A key challenge while designing and deploying Web Services is access control and this blog post is the first in a two part series focused on leveraging Windows Identity Foundation (WIF) to secure Services hosted in Windows Server AppFabric. In this first...

Scenario During recent years, I had the chance to work with many customers and I realized that one of the most recurring problems they usually experience is due to long start-up times: indeed, this is not a BizTalk specific issue, it’s rather...

I always have a sense of satisfaction when I find out that there is less tweaking or tuning needed to make my applications perform as expected under high throughput workloads (or that the tweaking is easier to do).  I had this sense of satisfaction...

Event Driven Updates If I can't have magic then I want something easy. I'd like to have changes that occur on certain tables be reflected in AppFabric Cache. I'd also like this to occur in an event based manner. "Use SqlDependency and be done with...

The StreamInsight dev team has just released the next version of StreamInsight (version 1.1)!!  New features in this release include: .NET Sequences - no more custom adapters for common .NET data sources.  Using .NET sequences instead of adapters...

This is a pretty obscure one, and a nice short snippet of a blog post.  I ran into this error yesterday while building out some StreamInsight applications for real time web analytics, and was very briefly stumped.  Let’s have a quick peek at...

The title lends itself to a bit thought.  Why would the developer feel the need hold a static reference to the MetadataWorkspace of an Entity Framework (EF) model from within their WCF service-oriented applications?  The premise being that the...

StreamInsight has a very powerful management service that is fully available to developers and administrators alike. Any technique that you see in the Event Flow Debugger or in the API can be remotely invoked via the Management Service . This enables...

Using reference data in StreamInsight is a very common scenarios; some examples would be: Monitoring process control event streams for values that exceed a given threshold (for example, a valve’s pressure exceeding a certain safety threshold). Enriching...

co-Authored by Thiago Almeida (Datacom) reviewed by Conor Brady (Oakton) Developing a BizTalk Server solution can be challenging, and especially complex for those who are unfamiliar with it. Developing with BizTalk Server, like any software development...

I’ve seen a lot of services routing solutions. Some used expensive hardware. Some were built on top of integration or ESB platforms and others were simply built from the ground up. Building from the ground up has always been the most flexible...

T4 background Leveraging the power of Text Template Transformation Toolkit (T4 template) to generate code (or any other type of text) is a great time saver and it is particularly useful when working with Entity Framework (EF) since it allows to easily...

One of the common tasks in StreamInsight is to use a reference stream to integrate metadata or reference data from a relatively static source (such as a SQL Server table – a walkthrough of this technique will be described in an upcoming blog post). ...
