I need to override some code inside of Sitecore.Shell.Applications.Dialogs.ExternalLink.ExternalLinkForm.

I created class based on Sitecore.Shell.Applications.Dialogs.ExternalLink.ExternalLinkForm. Define it at ~/sitecore/shell/Applications/Dialogs/ExternalLink/ExternalLink.xml. but when I try to open External link dialog (click on insert external link at link field) I see an error: 

CodeBeside class "Loreal.Project.Loreal.ExternalLink.LCorpExternalLinkForm, Loreal.Project.Corporate" not found. (method: Sitecore.Web.UI.HtmlControls.CodeBeside.OnInit(EventArgs e)).

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

It is no OnInit Method at based classes.

Any Ideas what I could miss?

    Is the dll that contain the code deployed to your bin folder? Also, can you share the code for the custom implementation

Reset to default

This error generally means that the dll does not contain the namespace defined in 

<CodeBeside Type="Sitecore.Shell.Applications.Dialogs.ExternalLink.ExternalLinkForm,Sitecore.Client"/>

I would check the above parameter in the ExternalLink.xml also check the bin folder for the updated Dll.
