In the .NET development ecosystem, debugging has always been one of the most critical yet elusive capabilities in environments like Visual Studio Code and its supported alternatives. For years, developers who opted for lightweight, modern editors ran into a gap: they could write code, refactor, and run tests, but debugging required opening up a heavy IDE. That barrier has begun to dissipate. The recent update to the ReSharper extension for VS Code, Cursor, and other supported editors brings with it the native .NET debugger that the community has long been clamoring for. This move not only completes the professional toolset for C# in these environments, but redefines the way development teams can work, especially when combining AI-assisted editing and agile DevOps flows.
The lawsuit arose from users working with Cursor, Google Antigravity IDE, Devin Desktop, Kiro, and other forks of VS Code. Microsoft limits the use of its C# Dev Kit extensions to official VS Code, leaving those editors without a first-party debugger. JetBrains' ReSharper has filled that gap with a debug engine based on the same one that Rider uses, optimized for VS Code's debug adapter protocol. This allows you to manage breakpoints, inspect variables, navigate step-by-step, and launch debugging sessions for both new applications and running processes. It includes support for .NET, .NET Framework, and Mono, as well as unit testing. It's a game-changing breakthrough for those who develop custom software and need fast feedback loops.
Beyond the list of features, what's interesting is how this impacts the day-to-day life of developers. For example, in AI-assisted workflows, where code snippets are generated and their behavior needs to be quickly validated, having a built-in debugger saves context switching. Companies like Q2BSTUDIO, which develop custom applications for their clients, understand that the efficiency of the development team translates directly into shorter lead times and higher quality software. Being able to debug from the same editor where the code is written, without relying on additional windows, is a significant advancement that reduces friction and allows developers to focus on business logic.
The new version of the debugger includes conditional, count, and dependent breakpoint management, logpoints, real-time inspection of variables and expressions, and support for attachment to processes. It also makes it easier to set up by reading launchSettings.json and reusing launch.json from other solutions, reducing friction when migrating from Microsoft C# Dev Kit or NetCoreDbg. An important note: only one extension can be the debugging engine per language, so if you have Microsoft's C# Dev Kit installed, you need to disable it to use ReSharper's. This compatibility is key for hybrid environments where different tools coexist.
For companies that adopt agile methodologies and multidisciplinary teams, having tools that unify the development environment reduces cognitive overload. In addition, integration with editors like Cursor, which boost productivity through artificial intelligence, makes debugging even more crucial. When generating code with AI, error checking and correction becomes iterative and fast; A native debugger speeds up that cycle. Q2BSTUDIO, as a technology company, applies these principles in its custom software projects, where quality and speed are differential. It also offers artificial intelligence, cybersecurity, and cloud services that complement .NET development, allowing everything from security auditing to scalable deployment in the cloud.
From a business perspective, debugging is not just a technical tool, but an enabler of productivity. When a team can debug without leaving their editor, downtime is reduced and code quality is improved. In complex projects that integrate AI for enterprises or AI agents, the ability to follow execution step-by-step is critical to understanding the behavior of business models and logic. In addition, in environments where AWS and Azure cloud services are used, the debugger allows you to verify the behavior of cloud applications during local development before deployment, minimizing errors in production.
The update also includes support for unit test debugging, which fits perfectly with test-driven development (TDD) practices and continuous integration pipelines. Developers can set breakpoints in their tests and run them under the debugger directly from the editor, without needing to switch windows. This speeds up fault detection and accelerates feedback in iterative development cycles.
For those working with the legacy .NET Framework, there's a handy caveat: some legacy projects, such as WPF applications, can fail when launched directly from the debugger. The recommended solution is to run the application first and then attach the debugger to the process. This workaround shows that while the support is solid, there are always nuances to know. Q2BSTUDIO, with his experience in AWS and Azure cloud services, often advises his clients on the migration of legacy applications to modern, debuggable architectures.
The release of this debugger is just the beginning. The community has asked for additional features such as support for hot reload, more advanced expression evaluation, and profiling. JetBrains has left the feedback channel open, suggesting that the product will evolve based on the developers' actual needs. For those working in high-demand environments, such as cybersecurity applications or business intelligence systems with Power BI, having a reliable debugger is a non-negotiable requirement.
In conclusion, the arrival of the ReSharper debugger for VS Code, Cursor, and other alternatives marks a milestone in the evolution of .NET development. Developers no longer have to sacrifice functionality for convenience. With this tool, the ecosystem of lightweight publishers is consolidated as a top-tier platform for .NET, capable of competing with traditional IDEs. At Q2BSTUDIO, we understand that tools like this empower the creation of robust and scalable solutions, whether they are custom applications, integrations with artificial intelligence or cloud platforms. We invite professionals to explore this new capability and share their experiences, because debugging is undoubtedly the pillar on which quality software is built.
