Changing project port number in Visual Studio 2013

Question

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.

Answer 1

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.

There are two project types in VS for ASP.NET projects:

Web Application Projects (which notably have a .csproj or .vbproj file to store these settings) have a Properties node under the project. On the Web tab, you can configure the Project URL (assuming IIS Express or IIS) to use whatever port you want, and just click the Create Virtual Directory button. These settings are saved to the project file:

<ProjectExtensions>
  <VisualStudio>
    <FlavorProperties GUID="{349c5851-65df-11da-9384-00065b846f21}">
      <WebProjectProperties>
       <DevelopmentServerPort>10531</DevelopmentServerPort>
       ...
     </WebProjectProperties>
    </FlavorProperties>
  </VisualStudio>
</ProjectExtensions>

Web Site Projects are different. They don't have a .*proj file to store settings in; instead, the settings are set in the solution file. In VS2013, the settings look something like this:

Project("{E24C65DC-7377-472B-9ABA-BC803B73C61A}") = "WebSite1(1)", "http://localhost:10528", "{401397AC-86F6-4661-A71B-67B4F8A3A92F}"
    ProjectSection(WebsiteProperties) = preProject
        UseIISExpress = "true"
        TargetFrameworkMoniker = ".NETFramework,Version%3Dv4.5"
        ...
        SlnRelativePath = "..\..\WebSites\WebSite1\"
        DefaultWebSiteLanguage = "Visual Basic"
    EndProjectSection
EndProject

Because the project is identified by the URL (including port), there isn't a way in the VS UI to change this. You should be able to modify the solution file though, and it should work.
