C# modeling tools help you model, visualize, analyze, understand and document C# source code.  Most modeling tools use the Unified Modeling Language (UML), which is a standardized way to create visual models from object-oriented source code.

Following is a list of modeling tools that run on Microsoft Windows and model software written with the C# programming language.  Prices listed are direct from the manufacturer for a single license of the “Professional Version” which includes C# round-trip engineering.  This means the modeling tool can read C# source code and generate models, allow the user to make changes to the model, then automatically generate the updated C# code.  Foreign prices are converted to U.S. Dollars at the current exchange rate. 

Please comment with any corrections or additions, as I will keep this list updated.

Wow, I nearly fell out of my chair when I read this little gem on TechCrunch:

Android chief Andy Rubin wrote in a 2005 email, “If Sun doesn’t want to work with us, we have two options: 1) Abandon our work and adopt MSFT CLR VM and C# language – or – 2) Do Java anyway and defend our decision, perhaps making enemies along the way.”

Imagine how different the world would be today if Google had chosen .NET instead of Java as the native development framework for the Android mobile operating system…

An enumerator enables you to iterate over a collection in a foreach loop.  You can use foreach to iterate over all C# collection classes, because all C# collection classes inherit from the IEnumerable interface (regular or generic).  IEnumerable contains the GetEnumerator method, which returns an enumerator.

Occasionally you may find a need to create a custom enumerator, which used to be somewhat of a challenge until the yield keyword was introduced.  Here is how Microsoft describes yield:

The yield keyword signals to the compiler that the method in which it appears is an iterator block.  The compiler generates a class to implement the behavior that is expressed in the iterator block.  In the iterator block, the yield keyword is used together with the return keyword to provide a value to the enumerator object.  This is the value that is returned, for example, in each loop of a foreach statement.

So rather than creating your own enumerator class and managing the enumeration state — which is time consuming and tricky — you can simply write the enumeration logic in the GetEnumerator method, and the yield keyword will automagically wrap your code in a handy-dandy enumerator.

I jump into the controversy about the future of the .NET Framework and HTML5+JavaScript.

Read “.NET Isn’t Dead” on DevTopics.com >>

YourLanguageSucks is a wiki on theory.org that lists reasons why the most popular programming languages suck.  There are long lists of reasons why Java, JavaScript, C++ and PHP suck.  But the list for C# is very short:

• Supports ‘goto’.
• Two distinct sets of collections: non-generic and generic.  Stack and Queue have the same name in both their generic and non-generic flavors, but then we have Hashtable (non-generic) and Dictionary (generic).

The first reason is easy to discount: just avoid using goto!  The second reason is valid, but not really an issue if you use only generic collections, as I do.

When building a C# interface, you may find a need for both public and internal methods, such as:

public class MyClass : IMyInterface
{
    public void MyPublicMethod() { }
    internal void MyInternalMethod() { }
}
public interface IMyInterface
{
    public void MyPublicMethod();
    internal void MyInternalMethod();
}

There is No PaddingF

There is Point and PointF, Size and SizeF, Rectangle and RectangleF, Padding and… wait, there is no PaddingF!

System.Drawing vs. System.Windows.Forms

The 2-D drawing functions in the System.Drawing namespace accept both integer and floating point measurements.  That’s why the main 2-D drawing structures have both int and float versions such as Point and PointF, respectively.

However, the Padding structure is defined separately in the System.Windows.Forms namespace where most 2-D measurements are in integers.  Hence, there is an integer Padding structure but no floating point PaddingF.
