这个浏览器F12查看后台请求，发现有一堆js文件没有加载。

而这些文件，在项目路径\wwwroot\lib下。所以，需要publish站点，再运行exe。

When deploying an ASP.NET Core application to IIS, there are two common deployment models: IIS Site and IIS Application. The behavior you described, where the JS files are found under the wwwroot/js folder when deployed as an IIS Site but not as an IIS Application, can be explained by the way IIS handles static file serving in these deployment models.

IIS Site Deployment: In this model, the ASP.NET Core application is deployed as a standalone website in IIS. The root folder of the website is set to the wwwroot folder of the application. When a request for a static file like a JS file is received, IIS looks for the file in the configured root folder (i.e., wwwroot/js) and serves it directly. This is the recommended deployment model for ASP.NET Core applications.
IIS Application Deployment: In this model, the ASP.NET Core application is deployed as an application within an existing website in IIS. The application is typically mapped to a subdirectory or a virtual directory within the website. When a request for a static file is received, IIS processes the request based on the application's configuration. By default, it does not serve static files from the application's root folder (wwwroot) directly. Instead, it passes the request to the ASP.NET Core runtime, which handles static file serving based on the configuration in Startup.cs. This adds some additional overhead and configuration complexity compared to the IIS Site deployment model.

If you are experiencing issues with the IIS Application deployment model not finding the JS files in the wwwroot/js folder, it could be due to misconfiguration or a difference in how static files are being served. You may need to adjust the configuration in your Startup.cs file to ensure that static files are correctly handled and served by the ASP.NET Core runtime.

To troubleshoot the issue, you can check the following:

Ensure the UseStaticFiles middleware is properly configured in your Startup.cs file:

csharp

app.UseStaticFiles();
Verify the file path references in your HTML or Razor views. Make sure they are correctly relative to the application's root URL, considering any subdirectory or virtual directory mappings.
Check the application's configuration in IIS to ensure it is correctly mapped to the appropriate physical path and that the necessary permissions are set.

By addressing these factors, you should be able to resolve the issue and successfully serve the JS files under the wwwroot/js folder in an IIS Application deployment.
