Question on Microsoft Enterprise Library 5.0 for a mobile web application

Posted By:      Posted Date: September 23, 2010    Points: 0   Category :ASP.Net


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" />

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.

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.

Wireless Web: Microsoft Mobile Internet Toolkit Lets Your Web Application Target Any Device Anywhere


If you've built Web sites using ASP.NET, you'll welcome the Microsoft Mobile Internet Toolkit (MMIT). MMIT extends the Visual Studio .NET IDE you already know by providing new controls for handheld devices letting you easily develop applications for wireless devices. This means you can write less code while adapting it to more devices. Not only does MMIT integrate with Visual Studio .NET, it extends ASP.NET as well. This article gives you the background you need to write, test, and deploy a site with MMIT and make all your code able to target specific devices for a custom fit.

Shielding Exceptions at WCF Service Boundaries using Microsoft Enterprise Library 4.1

To enable the exception shielding feature in my WCF service I have done the following steps Added references of the following assemblies: Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.dll Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.WCF.dll Microsoft.Practices.EnterpriseLibrary.Common.dll Microsoft.Practices.ObjectBuilder2.dll Added a Using statement for Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.WCF. Added the ExceptionShielding attribute to a service implementation class and specified the name of the exception policy to use as a constructor parameter. Add the Exception Handling Application Block configuration sections to the service's Web.config file. <add name="WCFServicePropogate">         <exceptionTypes>           <add type="System.Exception, mscorlib, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089"             postHandlingAction="ThrowNewException" name="Exception">             <exceptionHandlers>               <add exceptionMessage="I created the exception" faultContractType=

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?

Should I use Microsoft Enterprise Library


Hi everyone,

I need to know if it is advantageous to use Microsoft Enterprise Library. I'm gonna use it mainly for it's Data Access Application Blocks. My web application needs to access 3 SQL Server (only) databases, one of which for almost all database accesses and the other two at specific points of a process.

I also want to know how the enterprise library handles the connection to the database, i.e. does it automatically open and close the connection by using the DatabaseFactory.CreateDatabase method and a dataset to be filled with the results? Does it handle the multiple simultaneous database accesses?

what is the difference between using DAAB and old fashion open connection- execute command - close connection In terms of performance and load of database connections?

Thank you so much for your help in advance 

Connection pooling issue with microsoft enterprise library in mysql

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.

Microsoft's Collaborative Application Markup Language (CAML) Loop

discovered an interesting error recently while working with Microsoft's Collaborative Application Markup Language (CAML) that, surprisingly, had received no ink. Partly what surprises me about this is that the error may require you to rewrite large sections of your code if you haven't previously considered this SharePoint limitation. I'll start with some context, but first of all the error is:

MVC architecture in ASP.Net using C# and Microsoft Data Access Application block

The Model-View-Controller (MVC) pattern separates the modeling of the domain, the presentation, and the actions based on user input into three separate classes [Burbeck92]:

Model. The model manages the behavior and data of the application domain, responds to requests for information about its state (usually from the view), and responds to instructions to change state (usually from the controller).

View. The view manages the display of information.

Controller. The controller interprets the mouse and keyboard inputs from the user, informing the model and/or the view to change as appropriate.

Creating a Smartphone Application and Using Data from SQL Mobile

In this exercise, you will use Visual Studio 2005 to create a Smartphone application. You will associate commands with a mobile device's soft keys, and you will add the ability to scroll through the list of available products (a list of images). You will create a data source for an existing SQL Mobile database, and then test the application in the Windows Mobile 5.0 emulator.

In the following procedure, you will create a new Windows Mobile 5.0 project in Visual Studio.
