Current Issues with Hermes Direct Debugging

[TatianaKapos]

Problem Description

In React Native Windows, we've observed a regression in Hermes Direct Debugging across versions 0.72.x, 0.73.x, and 0.74.x. While we're actively working on a patch for these versions, we recommend using Web Debugging as an alternative while this issue is still open. You can find instructions for Web Debugging here. Thank you for your patience as we work to get a fix out!

Current Open Issues

• 1. Variables in watch window are not evaluated when direct debug RNW apps using the Hermes JS engine #12654
• 2. Can't direct debug Hermes when consuming the Microsoft.ReactNative nuget packages #11252
• 3. RNW instances using Hermes should support direct debugging in release builds #10245
• 4. [Fabric] Apps using bridgeless mode do not enumerate direct debugging targets #12834
• 5. Unable to debug RNW app (Hermes Direct Debugging) with Visual Studio 2022 (17.9.3) if the native solution is open #12842

Unfortunately, Web Debugging is not an option for those who want to use synchronous calls to native module methods according to https://microsoft.github.io/react-native-windows/docs/debugging-javascript#web-debugging

Furthermore, some parts of RN, such as synchronous calls to native module methods, only work when running on the embedded JS engine. Such native methods won't work when using Web Debugging.
