For old Website projects you will need to modify port in solution file  find section similar to below and change  quot VWDPort quot  property Project  quot  E24C65DC-7377-472B-9ABA-BC803B73C61A  quot      quot My Website quot    quot My Website  quot    quot  871AF49A-F0D6-4B10-A80D-652E2411EEF3  quot      ProjectSection WebsiteProperties    preProject         SccProjectName    quot  lt Project Location In Database gt  quot          SccAuxPath    quot  lt Source Control Database gt  quot          SccLocalPath    quot  lt Local Binding Root of Project gt  quot          SccProvider    quot Mercurial Source Control Package quot          TargetFrameworkMoniker    quot  NETFramework Version 3Dv4 7 2 quot          ProjectReferences    quot  41176de9-0c21-4da1-8532-4453c9cbe289  My CommonLibrary dll  f1fda4e5-0233-458e-97b8-381bdb38a777  My Ajax dll  e756176c-9cd1-4dac-9b2d-9162b7554c70  My WEB API Domain dll  7A94A6C8-595B-43CF-9516-48FF4D8B8292  My WEB API Common dll  790654F2-7339-472C-9A79-9E36837571A0  My Api dll  25aa245b-89d9-4d0c-808d-e1817eded876  My WEB API DAL dll  cc43d973-6848-4842-aa13-7751e655966d  My WEB API BLL dll  41591398-b5a7-4207-9972-5bcd693a9552  My FacialRecognition dll  quot          Debug AspNetCompiler VirtualPath    quot  My Website quot          Debug AspNetCompiler PhysicalPath    quot My Website  quot          Debug AspNetCompiler TargetPath    quot PrecompiledWeb My Website  quot          Debug AspNetCompiler Updateable    quot true quot          Debug AspNetCompiler ForceOverwrite    quot true quot          Debug AspNetCompiler FixedNames    quot false quot          Debug AspNetCompiler Debug    quot True quot          Release AspNetCompiler VirtualPath    quot  My Website quot          Release AspNetCompiler PhysicalPath    quot My Website  quot          Release AspNetCompiler TargetPath    quot PrecompiledWeb My Website  quot          Release AspNetCompiler Updateable    quot true quot          Release AspNetCompiler ForceOverwrite    quot true quot          Release AspNetCompiler FixedNames    quot false quot          Release AspNetCompiler Debug    quot False quot          VWDPort    quot 3883 quot          SlnRelativePath    quot My Website  quot      EndProjectSection     ProjectSection ProjectDependencies    postProject          C3A75E14-1354-47CA-8FD6-0CADB80F1652     C3A75E14-1354-47CA-8FD6-0CADB80F1652      EndProjectSection EndProject

I d the same issue on a WCF project on VS2017  When I debug  it gives errors like not able to get meta data  but it turns out the port was used by other process  I got some idea from here  and finally figure out where the port was kept  There are 2 places  1  C    to your solution folder    vs config applicationhost config  Inside  you can find the site that you debug  Under   remove the  that has port issue  2  C    to your project folder      you will see a file with ProjectName csproj user  Remove this file   So  close the solution  remove the  and the user file mentioned above  then reopen the solution  VS will find another suitable port for the site

I m using VS 2019   if your solution has more than one project   class libraries etc  then you may not see the Web tab when clicking on Solution explorer properties   Clicking on the MVC project and then checking properties will reveal the web tab where you can change the port

If you just want to change the port because it is already in use  Follow the following steps   In Visual studio   Right-click on Project Node and Unload Project  Right-click on Project Node and Edit  csproj file  Search for the following tags and remove them     lt DevelopmentServerPort gt 62140 lt  DevelopmentServerPort gt   lt DevelopmentServerVPath gt  lt  DevelopmentServerVPath gt   lt IISUrl gt http   localhost 62116  lt  IISUrl gt      press Ctrl   S to save the document  Right-click on Project Node and load Project   It will work by selecting another port randomly   For further information  please click

Here s a more manual method that works both for Website projects and Web Application projects   you can t change the project URL from within Visual Studio for Website projects    Web Application projects   In Solution Explorer  right-click the project and click Unload Project  Navigate to the IIS Express ApplicationHost config file  By default  this file is located in    userprofile  Documents IISExpress config  In recent Visual Studio versions and Web Application projects  this file is in the solution folder under  Solution Dir   vs config applicationhost config  note the  vs folder is a hidden item  Open the ApplicationHost config file in a text editor  In the  lt sites gt  section  search for your site s name  In the  lt bindings gt  section of your site  you will see an element like this    lt binding protocol  http  bindingInformation    56422 localhost    gt   Change the port number  56422 in the above example  to anything you want  e g     lt binding protocol  http  bindingInformation    44444 localhost    gt   Bonus  You can even bind to a different host name and do cool things like    lt binding protocol  http  bindingInformation    80 mysite dev    gt   and then map mysite dev to 127 0 0 1 in your hosts file  and then open your website from  http   mysite dev  In Solution Explorer  right-click the the project and click Reload Project  In Solution Explorer  right-click the the project and select Properties    Select the Web tab  In the Servers section  under Use Local IIS Web server  in the Project URL box enter a URL to match the hostname and port you entered in the ApplicationHost config file from before  To the right of the Project URL box  click Create Virtual Directory  If you see a success message  then you ve done the steps correctly  In the File menu  click Save Selected Items     Website projects   In Solution Explorer  right-click the project name and then click Remove or Delete  don t worry  this removes the project from your solution  but does not delete the corresponding files on disk  Follow step 2 from above for Web Application projects  In Solution Explorer  right-click the solution  select Add  and then select Existing Web Site     In the Add Existing Web Site dialog box  make sure that the Local IIS tab is selected  Under IIS Express Sites  select the site for which you have changed the port number  then click OK    Now you can access your website from your new hostname port

Deploy your application in the IIS with the default port  Try to debug it using visual studio  It s a good practice  If you use visual studio  it will keep changing the port number most of the time  So better deploy the application in the IIS first and Open the same in visual studio and Debug it

Net Core For those who got here looking for this configuration in  Net core this resides in the lauchSettings json  Just edit the port in the property  quot applicationUrl quot   The file should look something like this       quot iisSettings quot          quot windowsAuthentication quot   false       quot anonymousAuthentication quot   true       quot iisExpress quot            quot applicationUrl quot    quot http   localhost 53950  quot     Here        quot sslPort quot   0               quot profiles quot          quot IIS Express quot            quot commandName quot    quot IISExpress quot          quot launchBrowser quot   true         quot launchUrl quot    quot index html quot          quot environmentVariables quot              quot Hosting Environment quot    quot Development quot                        Or you can use the GUI by double clicking in the  quot Properties quot  of your project  Note  I had to reopen VS to make it work
