IIS Express 未在 Visual Studio 2019 中运行

Question

I am new to dot.net development and start developing a web app.

I am developing a chat application under ASP.NET core MVC architecture.

Initially, the project works well and could run on IIS Express. but later I found that now the IDE is not working: the project cannot run on IIS Express.

I am getting the following error as an alert message as well as in the output console.

Error: The program '[18268] iisexpress.exe' has exited with code 0 (0x0).

Screenshot of the alert message in the IDE: Click here to view

But after a while, I restarted the project and when I run the project again, I got the following error:

Error: The program '[17512] iisexpress.exe' has exited with code 0 (0x0).

I am confused what is wrong with my project or IDE. Can somebody please help me to resolve this?

Thanks in advance.

I already refer some posts and articles in stackoverflow and internet but could not see the problem I found some posts I have already followed:

https://stackoverflow.com/questions/62745345/error-running-iis-express-in-visual-studio\ IIS express crashes after successfully debugged and build

But they are very old posts and I could not find an answer.

1. Check your solution folder for a hidden ".vs" folder.

2. In Visual Studio, right click on the web project, chose properties and then navigated to the "web" tab. From there I changed the Project URL to another port number. For example, if it was http://localhost... - Changed it to http://localhost:43567.

3. If your machine is 64bit, please go to Tools-> options -> projects and solutions:
