Microsoft Enterprise Library 5.0 - Logging Application Block Activation Error

Posted By:      Posted Date: October 15, 2010    Points: 0   Category :ASP.Net

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?

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.

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.

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

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)

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.

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.

Data Truncation issue with Enterprise Library Logging WriteLog stored Proc


Hi ,

I'm using Enterprise Library Logging  feature for logging. The issue i am facing is when the Logging message is too large(more than 65534 chars) ,complete data  is not logged in the Formatted Mesage column which is  of data Type nText .

I am able insert complete data if i try inserting from Sql insert Query from sql management studio. Do i need to add any attributes to data base listener or do i need to change the sp.

 Is there any way to increase the WriteLog stored proc param size in EnterpriseLibrary.Logging config file ? . Please let me know.

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.

Enterprise Library 3.1 database logging


Im new in using Microsoft Enterprise Library 3.1. Im trying to run database Logging.
I added the required configuration to the web config as mentioned in MSDN library. then I ran the script to generate logging tables and stored procedures.

I changed the formatter template to keep needed data. below is sample of my code

Dim ologEntry As LogEntry = New LogEntry()
        With ologEntry
            .Severity = Diagnostics.TraceEventType.Error
            .Title = "MSEntLib3.1"
            .AppDomainName = AppDomain.CurrentDomain.BaseDirectory
            .ProcessName = "TestFunction()"
            .Message = "Informational message"
        End With


I faced an error that there are missing paramters then I modified writeLog stored Procedure to recieve the listed above paramaters, I test it on sql server its working fine, in my web page it doesnt rais an error and not inserting any data to the log table.

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=
