Edit and Continue using a Local IIS

debugging, edit-and-continue, iis, visual-studio

Solution

Works in IIS 10.0 (Win 10):

In Administrator command line run

C:\Windows\System32\inetsrv>appcmd set apppool "DefaultAppPool" /+environmentVariables.add[@start,name='COMPLUS_ForceEnC',value='1']

(replace `DefaultAppPool` with app pool name you're using)

This will add tag

    <environmentVariables> 
        <add name="COMPLUS_ForceEnC" value="1" /> 
    </environmentVariables>

into `C:\Windows\System32\inetsrv\config\applicationHost.config` for your app pool, so the app pool process always runs in Edit and Continue mode.

More on the `COMPLUS_ForceEnC` environment variable can be found here.

Problem

Is it possible to have the Edit and Continue option enabled on Visual Studio when debugging using Local IIS instead of IIS express?
