.NET4 Hosting :: .NET 4 Feature Focus - Code Contracts

clock November 17, 2009 07:34 by author Administrator

There are many new exciting things that we can find on the latest .NET4 Framework and one of them is the ability to use the “Code Contracts”. ASPHostCentral.com as a premier Windows and .NET Hosting provider, proudly announces that this latest framework has been supported on our entire new servers environment. You can start hosting your .NET4 Beta 2 website from just paying as low as $4.99/month with FREE 1 domain and 1 SQL 2005/2008

Design by contract builds on top of concepts like static typing, where certain actions cannot be performed unless it can be verified at compile time. Contracts usually take the form of pre- and post-conditions such as a parameter or return value never being null or only containing a certain range of values.

Rather than force developers to learn a whole new language such as Spec#, Microsoft is working on a language-agnostic library that can be leveraged by any .NET language. In some ways contracts look like assertions, but they are very different under the covers. Contracts are supported by a combination of static code analysis, which can be both inside and outside the compiler, as well as by testing frameworks. They are also executable, meaning they behave like assertions when running a debug build. Consider this first example:

string GetDescription(int x){

Contract.Requires(x>0);

Contract.Ensures(Contract.Result<string>() != null);

Looking at just the signature, developers only get the static type information "GetDescription requires an integer and returns a string". With the contracts, both developers and tools know "GetDescription requires a positive integer and returns a string that is never null".

In addition to explicit contracts, the contract checker can also support implicit contracts. One such example is division by zero. If a class includes a division of integers where the divisor is a variable, then all code paths must ensure that the variable is never zero or a warning is issued. If the variable in question is a property on a unsealed class, this would require checking in every subclass as well. There are also implicit contracts for dereferencing nulls and array indexes.

To make this easier, there is the concept of an ObjectInvariant method. This special method, which only contains contracts, is injected into the end of each method call to ensure the object's state remains consistent. It is important to note that this applies to all methods, including those in subclasses from other assemblies.

Another time saving device is easy access to old values. In this example the Ensures contract is used in conjunction with the OldValue syntax to make certain that the collection's count property is incremented.

Public Sub Add(value as Object)

Contract.Ensure(Count = Contract.OldValue(Count) + 1)

Even though the contract is written at the top of the method, it will automatically be moved to just before the Return statement by the compiler. As there is some overhead for storing the old value of Count, this sort of check will only occur in debug builds.

In order to support library developers, release builds include a reference assembly. For example, the Widgets.dll assembly would have the bulk of its contracts extracted and placed in the assembly Widgets.Contracts.dll. This allows client developers to use the faster release-style builds while still leveraging the contracts created by the library developers.

One of the more interesting features is that contracts do not just apply to concrete functions. Even interface and abstract methods with no other implementation detail can have contracts. This is done by creating a reference implementation of the interface whose sole purpose is to hold contracts. This reference implementation is linked back to the interface by attributes.

There are no restrictions on the contents of a contract. Since the same contracts are used for both static and runtime checking, a complex constraint that cannot be evaluated by one may still be checked by the other. Contracts can also be extracted by documentation generators.

 



.NET4 Hosting :: Overview of Microsoft .NET Framework 4

clock November 2, 2009 05:19 by author Administrator

The Microsoft .NET Framework 4 redistributable package installs the .NET Framework runtime and associated files that are required to run and develop applications to target the .NET Framework 4. This download consists of a new Web-based installer that simplifies the installation process. ASPHostCentral.com as a premier Windows and .NET Hosting provider, proudly announces that this framework has been supported on all our new servers environment. You can start hosting your .NET4 website from just paying as low as $4.99/month with FREE 1 domain and 1 SQL 2005/2008

Overview

The .NET Framework is Microsoft's comprehensive and consistent programming model for building applications that have visually stunning user experiences, seamless and secure communication, and the ability to model a range of applications.

The .NET Framework 4 works side by side with older Framework versions. Applications that are based on earlier versions of the Framework will continue to run on the version targeted by default.

The Microsoft .NET Framework 4 provides the following new features and improvements:

·         Improvements in CLR and BCL

o    Performance improvement including better multicore support, background garbage collection, and profiler attach on server.

o    New memory mapped file and numeric types

o    Easier debugging including dump debugging, Watson minidumps, mixed mode debugging for 64 bit and code contracts.

·         Innovations in the Visual Basic and C# languages, for example statement lambdas, implicit line continuations, dynamic dispatch, and named/optional parameters.

·         Improvements in ADO.NET

o    Entity Framework, which simplifies how developers program against relational databases by raising the level of abstraction. The Entity Framework has many new features in the .NET 4 Framework. These features include persistence ignorance and POCO support, Foreign Key Associations, lazy loading, test-driven development support, functions in model, and new LINQ operators.

o    Data Services framework consists of a combination of patterns and libraries that enable the consumption of REST-based data services for the web. ADO.NET Data Services has many new features in the .NET 4 Framework. These features include: enhanced BLOB support, Data Binding, Row Count, Feed Customization, Projections, and Request Pipeline improvements. Built-in integration in Microsoft Office 2010 now makes it possible to expose Microsoft Office SharePoint Server data as a data service and access that data using the ADO.NET Data Services client library.

·         Enhancements to ASP.NET

o    New JavaScript UI Templates and databinding capabilities for AJAX.

o    New ASP.NET chart control.

·         Improvements in WPF

o    Added support for Windows 7 multi-touch, ribbon controls, and taskbar extensibility features.

o    Added support for Surface 2.0 SDK.

o    New line-of-business controls including charting control, smart edit, data grid, and others that improve the experience for developers who build data centric applications.

o    Improvements in performance and scalability.

o    Visual improvements in text clarity, layout pixel snapping, localization, and interoperability.

·         Improvements to Windows Workflow (WF) that enable developers to better host and interact with workflows. These include an improved activity programming model, an improved designer experience, a new flowchart modeling style, an expanded activity palette, workflow-rules integration, and new message correlation features. The .NET Framework 4 also offers significant performance gains for WF-based workflows.

·         Improvements to Windows Communication Foundation (WCF) such as support for WCF Workflow Services enabling workflow programs with messaging activities, correlation support. Additionally, .NET Framework 4 provides new WCF features such as service discovery, routing service, REST support, diagnostics, and performance.

·         Innovative new parallel-programming features such as parallel loop support, Task Parallel Library (TPL), Parallel LINQ (PLINQ), and coordination data structures which let developers harness the power of multi-core processors
