Glimpse v2 Beta1 Released!

This morning at the Connect(); event in New York city, Scott Hanselman announced some exciting news: Glimpse v2 Beta1 is now available!

Glimpse v2 is a major evolution of the platform. We’re extremely proud of what we’ve accomplished thus far, and we think you’ll like what you see. You’ll find lots of new bells and whistles that make Glimpse better than it ever has been, but I’d like to outline four key improvements to the Glimpse v2 experience.

Curated UI

Glimpse has always been about getting the diagnostics you need, when and where you need them. However, one of the most overwhelming pieces of feedback we have received over the years is that beyond the Heads-Up-Display, those diagnostics were not necessarily well presented and were sometimes difficult to parse.

In v2 we’ve strived to solve these issues by curating disparate data points from across multiple tabs and pulling them together into one cohesive story. We’ve also allowed diagnostics to become the real star, freeing them from the cramped space you’re used to seeing them in, and giving them the full window treatment they deserve; which coincidently makes switching between requests much easier than it was in v1. Take a look for yourself:

Cross Platform

Glimpse v2 is built completely upon ASP.NET 5 API’s, concepts and the CoreCLR. This means that Glimpse v2 automatically inherits all of the benefits of ASP.NET 5, including its ability to run cross platform on Windows, Linux and OSX.

Now everywhere you can run your site, you’ll be able to use Glimpse v2 to debug and diagnose it as well.

Full Stack

Since its inception, Glimpse has been known as “F12 tools for your server”. But as you’ll no doubt know, web development doesn’t happen only on the server.

With this in mind, Glimpse v2 has begun to leverage new browser diagnostic API’s to tell a more complete, full stack story. You’ll now be able to glean insight into some of the processing happening in the browser, right in the context of your server side diagnostics, for many request.


Production Ready

Glimpse really shines during development time. Its ease of installation and use is what’s made Glimpse v1 a favorite among web developers for years. Unfortunately, in many situations Glimpse did not work well once your application was pushed to production.

In Glimpse v2, this all changes. A much larger class of applications will now be able to use Glimpse in production environments to debug and diagnose problems in real time.

In the coming weeks we’ll devote more of this blog to covering the ins and outs of these four key features, as well as other changes, and cover exactly what they mean for you.

βeta Beware

Of course, it wouldn’t be responsible for me to cover all of the greatness that is Glimpse v2 without also reviewing its current limitations and known issues.

First of all, what we’re releasing today is an early beta build meant for gathering feedback from users and extension authors. It may have a few rough edges, the user interface is a work in progress and it certainly isn’t feature complete. Look for more stable builds, improved UX and the re-introduction of beloved features such as Timeline and the Trace tab in the future.

It’s also worth noting that Glimpse v2 Beta1 only runs on ASP.NET 5. While using the latest and greatest does have its own perks, for existing applications you’ll need to stick with Glimpse v1. That also means that Glimpse v1 extensions are incompatible with Glimpse v2. In the future we’re going to bridge this gap so that everyone, including .NET 4.5 and .NET 4.0 users will be able to benefit from the new features of Glimpse v2.

Next Steps

Over the next several weeks, keep an eye on this blog and our GitHub repository where we’ll continue to improve Glimpse v2, support and update along with ASP.NET 5 and march towards a full, final 2.0 release.

In the mean time, install Beta1 and give it a try.

We really hope that you enjoy this release and are excited about the direction Glimpse is going, but more than anything else, we’re excited to hear your feedback.

    This is great new. I hope you will log more about the extensibility story for v2 and also how you’re plugging into AspNet 5 diagnostics APIs
