Workflow and Host Communication in WF 4.0–Bookmarks(sankarsan.wordpress.com)

submitted by sankarsan(460) 1 month, 5 days ago

In the last post we have discussed at length about different mechanisms of parameter passing and obtaining results from a workflow.In this post we will discuss about another extremely important aspect of workflow and host communication i.e. Bookmarks. Bookmarks as the name suggests is a like Bookmark for a book. When created at a particular point in the execution of the workflow , the execution is suspended and the workflow waits to be resumed.When a bookmark is resumed it starts executing exactly from the same point. read more...

Workflow and Host Communication in WF 4.0–Parameter Passing(sankarsan.wordpress.com)

submitted by sankarsan(460) 1 month, 19 days ago

Workflow host is an application responsible for executing the workflow and managing different workflow lifecycle events like start, completion, idle, unloaded etc.Now the workflow host should be capable of exchanging information with the workflow. This information exchange can be broadly categorized into: a) The parameters/arguments needed to start the workflow and to get the results back after workflow has executed. b) The intermediate data needs at different stages of a long running workflow (e.g. when the workflow is waiting for a specific input like Manager’s Approval). In this post we will concentrate on the different mechanisms of parameter passing and getting results back. In the subsequent posts we will move into more complex scenarios related to long running workflows. read more...

ASP.NET Web API–Http Messaging(sankarsan.wordpress.com)

submitted by sankarsan(460) 2 months, 23 days ago

ASP.NET MVC 4 (right now in Beta) has introduced the ASP.NET Web API , a MVC compliant framework for developing and hosting HTTP services which can be accessed from a variety of clients.In this post we will take how the ASP.NET Web API request processing pipeline works and HTTP request is passed between different processing stages. ASP.NET Web API can be hosted in IIS like a normal ASP.NET Web application and it can be also self hosted within a simple console application.For the sake of simplicity we will use a self hosted application here. read more...

Inside ASP.NET 4.5 Bundling and Minification(sankarsan.wordpress.com)

submitted by sankarsan(460) 6 months ago

ASP.NET 4.5 has introduced built-in support for bundling and minification of javascript and css resources.Here minification refers to the mechanism of compressing the javascript & stylesheet files thus reducing the size of data to transferred over the wire. The process of bundling involves combining multiple javascript/css files into one, thus reducing the number of HTTP calls made from the browser. The following post by Abhijit Jana gives a nice illustration of the feature covering the basics and the advanced areas as well. http://abhijitjana.net/2011/10/06/bundling-and-minification-in-asp-net-4-5/ read more...

Roslyn CTP–Syntax Tree–Part II–Singleton Checker(sankarsan.wordpress.com)

submitted by sankarsan(460) 6 months, 7 days ago

In the last post related to Roslyn we developed a very basic syntax walker. In this post we will see how we can use the same for code analysis and checking. As a good practice we generally try to avoid having instance members in a singleton class. This is true if you are making your business logic layer classes Singleton and would prefer to avoid mess up by multiple threads.... read more...

Let’s consider a situation where we have a data source which is churning out data like a continuous stream and passing it to some data processing units (like a method) as shown in the figure below.The processing units are load balanced i.e. if one unit is still busy processing then the next element coming out of the data source will be handed over to the next processing unit. read more...

In one of my earlier posts about the Parallel Programming Extensions in .NET 4.0 I had briefly mentioned about the Task Parallel Library one of the most critical components of the Parallel Extensions.It primarily consists of the APIs provided under System.Threading& Sytem.Threading.Tasks.It uses the CLR Thread Pool behind the scenes and some sophisticated algorithms to assign number of threads to maximize performance.It provides more programmatic control than thread or work item to... read more...
