Iis7 Asp.net configuration default document Error

 

The following error occurs when configuring the Asp.net program in iis7:

Configuration error: When the unique key property "value" is set to "default. aspx", duplicate set items of the type "add" cannot be added.
Configuration File

File: // *******/web/Web. config

 

 

 

 

In web. config

<Defadocument document>
<Files>
<Add value = "default. aspx"/>
</Files>
</Defadocument document>

The error occurs because the default document is set to default in IIS. aspx. At this time, Asp.net obtains another add with the same value, causing an exception. The solution is to add <clear/> before <Add/>.

ModifyWeb. config is

<Defadocument document>
<Files>
<Clear/>
<Add value = "default. aspx"/>
</Files>
</Defadocument document>

 

This method applies to any. Net configuration that may produce inheritance obfuscation.
