Web services Contract-First

thinktecture has written a Visual Studio .NET Add-In and Command Line Tool for Improved “Contract-First” Web services Design and Programming.

thinktecture’s Christian Weyer: “There has been a lot of buzz around contract-first Web services design & development lately. Nearly everybody thinks that it is a good thing, and that we finally should reach a state where we all can live and breath it. But most people have been complaining about the lack of tool support for the so called ‘first step’:

  • Design your contract’s messages and interface
  • Generate code from the contract

Our tool has been quite good at the last one of the two points: code generation. But there always was a missing link to how to design and model the contract effectively.

Now we from thinktecture are proud to present the next version of our very successful and freely available WSCF (formerly known as WsContractFirst). This new version 0.4 now offers a simple yet powerful WSDL Wizard that abstracts away all the nitty-gritty details of WSDL and therefore does not give room for making errors and wrong assumptions just by trying to use and applying everything that can be done stated by the original WSDL specification.”

2.7 grams, and it’s a helicopter

The Nanoflyer is the smalest RC helicopter in the world:

Weight of components:

  • Motors(2) 0.8 grams*
  • Electronics 0.1 grams
  • Battery 0.7 grams
  • Airframe 1.1 grams

See it fly: Medium quality Nanoflyer video 1:13 (2.0Mb)

Want one for Christmas (I do!!)? You’ll have to settle for the slightly larger (50 grams) Bladerunner. It is the first commercial product to utilize the Proxflyer principle.

* 1 gram = 0.035273962 ounce(US) / 0.032150747 (Troy)

Neo (.NET Entity Objects)

Why Neo? Because it is simple and object-oriented:

The following code snipped shows how to load all titles (i.e. books) that were published before a certain date, apply a clearance discount and then save the changes to the database:

IDataStore datastore = new SqlDataStore(" database connection string ");
ObjectContext context = new ObjectContext(datastore);
TitleFactory factory = new TitleFactory(context);
TitleList matchingTitles = factory.Find("PublicationDate < {0}", new DateTime(2003, 1, 1));
foreach(Title title in matchingTitles) {
    title.ApplyClearanceDiscount();
}
context.SaveChanges();

Where ApplyClearanceDiscount() could look like:

public void ApplyClearanceDiscount()
{
    this.Price = this.Price * (1 - GetClearanceDiscount());
}
