How to solve Unable to start Debug and xml parsing errror

Unable TO Start Debug Error

Whenever we run asp.net pages in our browser we may get an unable to start debug error

Just we need to udate the registry in the following way it will solve the error

XML Parsing Error: not well-formed

Whenever we access an asp.net page in our browser we may get an xml parsing error that says the XML is not well formed

Fix for ‘XML Parsing Error:

Click Start > Run, and type the following command depending on which ASP.NET framework is in use by the default web site in our IIS.

ASP.NET 3.5 Framework

%Windir%\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -i

ASP.NET 2.0 Framework

%Windir%\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -i

ASP.NET 1.1 Framework

%Windir%\Microsoft.NET\Framework\v1.1.4322\aspnet_regiis.exe -i

You should see a command window that is displayed briefly, that shows that ASP.NET is being installed. After the registration is successful, the window will be closed.

Now refresh the .aspx page that you got the XML Parser error for in the browser and your page should be rendered correctly.

Why did you get this error ?

I have seen this error happen to me in situations where I had installed IIS after the installing the .Net Framework. This make sense. If you install IIS after you install the .Net Framework, then the framework is not registered with IIS. So when a request for a .aspx page comes to IIS, it simply passes on the contents of the page as-is without processing it. So in effect, the browser receives the entire .aspx page’s code, tried to parse it as an XML file, encounters the parsing error at the second character in the page directive and stops.
