PDB files indexer (using file archive as a repository).

This article explains the details of the session management in NHibernate. It shows you how, using the debugger, you may examine session properties and check if it's opened and closed in a desired way.

I don't need to stress how tracing (logging) is important in any application. Without logs we are often unable to diagnose the cause of the failure. Logs also help us to track the application behavior and usage over time. Fortunately … Continue reading →

In this part I will show you how to load module debugging symbols (PDB files) into the debugger and how to bind them with source files. This can’t be achieved without diving into process, thread and module internals so we … Continue reading →

The Global.asax file and its role in ASP.NET applications

In today’s post I will describe different security settings of the application pool and the IIS6 directory. It’s not always easy to guess which permissions must be set on system folders and files in order to make the application run … Continue reading →

Making elmah.axd, a log viewer for multiple applications.

ASP.NET Health Monitoring is one of the framework gems that any ASP.NET web developer or web server administrator should be aware of. It provides great monitoring features, often allowing you to rapidly diagnose failing applications or systems. Have you ever … Continue reading →

Writing a .NET debugger (part 1) – starting the debugging session

In this post, I would like to present you a simple way to implement changelog system for database objects using NHibernate session interceptor and database triggers.

In this post I will show you an interesting problem that we experienced when querying a SQL Server database with Dapper.

The article describes how to make a slideshow in a debugger. It may help you understand the PDB api in System.Reflection.Emit as well as impress listeners on any debugging-related presentations:)

I recently needed to diagnose an interesting problem with one of our Topshelf’s Windows Services. The service ended in a StopPending state and we needed to kill it in order to make it work again. But before killing the service … Continue reading →

After the last part, the mindbg debugger stops at the application entry point, has module symbols loaded and displays source code that is being executed. Today we will gain some more control over the debugging process by using breakpoints. Continue reading →

This article explains how to use the Reference Paths project property to debug open-source libraries referenced by the project.

I wrote a simple extension for the MDbg debugger that adds a watch-trace (wt) command to its shell, allowing you to display and customize the method call trees. In this post I’m going to show you how this extension was built and how it can be used.

I have been playing recently with the ETW (Event Tracing for Windows). One of my aims was to write a managed provider and try the ETW infrastructure in my application. Everything seemed to be well explained on the MSDN and not very hard to implement (especially in my simple case). Unfortunately not

How to configure the SqlDatabaseTraceListener to work with a MySQL database.

How to diagnose ADO.NET with ETW traces

In this post I will show you how to create a very simple Windows Service (I will call it Musketeer) that will collect information about other processes running on a server. Such a tool might be helpful if you host … Continue reading →

Today’s post is dedicated to NLog – one of the logging libraries available for .NET developers.

This post will be short and is inspired by Robert’s comment under my previous post (Thanks for it!). Robert pointed (and I completely agree) that it might be useful to have application assemblies versions listed in the log output. So … Continue reading →

In this post I will describe you an interesting problem that my colleague ran into at work.

In today’s post I will show you how we fought a pesky compilation problem with Razor views in our ASP.NET MVC application.
