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 WF service hosted in IIS/AppFabric. The Rule...

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 either using one-way or request/reply messaging...

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 to be an ideal time to revisit this concept. I...

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 blog post we focus on securing both WCF and Workflow...

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 a problem affecting any .NET application, regardless...

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 just this week with some new insights on WCF 4...

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 WCF services are using EF to serve up data from...

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 effort is like playing chess. There are some great...

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 method with the obvious drawback that it was also...

Introduction In the first article of the series, we discussed the advantages and disadvantages of using Dynamic Send Ports in a BizTalk application and in particular within a solution that makes an extensive use of the ESB Toolkit. We also talked about how to create custom services to boost the...

Introduction In the first part of the article we have introduced and analyzed the problem regarding the transmission and reception of a large message via a WCF Receive Location. In particular, we discussed the difference between the Buffered and Streamed transfer modes provided by WCF and in particular...

Introduction This is the first in a series of articles that will introduce and explore a couple a patterns to transfer and process large messages using WCF-Adapters. Generally speaking, an end to end BizTalk solution adopts the FTP Adapter or one of its variations (SFTP/FTPS) when it needs to exchange...

Scenario Last year I wrote a post on how using BizTalk Server 2006 R2/2009 and Protocol Transition to impersonate the original caller when invoking a downstream service that uses the Windows Integrated Security. Recently, one customer posed the following question to my colleague, Tim Wieman: Can...

Introduction In the following post I’ll explain in detail a demo that I presented at TechReady 9 and TechEd 2009 in Berlin. The Problem Consider the following scenario: Your BizTalk application receives an XML request message through a two-way Receive Location (e.g. WCF, SOAP, HTTP...

Introduction The contents of the following post are taken from a presentation I created and delivered at TechReady 9 in July 2009 and replicated with Stephen Kaufman at Tech-Ed Europe 2009 . The ABC of WCF Windows Communication Foundation (WCF) is a runtime and a set of APIs for exchanging messages...

Introduction One of the most common scenarios in BizTalk applications is when an orchestration receives and processes an incoming XML document to produce a result message. Sometimes this latter can be generated just transforming the inbound message with a map, but in another cases the orchestration...
