TypeScript breakpoints not working when debugging example project

[vitaliy00000]

Describe the bug
When debugging the example project from this repository, TypeScript breakpoints do not work in the original .ts source files. The debugger only stops on breakpoints if they are set in files shown under the Script Documents section in Visual Studio.

To Reproduce
Steps to reproduce the behavior::

1. Clone the repository
2. Open the example project in Visual Studio
3. Build the project
4. Start debugging
5. Set breakpoints in the original TypeScript (.ts) files
6. Observe that breakpoints are not hit
7. Set breakpoints in files under Script Documents
8. Run the debugger again and see that breakpoints are hit

Expected behavior
Breakpoints set in the original TypeScript source files should be hit during debugging without needing to use files from the Script Documents section.

Device (please complete the following information):

• OS: Windows
• IDE/Editor VS 2026

Hi. That seems more like a configuration issue with VS 2026.
If the Vite development server is already enabled, then the IDE is not being attached to the browser.

Edit: the docs also says the following:

For debugging a client-side script in ASP.NET apps, open the Tools > Options pane and expand the All Settings > Debugging > General section. Select the Enable JavaScript debugging for ASP.NET (Chrome and Edge) option.
