Description

Problem Description

Run init-windows new arch template command

Steps To Reproduce

Clone react-native-webview Run init-windows new arch template command Check the .h boiler code and included native codegen file name

Expected Results

For example in webview .h file, it adds below #include "codegen/NativeReactNativeWebviewSpec.g.h" instead the expectation was below #include "codegen/NativeRNCWebviewModuleSpec.g.h"

Workaround is to manually rename and fix it but ideally the script should support correct naming of include files

Fix init-windows new arch command in codegen that when it creates the boiler .h file it should include the correct nativemodulespec.g.h file name check from path

Research direction
The bug is in the codegen script that runs during the 'init windows new arch template' command. The script generates a .h file with an incorrect include path. The fix involves modifying the script to correctly determine the native module spec file name from the module's path. Check the codegen implementation in the react native windows repository, specifically the part that writes the boilerplate .h file. Ensure the include statement uses the correct generated header name, e.g., 'NativeRNCWebviewModuleSpec.g.h' instead of 'NativeReactNativeWebviewSpec.g.h'. The issue has assignees, so coordinate with them before starting work.
