Scale Up Enterprise Library Caching Application Block

Posted By:      Posted Date: May 22, 2011    Points: 0   Category :ASP.Net

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.

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).

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.

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" />

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?

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.

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



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?

how to write wrapper for Data block of Enterprise library




I have the following scenario.

The project has 4 layers

1) Business Entities

2)Business Layer


all are separate projects
so lets say

1 )Business Entities has

public class Employee
public int EmpId{get;set;}
public string EmpName{get;set}
pullic int Age{get;set;}

2)Business layer will call dataacess layer

public class BusinessLayer

public int RegisterEmployee(Employee objEmp)
 Datalayer objDal =new Datalayer();


3)From the datalayer i need to call Wrapper for enterprise library and the requirement is
datalayer should not have any reference of Enterprise library data block(that i dont know how to do that)
Only the wrapper class should have reference for Enterprise library data block


public class Datalayer
 public int AddEmployee(Employee objEmp)
///Database db=DatabaseFactor.Createdatabase()
//the above line should not be in datalayer it should in some other componenent
//lets say component is wrapper
//i want to how to write wrapper for that.
//As well as how to build command and parameter



VseWSS 1.3 Deployment error related to Enterprise LIbrary(Exception Handling block)


We are getting the folllowing error while deploying VseWSS 1.3. There seems to be an issue with Exception Handling Block.

There no more detail in log file except for this error as shown below. We did a complete reinstall of VS 2008 and VseWSS and Enterprise Library, but the error persist.

Is there some incompatibility issue with VseWSS 1.3 and EL? Has anyone come across this error before:



Microsoft.SharePoint.Tools.Utilities.VSeWSSServiceException: VSeWSS Service Error: The current build operation (build key Build Key[Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.ExceptionPolicyImpl, CommonErrorPolicy]) failed: Object reference not set to an instance of an object. (Strategy type ConfiguredObjectStrategy, index 2)

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.

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?
