  • Instrumenting Applications with .NET Tracing

    Last updated: Tuesday, February 19, 2019

    Published in: CODE Magazine: 2004 - September/October

    Application instrumentation gives you the ability to perform runtime diagnosis of enterprise application state, which is critical to mission success.To help with instrumentation and logging, .NET ships with tracing types in the System.Diagnostics namespace. Using these types, you have the ability to log information to multiple output streams for diagnosis of application runtime behavior. Information produced by instrumentation and tracing types enable you to examine the runtime state of an application and fix problems that would be otherwise expensive and painful to solve.

  • Managing .NET Code Access Security (CAS) Policy

    Last updated: Wednesday, August 31, 2022

    Published in: CODE Magazine: 2004 - May/June

    Code Access Security (CAS) is the .NET Common Language Runtime (CLR) mechanism for maintaining security based on the identity of code.Most developers don't have to work with CAS on a daily basis because the .NET Framework libraries take care of much of the work involved in securing code. However, when you do need to work with CAS, having a good understanding of CAS policy management is essential. Waiting until the eleventh hour in the project lifecycle and realizing that you need to configure security policy is painful. For example, if you have a Smart Client application that runs over Internet Explorer, you will need to consider what permissions your application requires and how you are going to configure policy so that your code will run on a client machine. Or, suppose that your application defined a custom permission for a scenario not already covered by the permissions that ship with .NET. Here again you need to understand CAS policy. This article discusses the essential elements of CAS (evidence, permissions, and policy), shows how .NET CAS policy works, and explains reasons for making various policy decisions.

  • RIA Services: RAD for the Middle Tier

    Last updated: Wednesday, August 31, 2022

    Published in: CODE Magazine: 2009 - July/August

    RIA Services is a new Microsoft framework for developing n-tier Line of Business (LoB) applications. RIA Services make it easier to build Silverlight applications that communicate with a server, which is the focus of this article. As a developer, RIA Services provides automatic code generation for common scenarios where you need to perform CRUD operations on data and have a consistent model to validate data across tiers. The following sections explain how to get started with RIA Services, specify a data source and a UI, and automatically generate code for CRUD operations. Let me show you the big picture of RIA Services from an architectural perspective first.
