Debugging multilevel applications in C#

Just like “Back to The Future” is a movie that is considered to be a symbolic part of the 90s, the same way bugs are inherent in development. It is especially true with multilayer applications where finding a bug may be a real challenge. Even with all kinds of tests, various bugs slip into production now and then. Debugging applications in the production environment can be particularly daunting. How can you inspect them effectively? How do you determine what happened on your clients’ machines? This article contains a short tour of RevDeBug – Time Machine for Visual Studio, which provides innovative tools to help debug applications by tracing and replaying code execution to pinpoint and resolve issues.

Reverse debugging tool for Visual Studio

RevDeBug is a Visual Studio extension for C# frameworks, which allows you not only to implement reverse debugging in your projects but also to monitor them on production. It creates a recording with all application states (values, methods calls, exceptions). With this information, you will be able to easily travel back in time, through every layer of your code. How does it work in practice? We may summarize that to these two steps:

Recording of a session with a bug is being sent automatically from application user to developer.

The developer is prospecting this stream of values to find the root of the problem.

This technology is particularly suitable for multilevel projects, where finding the root of the error may pose a big challenge. It also allows you to work with a problem without laborious bug recreating – as you are working on data straight from production.

Travel in code, in the order of its execution time.

Challenges of debugging multithreaded applications are not simple to face. What’s more, threading problems are notoriously troublesome to replicate. Determining the state of the program at the time of failure can be difficult; understanding why a particular state is problematic can be even more demanding. That’s why reverse debugging technology is such an effective mechanism when it is coming to a crash. RevDebug allows you to track every thread of your application. Check out how it looks in the Visual Studio:

Track every thread of your application, basing on data from production

Track every strand of your application, basing on data from production.

It’s not the only feature of RevDeBug, which supports developers in debugging complex applications. With the latest update, we give you also a call stack and scope stack (which provides fine-grained navigation within the current method and makes it easier to iterate over loops and conditionals).

Scope stack is a tool designed for better navigation within the scope of the particular method, loop, or conditional.

RevDeBug call stack is a tool which gives you detailed information about methods called at runtime from the beginning of a program until the execution of the current state.
