Presented by dotnet, this session features Grégoire Verdier and Noah Falk demonstrating the .NET Events Viewer, a Blazor-based diagnostics tool. They share insights on solving thread pool issues, building community tools, and fostering open-source contributions in the .NET ecosystem.

ASP.NET Community Standup: Building a Better PerfView with Blazor

Featured Presenters: Daniel Roth, Noah Falk, Grégoire Verdier
Hosted by: dotnet

Overview

This ASP.NET Community Standup explores the creation and development of the .NET Events Viewer, a community-driven diagnostic tool built with Blazor. Inspired by a real-world thread pool issue, the tool aims to enhance the developer experience for .NET performance investigations by offering a modern diagnostics interface.

Key Topics Covered

Origin Story: The .NET Events Viewer was conceived as a response to practical challenges in diagnosing thread pool issues within .NET applications. The creators sought a more accessible, web-based alternative to existing tools such as PerfView.
Blazor Implementation: Utilizing Blazor, the tool leverages .NET technology to deliver interactive diagnostics directly in the browser, bringing familiar web UI paradigms to the realm of low-level performance analysis.
Live Demonstration: Grégoire Verdier and .NET diagnostics engineer Noah Falk demo the tool, showcasing features relevant to .NET developers looking to diagnose and visualize application performance issues.
Lessons from Open Source: The presenters reflect on their experiences contributing to .NET and building developer tools in open-source environments. Discussion includes the technical and non-technical aspects of open-source collaboration and how community-driven innovation benefits the entire ecosystem.

Impact and Collaboration

The development journey highlights how individual real-world needs fuel tool creation within the .NET community.
Collaboration between contributors (including Microsoft engineers and community members) demonstrates the importance of open-source efforts in the evolution of developer tooling and diagnostics.
The session underscores how new tools can emerge when the community is empowered to address gaps and iterate rapidly on solutions.

Community and Further Information

Resource Links: A curated list of links mentioned in the session is available at https://www.theurlist.com/aspnet-standup-20250805.
Hashtags and Topics: Focus includes ASP.NET Core, Blazor, diagnostics, open-source developer tools, and the broader .NET open-source ecosystem.

Takeaways

The .NET Events Viewer project exemplifies how community-driven development within the .NET ecosystem leads to more accessible, robust developer tooling.
Leveraging Blazor for diagnostics tools bridges the gap between traditional desktop performance analysis and modern web-based workflows.
Open-source collaboration not only accelerates innovation but also ensures tools remain relevant to real-world developer needs.

For further discussion and participation, developers are encouraged to engage with the community and explore contributing to projects like the .NET Events Viewer.
