Enterprise Library: Take Exception To Critical Errors With Custom Application Blocks


Enterprise Library is a collection of application functionality blocks that you can re-use in your application for common functionality you'd otherwise have to write again and again. Here Jay Hilyard explains how to use them.

Application Blocks & Enterprise Library


Is there a difference between Microsoft's Application Blocks and Microsoft's Enterprise Library?  I am a complete nubie with a little classroom training and some success with writing and launching a website.

My site barely works.  I need to trash my website and start over using some sort of best practices.  Does anyone have suggestions?  Will Application Blocks help?  How about the EntLib?

Data Points: The Enterprise Library Data Access Application Block, Part 3


E nterprise applications can have a wide variety of data update requirements. Sometimes you need to save multiple rows of changes at once within a single transaction. Other times, the user must be allowed to enter multiple rows of data, send them to the database in a batch; and if a row or two fails, only the rows that succeeded should be committed and remain committed.

Data Points: The Enterprise Library Data Access Application Block, Part 2


Last month I explored the foundation of the Enterprise Library Data Access Application Block (DAAB) including how it all fits into an architecture (see Data Points: The Enterprise Library Data Access Application Block, Part 1).

A solid data access later (DAL) can benefit an application by hiding redundant tasks, helping handle exceptions more gracefully, helping clean up resources more efficiently, and providing a layer of abstraction from the database.

Book review: Patterns of Enterprise Application Architecture

   Lately I finished reading the famous patterns book by Martin Fowler - Patterns of Enterprise Application Architecture. This book introduces and describes design patterns you will usually see when building enterprise applications. There are also examples for patterns and although they are simple and primitive they give you the idea how to implement or use specific patterns. If you are working on enterprise applications every day you will find this book very useful and I'm sure you will use it as manual. Yes, you can read this book as any other book and you can also use it as manual. In the end of this review you can find table of patterns with links to short introduction for each pattern. Are these patterns platform specific somehow? No, they are not. It doesn't matter what platform or language you are using. Of course, you must know your platform well because some of problems solved in this book maybe also already solved on platform you are working on. Don't try to push all available patterns to your application - use patterns of this book when you face problems that your tools doesn't solve or that your tools solve poorly. Of course, you can consult with this book if you are not sure how to implement one or another pattern in your application. My suggestion is to read this book with two other books (of course, there are more recommended books but le

Question on Microsoft Enterprise Library 5.0 for a mobile web application



Our company is in the process of building a new website dedicated for mobile devices.

Since we are starting from scratch, I would like to consider implementing the Microsoft Patterns & Practices Enterprise Library 5.0 on the site.

I would like to ask others what they think

1) Is this too much overhead where speed is mission critical?

2) Have you implemented this library for a mobile site? If so, why? Please describe your experience.

3) Given time and resources, would you implement this library?

I appreciate all feedback



Microsoft Enterprise Library 5.0 - Logging Application Block Activation Error


Hi folks,

I've been writing a class where I wanted to write the errors off to the OS EventLog. I was pointed towards the Logging Application Block. I used LogWriter successfully in a web page and transfer the code to the class so that I could have the functionality there.

I keep getting an {"Activation error occured while trying to get instance of type LogWriter, key \"\""} Error when I reach this line of code:

private LogWriter writer = EnterpriseLibraryContainer.Current.GetInstance<LogWriter>();

I had something similar with the daab getinstance call but I added the unity assemblies to the code and this resolved this. I thought this was the issue with this problem.

Could anyone tell me what I'm doing wrong?

Thanks in advance folks.

app.config code:


<?xml version="1.0" encoding="utf-8" ?>
        <section name="loggingConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.LoggingSettings, Microsoft.Practices.EnterpriseLibrary.Logging, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="true" />

Scale Up Enterprise Library Caching Application Block


CAB from MS is a very famous tool for the developers as it saves a lot of valuable time of the developers. But anyone who has decided to use CAB, should also keep into mind its limitations as well. The cache in EnltLib is stand alone and in-process in nature that’s why it can ends up with some scalability and reliability issues when used in a multi-server environment. But there are some party integrations which can over come this issue. The most popular way to overcome these limitations of CAB is the use of a distributed cache. The article about the drawbacks of CAB and it solutions can be a very helpful read in this regard. 

High-Performance .NET Application Development & Architecture

It has always been a goal of project architects to plan an effective strategy from the ground up in regards to an new application. All relevant factors are taken into consideration with respect to the application, from its design and layout to a functional website infrastructure. Pre-.NET strategies and design guidelines still effective now were developed with Microsoft's DNA (Distributed interNet Application) platform. This model successfully served the purpose of architecting N(any number of)-Tier (levels) applications. In its basic sense, as in most robust, distributed applications, you'll architect 3 main layers or Tiers: presentation, business rules and data access.

Logic behind N -Tier Application Development

In the arena of application development, developers all over the world use various programming languages, technical processes, and technical tools. While using number of technical & non technical elements the processes or methods become complex, for simplification of the application development process, developers use various techniques such as dividing the application architecture into layers or parts. In the professional & technical language this separation or division process is called N-Tier Application Development process, where "N" stands for number and "tire" stands for layers or parts.

Solidify Your C# Application Architecture with Design Patterns

design pattern can solve many problems by providing a framework for building an application. Design patterns, which make the design process cleaner and more efficient, are especially well-suited for use in C# development because it is an object-oriented language. Existing design patterns make good templates for your objects, allowing you to build software faster. This article describes several popular design patterns you can use in your own applications, including the singleton, the decorator, the composite, and the state classes, which can improve the extensibility of your applications and the reuse of your objects.

MVC + Frames in an enterprise web application


Hi people

I'm designing an enterprise web application interface based on an old system, and i planned to migrate the old frames layout to master page, but i noticed that if i use masterpages, the application users will be able to see the querystring or route path, and it could be a security issue.

What is the best way to avoid this? Using frames? Masterpages with iframes as content? Masterpages with all PartialViews loaded by jquery?




How to set up microsoft application blocks 4.0 to talk to event viewer


I need to set up the microsoft application blocks 4.0 on the server and connect it to my web project.  I need to set it up so that all the errors are logged in the event viewer.  So far I have found out how to set up a flat file listener and send the error to a log file but, not to the event viewer.  Any suggestions would be helpful.

    Application Blocks


    What are microsoft application blocks and how to use them ? 

    MVC + Enterprise Library


    Not a MVC specific question, but as that's what I'm doing I thought I'll post here.

    While looking into the source code of an existing application, I stumbled upon MS Enterprise Library, and as I only heard about these "application block" stuff decided to look into it.

    From the theory it sounds like a pretty usefull thing and it made me wonder if other's are using it succesfully along with MVC projects (I know they are not really related!)?

    Pro's and Con's? 

    I like the database block, as I did not get to any real database development the last 1.5 years, for instance. (Bad excuse I know).  Having an IoC thrown in there (Unity) sounds like I can pretty much stop using 3rd party libraries like I do now all over the place.

    Using the ConsoleTraceListener with the Enterprise Library 3.1 Logging Block


    I'm new to using the Logging application block.  I think I have a pretty good handle on how things work.  However, I'm running into a problem.  I'm using the RollingFlatFileListener and I have formatted the logging template to be more like the logging we are replacing.  However, in our console apps when the ConsoleTraceListener is added it still logs it out in the default text template format.  Is there any way to get around this?  Currently it looks like I will have to create a new TraceListener called FormattedConsoleListener that allows a text formatter to be associated with it.  Is this the only way?
