Introducing Glass.NET — a free .NET decompiler you can navigate
Glass.NET is a free .NET decompiler that turns any assembly into clean, readable C# — with fast Go to Definition, Find All References, Go To All, call/type hierarchy, C#/IL views and project export. A modern ILSpy, dnSpy and .NET Reflector alternative.
Today we’re releasing Glass.NET, a free .NET decompiler from Delta1 Labs — and the second product in our developer-tools suite alongside Nebula.NET.
Glass.NET turns any compiled .NET assembly back into readable C#. What makes it different is the experience: reading an unfamiliar assembly feels like reading your own source — you navigate it, you don’t just scroll it.
Why another decompiler?
Decompilers like ILSpy, dnSpy and .NET Reflector have served the community for years. But most of them show you code and leave you to scroll. When you’re deep in an unfamiliar assembly, what you really want is to navigate — to press F12 and land on a definition, to find every caller of a method, to jump to any type by name.
Glass.NET is built around that: press F12 to land on a definition, find every caller of a method, or jump to any type by name.
What’s in the box
- Go to Definition (F12), plus Ctrl+Click and double-click, on any symbol.
- Find All References (Shift+F12) streaming into a Find Results panel.
- Go To All (Ctrl+T) — fuzzy quick-open across every type and member.
- Navigation history (Ctrl+- / Ctrl+Shift+-) and a namespace ▸ type ▸ member breadcrumb.
- C# and IL views, code folding, and matching dark and light themes.
- Export to a buildable project (in the app or the
glass exportCLI), side-by-side assembly compare with a line diff, and an exposure report. - Real speed — lazy loading and off-thread decompilation keep it responsive on assemblies with thousands of types.
Under the hood, Glass is powered by ICSharpCode.Decompiler, the proven engine behind ILSpy, so the C# it produces is accurate and up to date with modern language features. And it’s strictly static analysis — Glass never runs the assembly it inspects.
Free, forever
Glass.NET is completely free — no license, no seats, no sign-up. Grab the latest build from the download page or the releases repository, open an assembly, and press F12.
