Edit and Continue using a Local IIS

Question

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

Answer 1

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 run in Edit and Continue mode.

More on the COMPLUS_ForceEnC environment variable can be found here.

Answer 2

Based on Ondrej answer, here is a simple code to enable edit-and-continue on all your application-pools in one click:

SET "APPCMD=%systemroot%\system32\inetsrv\AppCmd.exe"
FOR /F "TOKENS=*" %%f IN ('%APPCMD% list apppool /text:name') DO %APPCMD% set apppool "%%~f" /+environmentVariables.add[@start,name='COMPLUS_ForceEnC',value='1']
PAUSE

save this code as "Enable Edit And Continue.bat" and run it (right click on the file and choose "Run as Administrator").

Enjoy!
