Introduction In the first article of the series we discussed how to exchange messages with an orchestration via a two-way WCF Receive Location using the Duplex Message Exchange Pattern . This form of bi-directional communication is characterized by the...

This blog reviews the current (January 2011) set of optio ns available for hosting existing .NET4 Workflow (WF) programs in Windows Azure and also provides a roadmap to the upcoming features that will further enhance support for hosting and monitoring...

This blog post is for those folks comfortable with creating a data stream from an IEnumerable, IObservable or StreamInsight adapter data source.  If you’d like more details on creating those, have a look at this blog post , which covers creating...

Following on the heels of my last query pattern blog post, I started to dig into creating a custom data context for use with StreamInsight and LINQPad.  The default contexts supplied out of box with the StreamInsight driver (including the Hitchhiker...

I’ve always enjoyed building systems that utilized flexible messaging platforms. Before joining Microsoft, I was a member of a small ISV team that built a commercial .NET based ESB product (a rare creature in and of itself) that was primarily a...

This blog entry is a sequel to the October 30th Blog “ Securing WCF Services hosted in Windows Server AppFabric with Windows Identity Foundation (WIF) ” where we demonstrated how to use WIF to secure Services hosted in AppFabric. And in this...

  The following is a good place to get started with how to go about collecting basic information for monitoring and/or troubleshooting an App Fabric (AF) cache setup (Host/Cluster and clients). It starts by pointing to some resources on the different...

Process data, commonly accessed from OPC or a process historian such as OSIsoft PI, is well suited for analysis using StreamInsight – being time-series data with data values from a range of sensors. In this post, I’ll walk through a couple...

A number of customers are choosing to use Entity Framework with Microsoft SQL Azure , and rightfully so. Entity Framework provides an abstraction above the database so that queries are developed using the business model or conceptual model and queries...

Even though this topic looks obvious, there have been some interesting customer scenarios centered around this topic. I am hoping that this blog helps for decision making. As a basic tenet, in most solutions, a distributed cache will be used along with...

A couple of weeks ago I was working with a customer who engaged me to assist with a "little" problem they had – under certain conditions, the system would lose messages coming from a MSMQ queue and designed to correlate to instances of a long-running...

The LINQPad driver for StreamInsight provides an awesomely easy way to run StreamInsight queries using easily accessible data contexts of temporal streams. However, as LINQPad only supports a single active data context connection in a query it can be...

Occasionally, when working with StreamInsight queries an unusual result will crop up, leading to asking the rather blunt question “where did that come from?”. Luckily the StreamInsight Event Flow Debugger has a great feature ( Root Cause Analysis...

At this year’s SQL PASS summit , I had the opportunity to talk with customers about App Fabric Cache and in preparation for the event, I put a demo to show some of the characteristics of the available APIs. The following is an explanation on how...

Abstract (updated version) Technical and commercial forces are causing Enterprise Architects to evaluate moving established on-premises applications into the cloud – the Microsoft Windows Azure Platform. This blog post will demonstrate that there are...

The distinguished field is used to expose the value of a node of a message instance to BizTalk Server system. However, if there is a record that has a parent node that has multiple instances, then that record won’t be able to be highlighted as distinguished...

Introduction One of the important reasons to move an application to the cloud is scalability (outside of other benefits that the cloud provides). When the application is deployed to the cloud, it is critical to maintain performance - the system needs...

Been tied up with PASS for the past (pun intended) couple of weeks, so it’s time to get a bit caught up on writing.  One of the key technical features of StreamInsight is the ability for one query to consume the output of another, enabling the system...

Introduction Some time ago, I was asked by a customer whether or not BizTalk WCF Adapters support the Duplex Message Exchange Pattern. The latter is characterized by the ability of both the service and the client to send messages to each other independently...

Doing a search online for WCF and Cache will eventually lead you to a number of links* demonstrating the use of an IOperationInvoker implementation to manage caching. With AppFabric Cache rapidly becoming a mainstream enterprise technology I felt this...
