### Is your feature request related to a problem? Please describe the problem.

When working on a web project that involves a separate shared project which contains route definitions (e.g. with a class named ApiRoutes), the current syntax highlighting support is limited to the web project.

The absence of route syntax highlighting in the shared project makes the development experience worse and challenging to have a consistent setup across projects.

### Describe the solution you'd like

To address this issue effectively, it would be beneficial to provide developers with the option to choose whether they want to enable syntax highlighting for route definitions in shared projects (for example through NuGet packages).
This flexibility ensures that developers can tailor their coding environment to best suit their preferences and workflow requirements.

### Additional context
**Current workaround:**
To get syntax highlighting for routes in non web projects you can add ```` to your ``.csproj`` file.

Sample:
```xml

net8.0
enable
enable

```
