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)

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.

Having Enterprise Library 5.0 use app.config



I have a Solution which contains a Web project and a Class Library project. The Class library project contains Enterprise library 5.0 and app.config. When I try to perform a Microsoft.Practices.EnterpriseLibrary.Logging.Logger.Write, I get the following exception:


Resolution of the dependency failed, type = "Microsoft.Practices.EnterpriseLibrary.Logging.LogWriter", name = "(none)". Exception occurred while: while resolving. Exception is: InvalidOperationException - The type LogWriter cannot be constructed. You must configure the container to supply this value. ----------------------------------------------- At the time of the exception, the container was: Resolving Microsoft.Practices.EnterpriseLibrary.Logging.LogWriter,(none)


If I move all the class files to the web project and have the Enterprise library configuration in the Web.config, everything works fine. I guess the issue is that the Enterprise library is not detecting the app.config which contains all the configuration. How can I have my enterprise library use the App.config present in its prroject.


Kindly help me with this regard.

Thanks in advance.


Every self-respected programmer should include exception handling techniques. Sometimes your application will generate an error. Regardless of who was responsible for this error, the programmer or the user, it is up to the first to include the necessary exception handling techniques to keep his/her program from crashing. The .Net environment provides useful techniques for avoiding disastrous errors such as try-catch statements and user-defined exceptions.

Global Exception Handling with ASP.NET

After your global exception handler has done its work, you'll want to redirect the users of your website to a friendly page that tells them that something has gone wrong, and then provide them with customer support information as well as a link back to your web application's home page.

SQL Server 2005 Try and Catch Exception Handling

I'm pretty excited to see that there is some real error handling for T-SQL code in SQL Server 2005. It's pretty painful to have your wonderfully architected .NET solution tainted by less-than-VBScript error handling for stored procedures in the database. The big difference being the addition of TRY..CATCH blocks. Let's take a look:

Error while using exception handling block el 4.1


Hi Folks,


i am trying to use tyhe exception handling block of Enterprise library 4.1.


I just createda polisy and used IndexOutOfRangeException and added a replace handler and a logging handler to it.

I am using the NotifyRethrow PostHandlingAction to the exception.


During runtime I am getting an exception on the HandleException event, The exception is added below:



Object reference not set to an instance of an object.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

Source Error:

Line 42:             catch (Exception ex)
Line 43:             {
Line 44:                 bool reThrow = ExceptionPolicy.HandleException(ex, "ReplacePolicy");
Line 45:         

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?

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.


Thanks In Advance.

Using Enterprise Library for first time



I wan to use the enterprise library for the first time. Is there any samples, quick start guide or ebook is available for a quick start and learn the basics.

I have vs2008, so which version of EL should I use?

And if somebody can just brief about Enterprise Library. Because as per my understanding, is this a mixture of design patterns and some pre-made blocks of source code.





Data Points: SQL Server 2005 XML Support, Exception Handling, and More


SQL Server 2005 includes several important improvements to the Transact-SQL (T-SQL) language. One added feature is a new kind of trigger that fires when data definition language (DDL) statements run.

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.
