ASP.Net Edit and Continue in Visual Studio 2005/2008

I have seen many articles that said Edit and Continue does not work in ASP.Net for Visual Studio 2005. Well, it works for me and here is how to enable it. I have showed many people how to enable this and every time I show someone I have to figure it out again. So I am putting this out there to hopefully save someone else the frustration.

To enable Edit and Continue there are 2 separate setting. The first is under Tools.. Options. Open the Debug section of the tree and click on the Edit and Continue Group. Make sure “Enable Edit and Continue” is checked. If you are using the VS 2005 Professional you may need to click a checkbox at the bottom of this screen saying something like Show all Options.

The second setting is in a strange place. I am not sure if this works with the new Web Projects introduced in 2005. We are using the Visual Studio 2005 Web Application Project which may have something to do with it. Open up the solution you are attempting to debug, right click on the web project, and click Properties. When the property window opens click down to the “Web”. Check the Enable Edit and Continue box and you should be all set.

I will never understand why there are two places you have to enable this, but at least it works.

UPDATE: You must be at a break point in your code to edit. You cannot edit method signatures, add new methods, etc. Changes like that were not what Edit and Continue were designed for and I can’t even start to think how that would be implemented by Microsoft.

UPDATE (again): I recently started working with Visual Studio 2008. This fix applies to that version as well.
