I am reading about new features in Visual Studio 9.0 (Orcas) (while I am playing with it :) ) and I found there is a new feature in Visual Basic called Relaxed Delegates.
What this means!? For instance you can convert methods to delegate even when methods doesn;t have all parameters (if not used)
This is the sample from Amada Silver:
Another great feature that you’ll
notice in Beta1 is Relaxed Delegates. In short, relaxed delegates
are a way to extend VB’s implicit conversions to delegate types. With relaxed
delegates, you can write the following code:
Private Sub Button1_Click(ByVal
sender As Object,
ByVal e As
You can even omit *all* of the event
arguments if your method body doesn’t need them. This improves readability
without compromising type safety:
Option Strict On
Public Class Form1
Private Sub Button1_Click() Handles
A bit unfair to C# but still - this is Visual Basic :)
Today MS signed off on the Beta 1 release for Visual Studio “Orcas” and .NET FX 3.5.
Go and check here.
Visual Studio Code Name “Orcas” Beta 1
Visual Studio code name "Orcas" is the next generation development tool for Windows Vista, the 2007 Office system, and the Web. Beta 1 consists of multiple releases including, Visual Studio Professional Edition, Visual Studio Team Suite and Visual Studio Team Foundation Server, which are available as installation media ISO images you can use to install the products. Alternatively, you can download VPC images with the software pre-installed. In addition, you can download prerelease versions of Visual Basic Express, Visual C++ Express, Visual C# Express, and Visual Web Developer.
For a better download experience, MSDN Subscribers should use MSDN Subscriber Downloads for both installation media ISO images and VPC images.
This news came from Soma
Assemblies of next version of .NET Framework are divided in two groups - "green bits" and "red bits" as they are called inside Microsoft.
The red bits include all the libraries that shipped before as part of the .NET Framework 2.0 and 3.0 (such as mscorlib.dll and system.dll). To maintain a high assurance of backward compatibility for Visual Studio "Orcas," changes in the red bits have been greatly limited.
The green bits assemblies are the brand new libraries with additional classes that work on top of the red bits assemblies. Most of the classes listed in this column are in the green bits assemblies (such as system.core.dll), with a few involving limited changes in the red bits assemblies.
The CLR's contributions to the new libraries include:
- A new add-in hosting model, which was discussed in the last two editions of CLR Inside Out
- Support for the Suite B set of cryptographic algorithms, as specified by the National Security Agency (NSA)
- Support for big integers
- A high-performance set collection
- Support for anonymous and named pipes
- Improved time zone support
- Lightweight reader/writer lock classes
- Better integration with Event Tracing for Windows® (ETW), including ETW provider and ETW trace listener APIs
There are also new crypto classes that covers Suite B set of cryptographic algorithms.

C# Community Program Manager Charlie Calvert posted rough schedule about public chats with C# team
In the April/May time frame there will be three public chats by the C# Team.
April 23, 2007, 11 AM Pacific Time C# Visual Studio IDE Chat: Talk about C# IntelliSense for LINQ. Discuss what else is planned for Visual Studio Orcas. Plus: Code snippets, enhanced IntelliSense, type colorization, refactoring, improved code navigation, metadata as source, Edit and Continue and all the other great new C# IDE features in Visual Studio 2005. There's a lot to talk about! It's your choice! Join the C# IDE team for a chat completely directed by your questions.
May 7, 2007, 11 AM Pacific Time Compiler and Language Chat: C# Language Chat. Want to know more about anonymous delegates in C# 2.0, or our design rationale for them? Have some questions about our current thinking on C# 3.0 and LINQ? Perhaps you'd like to share your ideas with other C# users or the C# language team. Join the C# team chat for an opportunity to do all that and more!
May 21 2007, 11 AM Pacific Time LINQ to SQL Chat: The LINQ Project is a part of the next version of Visual Studio, code named Orcas. LINQ will provide a set of extensions to the .NET Framework that encompass language-integrated query, set, and transform operations. LINQ to SQL is a component of LINQ which allows access to data stored in relational databases. We’re actively designing and developing this technology - show up and join the LINQ to SQL team to participate in that process or just get a better understanding!
Luke Hoban, Program Manager for the C# Compiler posted blog article how is schedulled job for C# 3.0 compiler. This show what are new things and when we could expect to touch them:
Our first goal was to get the most fundamental new language features implemented, so we could begin building LINQ applications with the Orcas compiler as early as possible. Many of the features in this first set were also chosen because they were pre-requisites for implementing some of the later language features. For example, lambdas were important to get in early, because the conversion of lambdas to expression trees depended on this. Here's what we built first:
- Local Variable Type Inference (var)
- Object Initializers
- Extension Methods (usage)
For our second milestone, our goal was to replace the C#3.0 prototype compiler that we had shipped with the May 2006 CTP. When we finished this milestone, we actually moved all of the teams internally who were using C#3.0 over to use the Orcas C# compiler. This required implementing:
- Lambdas bound to Expression Trees
- Extension Methods (definition)
- Collection Initializers
- Anonymous Types
- Query Expressions
The third milestone was shorter, and our goal for this milestone was to get to a good state for the first Beta. The results of this milestone are what you'll see in the Orcas February/March CTP and the first Orcas Beta. We also implemented one of the most requested language features in the history of C# - auto-implemented properties!
- Auto-Implemented Properties
- Enhancements to Collection Initializers
- Non-language features, such as debuggability improvements
We're now working on the last feature milestone for Orcas. We're finishing off with one more language feature and a lot of work to improve compiler fundamentals, such as error messages and performance. Note that this work won't make it into the first Beta:
- Partial Methods
- Compiler Error Message Improvements
- Compiler Performance
- Compiler Generated IL Performance
It seems most of the features are implemented and we could see them in CTPs. We can touch most of them except Partial Methods. It looks like MS shaped the main VS Orcas features and they will shine them in next months before they release version 9.
Visual Studio Codename "Orcas" timetable was released on MSDN2.
Here is it:
Visual Studio code name "Orcas"
In addition to developer productivity improvements and new supported platforms and technologies in Visual Studio, Visual Studio code-named “Orcas” release will include the following new scenarios, features and improvements to Visual Studio Team System.
- Beta 1 - 2nd Quarter, CY 2007
- Beta 2 - Mid-year CY 2007
- RTM - TBA
It seems we will have more stable releases soon :)
