Microsoft Windows Communication Foundation (WCF) 3.5 Microsoft .NET Framework 3.5 Microsoft Visual Studio 2008 This how-to article shows you how to perform message validation using a schema in WCF.
You will learn how to create a custom client message inspector and dispatcher message inspector that can be used to validate messages on both the server and the client. Learn how to create a custom configuration element that will allow exposing the custom endpoint behavior in the configuration file. Learn how to create a custom endpoint behavior that will consume the client and dispatcher message inspectors. Free download - Presentations. LikeMind. Excellence. Professional Growth. Leadership. The IDesign serviceware downloads is a set of original techniques, tools, utilities and even breakthroughs developed by the IDesign architects.
The utilities are largely productivity-enhancing tools, or they compensate for some oversight in the design of .NET or WCF. The demos are also used during our Master Classes to demystify technical points, as lab exercises or to answer questions. The classes' attendees find the demos useful not only in class but after it. The demos serve as a starting point for new projects, and as a rich reference and samples source. Understanding Performance Profiling Targets. In this sample chapter from his upcoming book (co-authored with Chris Farrell), Paul Glavich explains performance metrics and walks us through the steps needed to establish meaningful performance targets.
He covers many metrics such as "time to first byte" and explains why you should add some contingency into your estimated performance requirements. Naturally, in order to achieve a goal, you first need to understand what that goal is. So, before you can determine whether your application performs well, you need to understand that means in terms of the metrics your application needs to produce. Whether or not your application performs well is a relative target; not all applications are the same. My Advice for .NET Application Architecture and Design. This post summarizes my general architecture and design guidelines for developing applications and points to some interesting NET technologies.
Reading this post will not make anyone an architect, but working through it should give you a good foundation for understanding and discussing architecture and design decisions. BTW: Architects must write code to really understand what they are talking about and experience some of the pain their design decisions may cause for project managers, programmers, DBAs, operators and users (see MS WeSYP). Table of contents: Developing Modifications that Survive Concurrency. You can create a database under the assumption that SQL looks after all the problems of concurrency.
It will probably work fine under test conditions: Then, in the production environment, it starts losing data in subtle ways that defy repetition. It is every Database Developer's nightmare. UML Interview Questions Part 1. Table of Contents Introduction Again i repeat do not think you get an architecture position by reading interview questions.
But yes there should be some kind of reference which will help you quickly revise what are the definition. Just by reading these answers you get to a position where you are aware of the fundamentals. DB Concurrency Control with .NET – Overview. This (long) posting provides guidelines for using common patterns to control concurrency when using relational databases (RDBMS) via ADO.NET or the .NET Entity Framework (EF).
MS SQL Server and Oracle are used as examples to sensitize you for the implications of RDBMS specific concurrency model implementations. When multiple sessions (users, processes) attempt to concurrently modify database data, modifications by one session can adversely affect modifications by simultaneous sessions or cause inconsistencies in the database(s). Some of the most common problems are: Lost updatesInconsistent queriesBad response timesInsufficient scalabilityDeadlocksTimeouts. Execution Plan Basics. We are very pleased to be allowed to publish the first chapter from Grant Fritchey's excellent new book, Dissecting SQL Server Execution Plans.
You can download it for free here. Grant's book is also currently available in several eBook formats:PDF format from Lulu.comMobipocket formatKindle format from Amazon.com ... and you can inspect an HTML version of the Table of contents here... Graphical Execution Plans for Simple SQL Queries. Learning how to read and analyze execution plans takes time and effort.
But once you gain some experience, you will find them an essential skill for getting to grips with performance issues in SQL Server Queries. Grant here describes the range of execution plans for different simple SQL Queries. This is the second chapter from Grant Fritchey's excellent book, Dissecting SQL Server Execution Plans.You can download it for free here. Grant's book is also currently available in several eBook formats: PDF format from Lulu.com Mobipocket format Kindle format from Amazon.com ... and you can inspect an HTML version of the Table of contents here... The aim of this article is to enable you to interpret basic graphical execution plans, in other words, execution plans for simple SELECT, UPDATE, INSERT or DELETE queries, with only a few joins and no advanced functions or hints. The Language of Graphical Execution Plans In the previous article, we only saw two operators (Select and Table Scan ).

Heap (data structure) Example of a complete binary max-heap with node keys being integers from 1 to 100 1. the min-heap property: the value of each node is greater than or equal to the value of its parent, with the minimum-value element at the root. 2. the max-heap property: the value of each node is less than or equal to the value of its parent, with the maximum-value element at the root.
Throughout this article the word heap will always refer to a min-heap. In a heap the highest (or lowest) priority element is always stored at the root, hence the name heap. WCF and MSMQ - Dennis van der Stelt. It’s been a while since I blogged about one of my favorite topics, Windows Communication Foundation. In this article I’ll explain how you can use MSMQ with WCF to really process messages asynchronously. It’s unbelievable how easy this is. Read my complete WCF series on how to set up your first service. The idea in this example is that we have to send some e-mails, but we don’t want that to be done immediately.
We’ll setup the service with a Console Application. WCF configuration default limits, concurrency and scalability - Paolo Pialorsi - Bridge The Gap! Often I need to enumerate to my customers all the main configuration parameters related to default limits, concurrency and scalability of WCF, thus I decided to keep truck of all those parameters and features in order to have a unique place for reference. From a configuration point of view, WCF provides some parameters that influence the availability and scalability of solutions. These parameters are: configuration/system.serviceModel/behaviors/serviceBehaviors/behavior/serviceThrottling/@maxConcurrentCalls: defines the maximum number of messages actively processed by all the service instances of a ServiceHost. The default value is 16. Calls in excess of the limit are queued.
These configuration parameters can also be configured by code using the ServiceThrottlingBehavior configuration. Another set of interesting configuration parameters are those related to the default limits of messages, serialization measures, etc. of the various bindings. Enabling SSL for a WCF Service.

The Secure Sockets Layer security protocol explained. The Secure Socket Layer (SSL) and Transport Layer Security (TLS) is the most widely deployed security protocol used today.
It is essentially a protocol that provides a secure channel between two machines operating over the Internet or an internal network. In today’s Internet focused world, the SSL protocol is typically used when a web browser needs to securely connect to a web server over the inherently insecure Internet. Technically, SSL is a transparent protocol which requires little interaction from the end user when establishing a secure session. Accessing WCF service without creating Proxy - Debug Mode.
