Simple Asp .Net Application, error : Server Error in '/' Application - asp.net

Server Error in '/' Application.
The resource cannot be found.
Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable.

Configuration: .Net framework 3.5, windows 10 operating system [IIS express 10]
How can I solve this Problem, Please help me

Hosting server will typically generate a "404 Not Found" web page when a user attempts to follow a broken or dead link.
Check the URL and look for resource (webpage/service/view) does exist?

This means that the url you tried to access doesnt exist, or the IIS is not running, are you sure you ran it from visual studio using F5 ?

The resource cannot be found in IIS server 2012

I am trying to move a web site, with several web applications over to a new server running server 2012. The application was written in .net 3.5. I have been struggling through some issues but am now stuck on The resource cannot be found
Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.
Requested URL: Any web app I tried URLs
Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.6.1087.0
I have tried running the app pool as .net 2.0. Enabled 32-bit applications. Set the security of the entire inetpub folder to allow all users full permission, still I am stuck. I also tried setting the application pool back to the default user. I get a 500 error then. The user I am running the app pool under is in the IIS_* group. The application pool is setup identical to that of the old server. The file does exist at the url I am trying and it is named correctly as I have tried it on several different applications within the site. It appears this is .net to blame more than IIS. Due to enterprise security I can't get remote debugging enabled on the server. Is there any logging that I can check to see why the page won't load?

HTTP Error 500.19 - Internal Server Error - what is the cause?

I have created an Angular2/.NETCore application in Visual Studio, which when debugged works fine. I published this on my local IIS, and this also is running fine. However when I moved everything to a remote server, I got the following error:-
HTTP Error 500.19 - Internal Server Error
Detailed Error Information:
Module IIS Web Core
Notification Unknown
Handler Not yet determined
Error Code 0x8007000d
Config Error
I checked that I have the correct permissions on the remote IIS, however I cannot understand why I am getting this error.
I already tried the following link
but no luck so far.
Anyone has any idea what the problem might be?
Thanks for your help and time.
Install the .NET Core Windows Server Hosting bundle on the hosting system. The bundle will install the .NET Core Runtime, .NET Core Library, and the ASP.NET Core Module.

Unable to run empty ASP.Net MVC 3 Application

I have installed:
Visual Web Developer 2010 Express
ASP.Net MVC 3
I went to File > New Project > ASP.Net MVC 3 Web Application
I chose Empty template with ASPX view engine. VWD generated lots of files.
When I clicked Run, I get the following error:
Server Error in '/' Application.
The resource cannot be found.
Description: HTTP 404. The resource you are looking for (or one of its

Version Information: Microsoft .NET Framework Version:4.0.30319;
ASP.NET Version:4.0.30319.1
What am I missing here? Is there something else that needs to be done to get it running?
Yes, that's true
An empty application doesn't have a single controller or view defined. It's all on you. Most people start with an application.

visual studio asp.net mvc, changing target framework

Hello there Im have just changed the target framework for an asp.net mvc project from target framework 4 t 3.5, I keep getting this error when I try to debug, or go to any controller action
'HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly. '
Any ideas why I keep getting this error? as soon as I revert back to .net 4.0, everything is fine
ps could be an issue with routing as the global.asax Application_Start() is not not hit hence route entries are not registered
Thanks
Are you running the site on IIS or Casini? If IIS, you should also check that the Application pool is targeting .NET Runtime 2.0
