I know that It doensn't work. But It's so late to develop another project.

I just want to know how to excute it on Windows 8 and IE 11

whether direct way or indirect way. It's OK.

I'm almost crazy 'cause of this problem.

for a long time I coudn't find any information on searching.

Microsoft said ..

IEHost.dll is the runtime host that provides the ability to host Windows Forms controls and run executables in IE. IEHost is a .Net 1.1 technology that provided a better model than ActiveX to host controls within the browser since they were lightweight and the controls operated under the .NET security model, where they operated inside a sandbox.

For Dev10, the proposal is to remove IEHost.dll for the following reasons

  1. IEHost/HREF-EXEs are surface area exposed to the Internet. This poses a high security risk (we already have bugs filed related to this), and most customers (by far) who install the Framework are getting very little value for this security risk. If IEHost and IEExec is left as-is, a new model needs to be designed where either (a) using this technology is safe and is always on, or (b) is as secure as today and can be configured to be turned off. The cost of doing this is very high.

  2. Customers who want IEHost/HREF-EXE-sytle controls or apps have numerous other technologies they can use, like ClickOnce, XBAP, Silverlight.

  3. Customers who want the exact same functionality as 3.5 SP1 for this feature can continue to use 3.5 SP1. This change, of removing IEHost takes effect only in .Net Framework 4.0.

  4. The opportunity cost and risk of continuing to support this feature for the CLR team is high. Going forward, we will be able to deliver more features and bug fixes that benefit more of our customers if we can remove this from NetFx4.

  • **Solution:** get rid of that horrible abomination and either create a Web Application using Web technology (HTML / CSS / JS) or a Windows Desktop application using WPF, or a Windows 8+ "Metro" Style application using WinRT XAML. winforms is not only completely useless, it is also NOT a Web technology and running winforms stuff inside a Web application is the worst idea in the history of mankind. You cannot seriously expect that it is going to be supported in 2013+ in current OSes and current browsers. – Federico Berasategui Dec 04 '13 at 03:07

I know that your clients won't wait for a full re-write of your website, the show must continue right?, then for now follow these steps to make it work:

Basic steps used in previous versions

  1. In IE add your site to TrustedSites.
  2. Use Caspol.exe to grant full trust to your site.

New steps to use with .Net Framework 4 and IE 11

  1. Re-enable IE host support for IE (Review this post)
  2. Optional: If your site needs to run in compatibility mode add it to "Compatibility View Settings" (Review this post).

Something important to note: This behavior will be the same in any version of Window/IE if you have .Net Framework 4+ installed. i.e. If you have your site running in IE 8/9 and then you install .Net Framework 4 your embedded winforms won't be loaded, you will need to follow the new steps below.

However I completely agree with @HighCore, you must get rid of it, it is a time bomb.
