How I Fixed Unity Debugging Issues After Switching to Anysphere C# in Cursor

I use Cursor IDE every day as a Unity developer, so when a C# language server update broke my debugging, it stopped me in my tracks. Suddenly, my Unity projects wouldn’t debug properly. I needed a solution quickly. Here’s exactly how I fixed it and got back to productive coding.

The Problem That Stopped My Workflow

When C# and C# Dev Kit switched to Anysphere C#, my Unity extension stopped working with the new language server. Overnight, I couldn’t set breakpoints or check variables during runtime.

Debugging is my safety net. Without it, I was coding blind – guessing where bugs might be hiding. My productivity plummeted, and frustration mounted with every failed test run.

Discovering the DotRush Workaround

After digging through forums, I learned the official Unity extension doesn’t play nice with Cursor anymore. That’s when I found DotRush – an alternative extension other developers recommended.

What caught my eye? DotRush specifically addressed the Anysphere C# compatibility issue. It promised to restore Unity debugging without messy workarounds.

Step-by-Step: How I Made It Work

Getting everything running took some experimenting, but this sequence finally worked for me:

• Uninstalled Microsoft’s C# extension first (this prevents conflicts)
• Added DotRush from the marketplace
• Installed Anysphere C# last
• Restarted my workspace – debugging magically worked again!

I did get one conflict warning during setup. Reinstalling in this exact order cleared it up.

If you see alerts, just verify only DotRush and Anysphere C# are active. Minor warnings didn’t impact functionality for me.

Why This Solution Transformed My Coding

DotRush didn’t just restore debugging – it improved my workflow. The extension feels lighter than the old setup, with no random freezes.

I even gained new capabilities, like viewing outer stack variables during breakpoints. Unexpected bonus! Now I reach for DotRush automatically when working on Unity projects in Cursor.

My Advice for Fellow Developers

If you’re stuck with Unity debugging in Cursor after the Anysphere switch, try DotRush. Stick to the installation order I used, and remove any conflicting extensions first.

This simple fix saved me countless hours. My debugging now works smoothly, letting me focus on building rather than troubleshooting.
