From LINQ to SilverLight – Watch videos and hear about all the cool technologies coming and the people behind them. http://channel9.msdn.com/Niners/melnik/Posts en Mon, 20 May 2013 14:33:57 GMT Mon, 20 May 2013 14:33:57 GMT Rev9 8 1 25 Introducing Semantic Logging Meet the new application block from Microsoft patterns & practices team - the Semantic Logging Application Block. It is intended to help you move from the traditional, unstructured logging approach (such as that offered by the Logging Application Block or log4net) towards the semantic logging approach that improves the consistency of the logs and simplifies significantly their consumption and automatic processing.

The Semantic Logging Application Block enables you to use the EventSource class and semantic log messages in your applications without moving away from the log formats you are familiar with (flat files, databases, Windows Azure table storage etc). Importantly, you do not need to commit to how you consume events when developing business logic; you have a unified application-specific API for logging and then you can decide later whether you want those events to go to ETW or alternative destinations.

In this tutorial, we demonstrate the Semantic Logging Application Block in action. We also showcase the out-of-proc service to help reduce the logging overhead in your applications and improve fault tolerance of the logging process.

If you rely on manual interventions to scale your application, you may not always achieve the optimal balance between costs and performance. An autoscaling solution reduces the amount of manual work involved in scaling an application dynamically.  In this video, we demo how this can be accomplished with WASABi (the Windows Azure Application Block) in two different ways: either by preemptively adjusting the number of role instances based on a timetable, or reactively by adjusting the number of role instances in response to some metric that you can collect from your application or Windows Azure environment.

The first WASABi preview is available via NuGet (just search for 'wasabi' from the NuGet Package Manager within Microsoft Visual Studio).

We provide an overview of WASABi scenarios and the block's architecture. If you want to jump straight to the demo, skip to 15:43.

Now it can be used in Silverlight applications.

The centralized exception management functionality is configured as a set of poicies that can be defined in an external configuiration file or programmtically.

We are using the StockTrader V2 Reference Implementation to show how the Exception Handling Application Block addresses various Silverlight-specific scenarios, including how to apply exception handling to asynchronous services.

Download the Silverlight Integration Pack or get the Exception Handling Application Block automatically added to your Silverlight project via NuGet.

However, it was not available on Silverlight. Until now.

In this demo, we discuss interception as a code modularization technique for dealing with cross-cutting concerns.  We contrast 2 types of interception - instance and type interception.

Using the newly implemented interception support provided by the Silverlight Integration Pack, we show a virtual method interceptor in action (which can intercept any methods declared virtual on your type).  We also show the nuts and bolts of implementing custom interception behaviors and chaining them into a pipeline (similar to the Chain-of-Responsibility design pattern).

Though the demo targets Silverlight, it can also be helpful for those learning how to take advantage of Unity Interception in their desktop CLR apps.
