HTTP 错误 500.19 - IIS Express 中的内部服务器错误？

Question

My ASP.NET site is working well in VS 2015.

But I have published it to IIS Express in Window 7, displays the below error.

That is my IIS Express config.

What's my wrong?

Answer 1

If you google your error, literally first result is this support page

And the very first entry is:

HResult code 0x8007000d

Error message :
Server Error in Application "application name" Cause HTTP Error 500.19 – Internal Server Error HRESULT: 0x8007000d The requested page cannot be accessed because the related configuration data for the page is invalid.

Cause : This problem occurs because the ApplicationHost.config file or the Web.config file contains a malformed XML element.

Resolution : Delete the malformed XML element from the ApplicationHost.config file or from the Web.config file.

So either in the very begining of your file you have some chars that should not be here , or you XML is just malformed.

Answer 2

Try including runAllManagedModulesForAllRequests="true" for the modules tag inside <system.webServer> tag of your web config file.

An example :

<system.webServer>
<modules runAllManagedModulesForAllRequests="true">
</modules>
</system.webServer>

and if the issue still exists try logging the issue as mentioned in

First, in VS you are using IIS Express, but the second screen shot shows IIS Manager, which means you are deploying the web app to IIS. IIS and IIS Express are different in far too many ways.

Second, the error page shows an error on line -1, which in most cases indicates a missing out-of-band module. Please go to http://iis.net to install them. Examples are, URL Rewrite module, ARR, and so on.

You can use Jexus Manager to verify as it can show more accurate error message than IIS Manager if a configuration error is detected.
