[c#] Changing project port number in Visual Studio 2013

How can I change the project port number in Visual Studio 2013 ?
I'm using ASP.Net and I need to change the port number while debugging in Visual Studio 2013.

To specify a port for the ASP.NET Development Server

• In Solution Explorer, click the name of the application.

• In the Properties pane, click the down-arrow beside Use dynamic ports and select False from the dropdown list.

• This will enable editing of the Port number property.

• In the Properties pane, click the text box beside Port number and
  type in a port number. Click outside of the Properties pane. This
  saves the property settings.

• Each time you run a file-system Web site within Visual Web Developer, the ASP.NET Development Server will listen on the specified port.

Hope this helps.

This has proved to be elusive for me (WebSite Project) until I figured out the following procedure, which combines the solution provided by @Jimmy, with the added step of checking out the solution from Source Control

Steps: (if using VS2013+ with website project and SourceControl)

1. Check out the Solution file only (from sourceControl) (this can be tricky. the easiest way to do this is to make a small change in the Solution file properties/settings and then undo if necessary)
2. Locate the solution file (e.g. solution.sln) in exploer, and open in text editor.
3. Locate the entry: VWDPort = ...... and change to desired port: (example: "60000" - depends on your IISExpress Settings)
4. save the change (will prompt to reload solution)

Steps to resolve this:

1. Open the solution file.
2. Find the Port tag against your project name.
3. Assign any different port as current.
4. Right click on your project and select Property Pages.
5. Click on Start Options tab and checked Start URL: option.
6. Assign the start URL in front of Start URL option like:
   localhost:8080/login.aspx

Well, I simply could not find this (for me) mythical "Use dynamic ports" option. I have post screenshots.

On a more constructive note, I believe that the port numbers are to be found in the solution file AND CRUCIALLY cross referenced against the IIS Express config file

C:\Users\<username>\Documents\IISExpress\config\applicationhost.config

I tried editing the port number in just the solution file but strange things happened. I propose (no time yet) that it needs a consistent edit across both the solution file and the config file.

The Visual Studio Development Server option applies only when you are running (testing) the Web project in Visual Studio. Production Web applications always run under IIS.

To specify the Web server for a Web site project

1. In Solution Explorer, right-click the name of the Web site project for which you want to specify a Web server, and then click Property Pages.
2. In the Property Pages dialog box, click the Start Options tab.
3. Under Server, click Use custom server.
4. In the Base URL box, type the URL that Visual Studio should start when running the current project.
   
   Note: If you specify the URL of a remote server (for example, an IIS Web application on another computer), be sure that the remote server is running at least the .NET Framework version 2.0.

To specify the Web server for a Web application project

1. In Solution Explorer, right-click the name of the Web application project for which you want to specify a Web server, and then click Properties.
2. In the Properties window, click the Web tab.
3. Under Servers, click Use Visual Studio Development Server or Use Local IIS Web server or Use Custom Web server.
4. If you clicked Local IIS Web server or Use Custom Web Server, in the Base URL box, type the URL that Visual Studio should start when running the current project.
   
   Note: If you clicked Use Custom Web Server and specify the URL of a remote server (for example, an IIS Web application on another computer), be sure that the remote server is running at least the .NET Framework version 2.0.

• Open Solution file (.sln) in Editable mode (Notepad or notepad++ or any other tool)
• Find tag name VMDPort and update it to your desired port.

see below snap.

This is the only solution that worked for me after trying several of those above. Switch to your c:\users folder and search for .sln and then remove all .sln files that have your project name. Then restart your computer and rebuild the solution (F5) and it worked!

Right click the web application and select "properties"

There should be a 'Web' tab where http://localhost:XXXXX is specified - change the port number there and this will modify the configuration to use your new port number.

I usually start at 10000 and increment by 1 for each web app, to attempt to steer well clear of other applications and port numbers.
