Twelve Core Processors in 2010

The AMD Server Workstation Roadmap lists processors with 6-core (Istanbul, 2009), and twelve-core (Magny Cours, 2010).
Parallel computing is becoming more and more important, e.g. Parallel LINQ.

Professional C# 2008

Professional C# 2008 is here! It contains 1800 pages although some chapters like .NET Remoting have been removed.
The sixth edition was changed to include C# 3.0 and .NET 3.5!
All the chapters of the book were changed to the new C# 3.0 syntax. Lambda expressions can be useful in many different cases.
A big focus of the book is into .NET 3.0 and 3.5. While the previous edition had one chapter about WPF, this edition gives you a lot more information. The same is true for WCF and WF. Beside having changes in all chapters to the new C# 3.0 syntax, LINQ has some dedicated chapters: 11 - Language Integrated Query; 27 - LINQ to SQL; 29 - LINQ to XML. You can also find a preview on the ADO.NET Entity Framework in appendix A. For ASP.NET 3.5, ASP.NET AJAX can be found in chapter 39. And much more! All you need for C# 3.0 and core information about the complete .NET Framework 3.5.

XAML Intellisense in Visual Studio 2008 - Fix after installation of the Windows SDK

Writing WPF applications I prefer using the XAML editor instead of the designer. With the help of Visual Studio 2008 intellisense this can be done really quick!

Now intellisense for XAML was broken - the solution posted by Brett Kilty (a missing path to the TextMgrP COM Library): Intellisense broken in all WPF applications

LINQ to XSD Alpha 0.2

It took some time after the first alpha (which was available for Beta 1 of Visual Studio 2008) - now a new version of LINQ to XSD is here: LINQ to XSD Alpha 0.2

C# v.next

C# is a changing language. C# 1.0 was all about core component-support. With C# 2.0 generics have been added. C# 3.0 added LINQ and extensions that are very useful with LINQ such as extension methods, object initializer, collection initializer, anonymous types....

What about the next version of C#?
One important part is using of types defined by dynamic languages such as IronRuby or IronPython.

The C# team considers the keyword dynamic that's shown in the blog of Charlie Calvert: Future Focus 1: Dynamic Lookup

LINQ with joins

Dan Wahlin posts about LINQ and Lambdas and Sprocs... Oh My! With his post he defines a complex LINQ query to join several tables from the Northwind database:

public IEnumerable GetOrderDetails(int orderID) {
  NorthwindDataContext db = this.DataContext;
  IEnumerable orderDetails =
    from o in db.Orders
    where o.OrderID == orderID
    join s in db.Shippers on o.ShipVia equals s.ShipperID
    join od in db.OrderDetails on o.OrderID equals od.OrderID
    join p in db.Products on od.ProductID equals p.ProductID
    join supplier in db.Suppliers on p.SupplierID equals supplier.SupplierID
    let total = od.Quantity * od.UnitPrice
    select new OrderDescription
    {
      Product = p.ProductName,
      Quantity = od.Quantity,
      ShipperName = s.CompanyName,
      Total = total,
      UnitPrice = od.UnitPrice,
      SupplierName = supplier.CompanyName
    };
  return orderDetails;
}

Instead of using joins with the LINQ query expression it is also possible to use compound from and access shipper and supplier (with a * to 1 relation) directly:

public IEnumerable GetOrderDetails(int orderID)
{
  NorthwindDataContext db = this.DataContext;
  IEnumerable orderDetails =
    from o in db.Orders
    where o.OrderID == orderID
    from od in o.OrderDetails
    let total = od.Quantity * od.UnitPrice
    select new OrderDescription
    {
      Product = od.Product.ProductName,
      Quantity = od.Quantity,
      ShipperName = o.Shipper.CompanyName,
      Total = total,
      UnitPrice = od.UnitPrice,
      SupplierName = od.Product.Supplier.CompanyName
    };
  return orderDetails;
}

I think the LINQ query with compound from is the simpler one.

Resizing the Main Window of WPF Applications

If the main Window of an WPF application should automatically be sized to its content, setting the Width and Height properties to Auto does not help. With this setting the Window gets a default height and width. To resize the main window to its content, the property SizeToContent can be set. If the Height and Width properties are set as well to Auto, the Window gets resized dynamically as the size of the content changes.

<Window x:Class="SizingTest.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Width="Auto" Height="Auto" SizeToContent="WidthAndHeight" >
  <Grid>
    <Grid.ColumnDefinitions>
      <ColumnDefinition Width="Auto" />
      <ColumnDefinition Width="*" />
    </Grid.ColumnDefinitions>
    <Grid.RowDefinitions>
      <RowDefinition />
      <RowDefinition />
      <RowDefinition />
    </Grid.RowDefinitions>
    <Label Margin="5" Grid.Column="0" Grid.Row="0">Value 1:</Label>
    <Label Margin="5" Grid.Column="0" Grid.Row="1">Value 2:</Label>
    <Label Margin="5" Grid.Column="0" Grid.Row="2">Value 3:</Label>
    <TextBox Margin="5" Grid.Column="1" Grid.Row="0" MinWidth="100" />
    <TextBox Margin="5" Grid.Column="1" Grid.Row="1" MinWidth="100" />
    <TextBox Margin="5" Grid.Column="1" Grid.Row="2" MinWidth="100" />
  </Grid>
</Window>

SWF to XAML

From time to time I'm asked if there's a SWF to XAML conversion tool. From Tim Sneath's blog: The Converted.
It convert's Flash animations to the XAML format.

LINQ to XSD

Scott Hanselman likes the VB 9 support of integrating XML in the language. That's why he found a way to create mixed language assemblies.
Another option to get strongly typed XML support to C# is by using LINQ to XSD. Using this is there still an advantage with the VB9 syntax?

200 Years Wiley

This year, Wiley celebrates 200 years. Wiley is the publisher of my books Professional C# 2005 with .NET 3.0 and Beginning Visual C# 2005.
With some books it's still interesting to read them after 200 years. The earliest surviving book from Wiley is from the year 1812, from William Ballantine. The books I've written have a sligthtly shorter shelf life given the rapid pace of technology! That's why I'm already working on the next editions:

Professional C# 2008
Beginning Visual C# 2008
