.NET 10.0.5 Out-of-Band Release - macOS Debugger Fix

We are releasing .NET 10.0.5 as an out-of-band (OOB) update to address a regression introduced in .NET 10.0.4.

What’s the issue?

.NET 10.0.4 introduced a regression that causes the debugger to crash when debugging applications on macOS using Visual Studio Code. After installing .NET SDK 10.0.104 or 10.0.200, the debugger could crash when attempting to debug any .NET application on macOS (particularly affecting ARM64 Macs).

This regression is unrelated to the security fixes included in 10.0.4.

Who is affected?

This issue specifically affects:

macOS users (particularly Apple Silicon/ARM64)
Using Visual Studio Code for debugging
Who have installed .NET SDK 10.0.104 or 10.0.200 or .NET 10.0.4 runtime

Important

If you are developing on macOS and use Visual Studio Code for debugging .NET applications, you should install this update. Other platforms (Windows, Linux) and development environments are not affected by this regression.
