I decided to publish the ASP.NET MVC project to test it locally using IIS Manager. Therefore, after opening the necessary windows features, I created a new folder in the C:\inetpub\ directory on IIS Manager:

In the Visual Studio IDE I right clicked on the solution and clicked "Publish..." and specified that the target was "Folder":

When I clicked the Next button, I specified in the next window that the "Target" location was the C.\inetpub\TechnologyArticle directory. Then when I clicked the "Publish..." in the Visual Studio IDE, I encountered an error that I did not receive in Debug mode:

System.AggregateException: One or more errors occurred. 
---> Microsoft.WebTools.Shared.Exceptions.WebToolsException: Build failed.

---> (Inner Exception #0) Microsoft.WebTools.Shared.Exceptions.WebToolsException: Build failed.

---> Microsoft.WebTools.Shared.Exceptions.WebToolsException: Build failed.

How can I solve this problem? Is the reason why I got this error in Release mode, which I did not receive in Debug mode, due to programming?

CodePudding user response：

This error is not due to programming. The reason for this error is trying to publish the website in the C:\inetpub\ directory, which is made visible and/or created by a service that you have activated by "Turn Windows features on or off" to publish the ASP.NET website locally. The user has no right to modify the C:\inetpub\ directory. Therefore, the current user's right to modify the C:\inetpub\ directory must be declared manually in the Windows 10 operating system.

When the ASP.NET website is published, the project outputs (such as *.dll files, style files, scripts, Views) compiled in Release mode will be extracted to the target directory, so the user must have the right to write to the C:\inetpub directory.

To resolve this issue, follow the steps below:

• Open the properties of the C:\inetpub folder (With the folder selected, use the ALT ENTER shortcut).
• Switch to the Security tab and click the Edit button.
• Define "Full Control" right for current user and confirm settings by clicking OK button.
• You repeat the publish procedure to publish your website.
