Step 1: Select the âTools->External Toolsâ menu option in VS or Visual Web Developer. This will allow you to configure and add new menu items to your Tools menu.
Step 2: Click the âAddâ button to add a new external tool menu item. Name it âWebServer on Port 8010â (or anything else you want).
Step 3: For the âCommandâ textbox setting enter this value: C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\WebD ev.WebServer.EXE (note: this points to the web-server that VS usually automatically runs).
Step 4: For the âArgumentsâ textbox setting enter this value: /port:8010 /path:$(ProjectDir) (or any port you like)
Step 5: Select the âUse Output Windowâ checkbox (this will prevent the command-shell window from popping up.
Once you hit apply and ok you will now have a new menu item in your âToolsâ menu called âWebServer on Port 8010â. You can now select any web project in your solution and then choose this menu option to launch a web-server that has a root site on port 8010 (or whatever other port you want) for the project.
You can then connect to this site in a browser by simply saying http://localhost:8010/
. All root based references will work fine.
Step 6: The last step is to configure your web project to automatically reference this web-server when you run or debug a site instead of launching the built-in web-server itself. To-do this, select your web-project in the solution explorer, right click and select âproperty pagesâ. Select the âstart optionsâ setting on the left, and under server change the radio button value from the default (which is use built-in webserver) to instead be âUse custom serverâ. Then set the Base URL value to be: http://localhost:8010/
Obviously I don't know if this is the problem you had but definitely it is something similar, essentially the problem should be that the same port used by your Development Server is not available because it is already used by another web server.
