Many developers encounter this frustrating issue where changes are detected but not applied. This guide unpacks the problem and presents a straightforward solution to restore your hot reload functionality. The Problem: Hot Reload Not Functioning You may have noticed that after upgrading your IDE, the hot reload feature—designed to save you time and hassle during development—ceases to work. Key symptoms include: Detecting Changes: You might see messages stating "File changed: c:\xxx" indicating that the system recognizes file modifications. No Restart or Reload: Despite the notification, the application doesn't reload as expected when you hit CTRL + R, leaving you needing to restart your development server manually. Environment: Ensure that your application is running on the .NET 6.0.101 framework and take note if this issue arose after the version upgrade. The Solution: Adjusting Launch Settings in Your Project Fortunately, many users have resolved this hot reload issue by simply modifying the configuration within the launchSettings.json file. Here’s how you can do this step-by-step: Step 1: Locate Your launchSettings.json File The launchSettings.json file is typically found in the Properties folder of your Blazor project. Open your project in Visual Studio, and navigate to: [[See Video to Reveal this Text or Code Snippet]] Step 2: Change the Ports Inside the launchSettings.json, look for the profiles section where your application settings are defined. You should see a section resembling the following: [[See Video to Reveal this Text or Code Snippet]] Modify the applicationUrl setting by changing the port number. For example, if it currently reads http://localhost:5000, try changing it to http://localhost:5001 or any other port that isn't being used. Step 3: Save and Restart After you’ve made the changes, save the launchSettings.json file and restart your application. Once your application runs on the new port, test the hot reload functionality again. Why This Works The issue may stem from port conflicts or caching issues in the upgraded Visual Studio environment. Changing the port can help reset any underlying problems that prevent the hot reload feature from functioning properly, providing a fresh context for your application. Additional Tips Keep Visual Studio Updated: Make sure you keep your development environment updated. Sometimes, earlier versions could have bugs that are fixed in subsequent updates. Check the Output Window: The Output window in Visual Studio can provide additional hints or error messages that can help diagnose issues related to hot reload. Community Forums: Engage in various developer forums or communities. You may find that others are facing similar issues and solutions can be collaboratively explored. Conclusion The hot reload feature in Blazor applications can significantly streamline your development process. By adjusting the ports in your launchSettings.json, you may resolve this frustrating issue and restore functionality. If problems persist, consider reaching out to community forums or logging issues with the Visual Studio team. Happy coding!
