Enterprise Library 5.0 Beta1

I would like to share the way to configure the logging application block with a sample web application to log the errors to the Event Listener and to a log file.

Once you have installed the Enterprise Library 5.0 Beta1 into your machine make sure to make it as strong named it by applying a key using the Visual Studio.

After that add a reference to the logging application block assembly : Microsoft.Practices.EnterpriseLibrary.Logging.dll in your project.

the next step is to configure the Logging Application Block using the Enterprise Library tool located under Program Files => Microsoft patterns & practices => Enterprise Library 5.0 Beta 1 – February 2010 => Enterprise Library Configuration.

so the Configuration tool open like below :

image

Open your web.conf or app.conf file using the above tool as below:

image

by default it will list you the Application Settings and the Database settings and it does not contain anything and if you need to configure something on that feel free to add those values.

image

As we need to test the logging application blocks, please add the Logging Application Blocks by clicking Blocks => Add Logging Settings as below.

image

so it will lists you the settings as below :

image

Enter a name for your Event Log listener as below:

image

Under All Events settings make sure to add your recently created listener into the list as below:

image

Click the “+” sign next to the Logging Target Listeners and select Add Logging Target Listeners => Add Flat File Trace Listener.

image

Once you add the Flat File Listener the configuration tool will looks like below:

image

After that select the log file name to log the events and the Formatter as Text Formatter.

image

image

Upon making the above settings make sure to add the above listener to the All Events settings as below :

image

Upon following the above steps write the following code in C# and test the solution, you will find the entries written upon in the Event Log and the Log file which you did specified in the above step :

try
{
LogEntry logEntry = new LogEntry();

logEntry.Severity = System.Diagnostics.TraceEventType.Information;
logEntry.ProcessName = "Section XYZ from your project";
logEntry.Title = "Testing";
logEntry.Categories.Add("General");
logEntry.Message = string.Format("Your Message");
logEntry.TimeStamp = DateTime.Now;               
Logger.Write(logEntry);
}
catch (Exception ex)
{
Response.Write(ex.Message);
}

Consuming a Web Reference in a class library (C#/.NET) – VS 2008

when you tried to add a web reference to a Class Library in VS 2008, by default it will add a Service Reference (WCF). I have seen this option only in VS 2008 and not in VS 2005. If you need to add a Web Reference then at the time of adding a Service Reference, click the Advanced button as depicted below :

image

After that click the Add Web Reference as below:

image

after that you will be prompted with the usual add web reference dialog.

Setup says VS Integrated Shell 2010 ENU installed when uninstalled, Grrrr!!!

I came across a situation where i had to remove the Team Explorer version 2010 Beta1 from my machine. I have uninstalled it via Uninstall option from the Programs and Features. When i tried to install TFS 2010 RC Team Explorer setup it says “VS Integrated Shell 2010 ENU” exists and have to remove. I did the uninstallation and restarted the machine even. Nothing happened and when i ran the installation it prompts me again saying that “VS Integrated Shell 2010 ENU” already exists. I checked the Programs and Features and it was not there. 😦

I was something like this :

image

finally found the solution.

simply run this command :

msiexec /uninstall {874D5E2B-AACE-303A-B3EC-2563E071473E}

lets we dig little bit deeper in to the above command.

Initially you have to to do is to use msiinv.exe (thanks to Aaron Stebner’s to exposing the tool) tool to see if MSI thinks the integrated shell is installed or not. So from that tool it will lists all the installed programs and under that list you can see this ghost “VS Integrated Shell 2010 shell ENU” still exists in the list.

what you have to do is just note down the Product Code and use the same code to execute the above command.

Team Foundation Server 2010 RC Installation

After a lengthy hard work we were able to install and configure the Team Foundation Server 2010 RC on Windows 2008 R2. Eventhough the installation and the configuration is easy we had some trouble with the DNS naming of the host machine (thanks to Usman – Team Lead to identifying that issue).

kick off the installation by clicking the setup file and follow the screens just clicking the next button.

After the completion of the installation its time to configure the TFS 2010.

In this situation you have to enter a authenticated user who has the administrator rights in the domain.

from the following screen you can double check all your entries are valid or not by clicking the Verify button. Its one of the best feature in this configuration wizard rather messing up the things after the completion of the installation.

VS 2008 SP1 ISO image

when we are installing VS 2008 SP1, initially we can download a .exe from the microsoft site and upon executing that file we should have the internet connection as it fetches all the latest patches online.

if we need to apply the same SP1 to multiple machines then it will be really a headache, so rather doing like that from the following link we can download the ISO image file.

You must use the Role Management Tool to install or configure Microsoft .NET Framework 3.5.

When you are trying to install Visual Studio 2008 professional edition on a Windows 2008 R2 suddenly you will be prompted to an error saying “You must use the Role Management Tool to install or configure Microsoft .NET Framework 3.5.”



In this case what you have to do is, from the Service Manager install the .NET Framework 3.5.1 Feature as Windows 2008 R2 is integrated with .NET Framework 3.5.


so before installing VS 2008 make sure that you are enabling this feature .NET Framework 3.5.1 Features via the Add Features Wizard in Server Manager.
