Prism – Composite Application Guidance for WPF and Silverlight – October 2009

This minor update of the Composite Application Guidance for WPF and Silverlight allows you to use the Composite Application Library with Silverlight 3. The following changes were implemented in this release:

  • All Visual Studio projects (Composite Application Library, reference implementation, and Quickstarts) were migrated to use Silverlight 3. If you do not want to upgrade to Silverlight 3, see Opening Projects with Silverlight 2.
  • TabRegionControlAdapter was modified to support binding in the TabItem‘s control header in Silverlight 3. This feature was present for Silverlight 2 but stopped working in Silverlight 3 due to a breaking change. It now supports both versions of Silverlight.
  • Implemented the WeakEvent Pattern for the DelegateCommand‘s and CompositeComand‘s CanExecuteChanged event to fix a possible memory leak in the applications using the Composite Application Library commands. For more information, see Composite Application Library Command Memory Issues and Solution.
  • CreateXap.bat file was modified to search for Silverlight 3 assemblies if the Silverlight 2 reference assemblies cannot be found. This is to support the infrastructure required to run the Composite Application Library unit tests. Applications already using the library will not be affected

MVC or Web Forms? A Dying Question

 

Everyone who talks about ASP.NET MVC gets asked the question:

    Should I use MVC or Web Forms?

There’s been quite a bit of debate on this topic, but in a couple years I don’t think it will matter.

and the stories continues here MVC or Web Forms? A Dying Question until …

The question in the next decade won’t be: “MVC or Web Forms?”.

The question will be: “MVC or SharePoint?

But nobody will ask the question, because the answer is easier to figure out.

31 Days of Refactoring

 

Refactoring is an integral part of continually improving your code while it moves forward through time. Without refactoring you accrue technical debt, forget what portions of code do and create code that is resistant to any form of testing. It is an easy concept to get started with and opens the door to much better practices such as unit testing, shared code ownership and more reliable, bug-free code in general.

Day 1 : Encapsulate Collection

Day 2 : Move Method

Day 3 : Pull Up Method

Day 4 : Push Down Method

Day 5 : Pull Up Field

Day 6 : Push Down Field

Day 7 : Rename (method, class, parameter)

Day 8 : Replace Inheritance with Delegation

Day 9 : Extract Interface

Day 10 : Extract Method

Day 11 : Switch to Strategy

Day 12 : Break Dependencies

Day 13 : Extract Method Object

Day 14 : Break Responsibilities

Day 15 : Remove Duplication

Day 16 : Encapsulate Conditional

Day 17 : Extract Superclass

Day 18 : Replace exception with conditional

Day 19 : Extract Factory Class

Day 20 : Extract Subclass

Day 21 : Collapse Hierarchy

Day 22 : Break Method

Day 23 : Introduce Parameter Object

Day 24 : Remove Arrowhead Antipattern

Day 25 : Introduce Design By Contract Checks

Day 26 : Remove Double Negative

Day 27 : Remove God Classes

Day 28 : Rename boolean methods

Day 29 : Remove Middle Man

Day 30 : Return ASAP

Day 31 : Replace Conditional with Polymorphism

Running IronPython Scripts from a C# 4.0 Program

 

Running IronPython Scripts from a C# 4.0 Program

Before you read this you may want to check out my other post.

IronPython is a scripting language hosted on the .NET platform. This posts shows how you can use the Dynamic Language Runtime (DLR) and the new C# 4.0 dynamic keyword to call an IronPython script from a C# program.

Test.py

import sys

def Simple():
    print "Hello from Python"
    print "Call Dir(): "
    print dir()
    print "Print the Path: " 
    print sys.path

 

using System;
using IronPython.Hosting;
using Microsoft.Scripting.Hosting;

public class dynamic_demo
{
    static void Main()
    {
        var ipy = Python.CreateRuntime();
        dynamic test = ipy.UseFile("Test.py");
        test.Simple();
    }
}
