Log4net Implementation in CRM 2011, log4net in CRM Plugins, WebServices and Custom aspx Pages.

This post is about log4net logger implementation in CRM 2011. I will provide details about log4net in CRM Plugins. It is as the same with Web-services and Custom aspx Pages.


1. First we will have a Config file for log4net so that, its configuration/settings can be read and applied to logger.

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
  </configSections>
  <log4net>
    <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
      <file value="D:\Logger\Log4net\logs\log.txt" />
      <appendToFile value="false" />
      <rollingStyle value="Size" />
      <maxSizeRollBackups value="5" />
      <maximumFileSize value="1GB" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date [%thread] %-5level %logger - %message%newline" />
      </layout>
    </appender>
    <appender name="MemoryAppender" type="log4net.Appender.MemoryAppender">
    </appender>
    <root>
      <level value="Info" />
      <appender-ref ref="RollingLogFileAppender" />
      <appender-ref ref="MemoryAppender" />
    </root>
  </log4net>
</configuration

Copy all this into a file named "log4net.config" and place it in D:\Logger\Log4net\Config\

2. Add log4net.dll to your Plugin.

3.

using log4net;
using log4net.Config;
public class MyPlugin: IPlugin
    {
    protected static readonly ILog Logger = LogManager.GetLogger(typeof(PublishToGRID));
    static MyPlugin()
    {
      XmlConfigurator.Configure(new System.IO.FileInfo(@"D:\Logger\Log4net\Config\log4net.config"));
    }
try
{
if (context.InputParameters.Contains("Target") && context.InputParameters["Target"] is Entity)
{
  Logger.Info("Plugin Executed");
}
}
catch (Exception ex)
{
  string ErrorMessage = "Exception Occured in CRM";
  Logger.Error(ErrorMessage,ex);              
}

After your plugin executed: you will se the log file generated in D drive.
containing the following text:

Logger.info: 6/15/2014  7:11 p.m
Plugin Excuted

Bridge Inspection and Management system in Asp Dot Net (.NET C#) with Source Code and Database in MS Sql Server 2008

I have developed Bridge Inspection System using Visual Studio Web-Site Project in Asp.net with C#, using my own CSS styling.
Database: in Microsoft SQL server 2008 R2.
Above is the Main Screen, Default Page.
Following are features in this Bridge Inspection System:

• Admin who can add more admins,Collectors,Inspectors and Bridges to be inspected in  System
  Delete Collectors, Inspectors and Bridges from the System.
• Bridge Inspector who can Inspect the Bridges that are currently added and make a report
• Bridge Collector who can View the final Reports added by BI.
• Reports Generation from Inspected Bridge Data and Export Reports in PDF format to be ready for download and printing.
• Profile Management.
• and more ..........................
• Sql Server 2008 Database, Normalized and Complete Relationships.

Following are some screen-shots of the system.
