The title is a lie (sort of)... I don't know what the long time future of dasBlog is, but short term the following is going to happen. We will release a .NET 3.5 version soon (which is running on this blog now). We probably will release a .NET 4 version shortly following that. And when Visual Studio 11 is released in Beta, we will release a version of dasBlog for .NET 4.5.

New features? DasBlog is fine for my needs as is, if you have something specific you would like, please let us know. Depending on the complexity we might be able to put it in.

When you forward a generic type to another assembly [0] using the TypeForwardedTo attribute, you can’t specify the typeparameters. Instead the number of typeparameters in in the class definition depends the number of comma’s in definition.

using System.Runtime.CompilerServices;

[assembly: TypeForwardedTo(typeof(Destination.SomeClass))] // Non generic

[assembly: TypeForwardedTo(typeof(Destination.SomeClass<>))] // equivalent to SomeClass<T>

[assembly: TypeForwardedTo(typeof(Destination.SomeClass<,>))] // equivalent to SomeClass<T,U>

As both Jason and Soma blogged earlier, Visual Studio 2010 SP1 is released today.

MSDN subscriber can download Service Pack 1 today, everyone else has to have a little more patience until March 10, when they can download it from Microsoft downloads.

I’ve been doing a lot of development using Visual Basic in the past couple of months and there are some interesting features in the language which may or may not be very well known. Features that don’t have an equivalent in C#.

Default values for auto implemented properties.

Visual Basic support the option of setting a default value for a property, like you would in a field.

Public Property MyProp As Integer = 42

MSDN: Auto-Implemented Properties

Key properties in anonymous types

By defining properties in anonymous types as key properties, you can enable specific behavior for the equality behavior of these types. When an anonymous type contains key properties, then for both the Equals and the GetHashCode overridde is generated based on these key properties. Additionally the key properties are readonly, where normal properties are read/write.

Dim one = New With {.Name = "one", Key .No = 1}

Dim two = New With {.Name = "two", Key .No = 1}

' This is true because the key property for both instances of the same class is equal



Filtered exceptions

Adding a filter to a catch expression in a try/catch block allows you to direct the exception handling based on a condition. This is especially useful when you’re catching a general exception, which should be handled differently based on the error code it contains.


Throw New COMException()

Catch ex As COMException When ex.ErrorCode = 0

Console.WriteLine("y = 0")

Catch ex As COMException When ex.ErrorCode <> 0

Console.WriteLine("y <> 0")

End Try

MSDN: Try...Catch...Finally Statement

Today Jason Zander announced the availability of Visual Studio 2010 SP1 Beta on his blog. It’s available today for MSDN subscriber and will be general available on Thursday.


This service pack consists for the most part of fixes for issues logged through the connect site, but one noticeable new feature is the inclusion of the VB runtime compiler switch. This allows developers to ‘embed’ the Visual Basic Runtime in their assemblies, similar to No-PIA. The compiler figures out which parts of the runtime your program actually uses and embeds only these parts in the generated assemblies.


Download the service pack and report any issues you encounter, that’s the only way we can make it better for you. (Even if the issues you encounter aren’t fixed in the service pack, we still look at them and consider them for a next version of Visual Studio).

So, it's been over a year..... which I know is a long time, but much has happened in a very short time, so blogging was one of the casualties. But now that things have settled down, I´m back!
So what has happened:
  • After interning at Microsoft last summer, I got a job offer for a position in the C# IDE QA Team, which I accepted.
  • I married my wife
  • We moved to the US (See 1)
  • Found a place to live
  • Worked hard on finishing my Bachelor's degree
  • Helped finish Visual Studio 2010 (a little)
What's next? We'll start working on dev 11 (VS v.Next) soon, which will be exciting since it's the first time I'll be involved in the entire product cycle from planning till release. Hopefully a lot more blogging/tweeting (140 chars should be enough for everyone).
btw. I'm posting this via posterous, it should show on my regular blog. (
