Configuring traces in WCF service

Some times we fail to find what could have caused our WCF service to fail. This can be easily tracked by powerful tracing feature which can be enabled in config file. Traces can be viewed in Trace file viewer which comes with windows sdk elegantly.
For enabling trace use following in WCF service config:
<system.diagnostics>
  <sources>
    <source name="System.ServiceModel" switchValue="Warning, ActivityTracing" 
            propagateActivity="true">
      <listeners>
        <add type="System.Diagnostics.DefaultTraceListener" name="Default">
          <filter type=""/>
        add>
        <add name="ServiceModelTraceListener">
          <filter type=""/>
        add>
      <listeners/>
    source>
   
  <sharedListeners>
    <add initializeData="c:\wcfLogs\SomeService\app_tracelog.svclog" 
         type="System.Diagnostics.XmlWriterTraceListener, System, Version=2.0.0.0, 
         Culture=neutral, PublicKeyToken=b77a5c561934e089" name="ServiceModelTraceListener" 
         traceOutputOptions="Timestamp">
      <filter type=""/>
    <add/>
  sharedListeners>
system.diagnostics>

The path "C:/Log/" should exist on disk.

You can also specify what type of messages you want to log using

<diagnostics>
      <messageLogging logMalformedMessages="true" logMessagesAtTransportLevel="true"/>
    diagnostics>
inside "ServiceModel" tag.
Hope this helps!!!

Inversion of control in 3 layer architecture

Image
While designing layered application we typically follow following structure: In this traditional approach UI layer refers to Business access layer(BAL/Controller layer) and BAL refers to Data access layer (DAL). This referring is usually hard coded at each layer leading to numerous problems simply because of the reason that we don't program to abstraction. The problem which could crop up are: Data access layer is not interchangeable. Suppose in future in stead of storing data to data we choose flat file storage, so in order to accommodate this in current layering BAL and DAL both has to rebuilt. Its not easy to test the whole system without each and every component up and running. In short its not east the fake the data layer or controller layer to test the same using automated tests. Its not easy to share the business rules across application or modules as they are dependent on the lower layers directly. Business rules are generally shared across all the systems despite...

Singleton pattern for logger class

Implementing Singleton Design pattern for logger service is something used extensively. Here is the implementation which i used recently:     class Logger     {         #region Private member         //Stream writer to write log to file.         private static StreamWriter streamWriter = null;         //Will be used in synchLock to make initialisation thread safe.         private static Object synchLock = typeof(Logger);         private static Logger logger = null;         //Log file name.         private const string LOG_FILE_NAME = "Log.txt";         #endregion         #region Constructors ...

Consistent Response Validation - Invalid Value for types & Business Rules in Web API

Image
Fluent validation is a great library to perform validation on objects. Integrating fluent validation in .net core is very simple and minimal steps are described along with a way to make validation response consistent be it binding error or business validation error. Steps  1. Add a reference to NuGet package      <PackageReference Include="FluentValidation.AspNetCore" Version="8.4.0" /> Adding sample validator Person Validator 3. Validating Object Validating Object This works fine and the correct error message is displayed. Fluent Validation Error Message response However, consider the request where  Date of Birth  of person is passed as an invalid date. In this case, controller method gets  null  as input because of invalid type value during the model biding phase. By default below error message is thrown if model state is validated in the controller method Default Model State Error In t...
