authentication using a database for user names/passwords Asynchronous XML Web service class ADO.NET data access using SQL stored procedures Graphics development using GDI+ Integration between .NET Framework-based code and COM applications (COM interop)

Here. A nice summary of what's going on when you attempt to run two versions of .NET side-by-side.

Here. From Matthew Lewis: First of a series outlining the core namespaces and classes that cohesively implement the standards based XML processors in the Microsoft .NET Framework. This session will discuss each class in detail.

Here. It's nice to see that somebody is tracking and publishing bugs on my most favorite technology, although I suspect that many are as yet unlisted...
