Exception Error executing child request for handler 'System.Web.Mvc.HttpHandlerUtil+ServerExecuteHttpHandlerWrapper'.

[dbloch3643]

I'm using MvcSiteMap 5.0 Core. On two pages that I'm generating text/excel files on, I get the exception "Error executing child request for handler 'System.Web.Mvc.HttpHandlerUtil+ServerExecuteHttpHandlerWrapper'." When the file is ready to be downloaded. I have Googled the error and found that sometimes ThreadAbortException is thrown so I have caught that in the try/catch block. I can't find much more on this exception. Any help would be great.

Some images of my code and such.

This may not be related to your issue, but a couple of problems I spotted are:

1. You are using the old (v3) schema to set up your .sitemap file.
2. You have installed the core package, which doesn't deploy any of the display templates, schema file, or other web features into your project.

The MvcSiteMapProvider.MVC5.Core package is meant for adding a reference to class library projects so they can implement interfaces of MvcSiteMapProvider, but it doesn't deploy any of the MVC support (registering namespaces, deploying display templates, deploying the schema file for the XML, deploying the default Mvc.sitemap file, etc).

First of all, copy just the nodes out of your .sitemap file and put them somewhere else as a backup. Delete the .sitemap file. Then install the MvcSiteMapProvider.MVC5 package. Copy the nodes back into the new Mvc.sitemap file.

Did this solution work for you?

[dbloch3643]

NightOwl888, sorry for the late reply.

Though I only have the Core installed I manually installed the templates and such to get my menu to work. I figured out that I need to remove the Response.Flush and Response.End in order to get rid of the error message. Earlier posts I read and the .Flush and .End were wrong.

[NightOwl888]

Okay, so it sounds like you got it working...

There's nothing wrong with installing the templates and such manually. And as long as you are using Razor only, you might be able to get away without the Razor web.config sections (although intellisense won't work for @Html.SiteMap().Menu(), etc). All of the MvcSiteMapProvider_ appSettings are optional and the defaults are reasonable for most cases (do note that you will need to manually enable support for MvcSiteMapNodeAttribute if you want to use it).

However, if you are using the /sitemap.xml endpoint there is one section that is required for MVC 4 and MVC 5 as described in #289.

You might also want to review the install.ps1 and web.config.transform files and use them as a guide in copying the settings out of a new project with MvcSiteMapProvider.Web installed into yours.
