IIS Locking possibly causing ASP.NET project to throw HTTP Error 500.19

Question

I'm fairly new to .NET framework. I'm trying to run an application copied from another system running visual studio 2010 on my own system. I am also running Visual Studio 2010. When I press F5 to build and run, I get the following error messages

On the output:

------ Build started: Project: cloudintegra.dal, Configuration: Debug Any CPU ------

Also when I select view on browser on a special .aspx file, get the following Internal Server Error

Please how can I resolve this issue?

Answer 1

I guess you are using crystal reports into your project. For that you need to install crystal report runtime.

Check following post, it will resolve your issue. CrystalImageHandler.aspx not found

Answer 2

Again, as stated here check that there isn't any configuration at a parent-level, that causes the conflict.

Based on the error message the <handlers-section can't be accessed. So check any possible parent web.config or even the applicationhost.config located here: D:\Users\Chibuzo\Documents\IISExpress\config\applicationhost.config

The relevant entry should look like this:

<handlers accessPolicy="Read, Script">
