How to fully clean bin and obj folders within Visual Studio

Question

If you right click on a folder  you will see a  Clean  menu item  I assumed this would clean  remove  the obj and bin directory  However  as far as I can see  it does nothing   Is there another way   please don t tell me to go to Windows Explorer or the cmd exe  I d like to remove the obj and bin folder so that I can easily zip the whole thing

this answer is great I just want to comment on the last part of the answer  NOTE   You should have this stored in a PowerShell file and place that file at the root of your solution  where the  sln file resides   and then run it when you want a proper clean  not the micky mouse one that VisualStudio does  and reports success too    Alternatively  you can add the following to your profile ps1 function CleanSolution       Get-ChildItem -inc bin obj -rec   Remove-Item -rec -force    Set-Alias cs CleanSolution   Then you can use either CleanSolution or cs to run  That way you can use it for any project and without the    prefix of the filename

This site  https   sachabarbs wordpress com 2014 10 24 powershell-to-clean-visual-studio-binobj-folders  uses William Kempf s powershell commands to remove any bin and obj folders from the current directory and sub directories  It should be possible to run it from the root of the drive   Here is William s version   gci -inc bin obj -rec   rm -rec -force   In William s own words      That wipes out all of the    bin    and    obj    directories in the current   directory and every subdirectory  Super useful to run in your   workspace directory to get to a    clean    state  especially when someone   messes up and there   s something that a Clean or Rebuild inside the IDE   doesn   t catch       For those of you reading that may not know  PowerShell supports   command aliases  here it is rewritten again not using the aliases  Get-ChildItem -inc bin obj -rec   Remove-Item -rec -force       NOTE   You should have this stored in a PowerShell file and place that   file at the root of your solution  where the  sln file resides   and   then run it when you want a proper clean  not the micky mouse one that   VisualStudio does  and reports success too

For Visual Studio 2015 the MSBuild variables have changed a bit        lt Target Name  SpicNSpan  AfterTargets  Clean  gt   lt  -- common vars https   msdn microsoft com en-us library c02as0cs aspx f 255 amp MSPPError -2147217396 -- gt            lt RemoveDir Directories    TargetDir     gt   lt  -- bin -- gt            lt RemoveDir Directories    SolutionDir  vs    gt   lt  --  vs -- gt            lt RemoveDir Directories    ProjectDir   BaseIntermediateOutputPath     gt   lt  -- obj -- gt     lt  Target gt    Notice that this snippet also wipes out the  vs folder from the root directory of your solution  You may want to comment out the associated line if you feel that removing the  vs folder is an overkill  I have it enabled because I noticed that in some third party projects it causes issues when files ala application config exist inside the  vs folder   Addendum   If you are into optimizing the maintainability of your solutions you might want to take things one step further and place the above snippet into a separate file like so      lt Project xmlns  http   schemas microsoft com developer msbuild 2003  gt          lt Target Name  SpicNSpan  AfterTargets  Clean  gt   lt  -- common vars https   msdn microsoft com en-us library c02as0cs aspx f 255 amp MSPPError -2147217396 -- gt               lt RemoveDir Directories    TargetDir     gt   lt  -- bin -- gt               lt RemoveDir Directories    SolutionDir  vs    gt   lt  --  vs -- gt               lt RemoveDir Directories    ProjectDir   BaseIntermediateOutputPath     gt   lt  -- obj -- gt          lt  Target gt     lt  Project gt    And then include this file at the very end of each and every one of your   csproj files like so                    lt Import Project        Tools ExtraCleanup targets   gt     lt  Project gt    This way you can enrich or fine-tune your extra-cleanup-logic centrally  in one place without going through the pains of manually editing each and every   csproj file by hand every time you want to make an improvement

I can t add a comment yet  no minimal reputation reached  so I leave this reply to underline that   the  BeforeBuild  action with   lt RemoveDir Directories    BaseIntermediateOutputPath     gt  is great but  for me  is conflicting with an Entity Framework model included into the same project   The error I receive is     Error reading resource   mymodel  csdl  --  Could not find a part of the path   myprojectpath  obj Release edmxResourcesToEmbed  mymodel  csdl   I suppose  the  edmxResourcesToembed  is created before the  BeforeBuild  target action is executed

As others have responded already Clean will remove all artifacts that are generated by the build   But it will leave behind everything else   If you have some customizations in your MSBuild project this could spell trouble and leave behind stuff you would think it should have deleted   You can circumvent this problem with a simple change to your   proj by adding this somewhere near the end       lt Target Name  SpicNSpan          AfterTargets  Clean  gt       lt RemoveDir Directories    OUTDIR    gt   lt  Target gt    Which will remove everything in your bin folder of the current platform configuration   ------ Edit Slight evolution based on Shaman s answer below  share the votes and give him some too    lt Target Name  SpicNSpan   AfterTargets  Clean  gt       lt  -- Remove obj folder -- gt       lt RemoveDir Directories    BaseIntermediateOutputPath     gt       lt  -- Remove bin folder -- gt       lt RemoveDir Directories    BaseOutputPath     gt   lt  Target gt    ---- Edit again with parts from xDisruptor but I removed the  vs deletion as this would be better served in a  gitignore  or equivalent   Updated for VS 2015    lt Target Name  SpicNSpan  AfterTargets  Clean  gt   lt  -- common vars https   msdn microsoft com en-us library c02as0cs aspx f 255 amp MSPPError -2147217396 -- gt        lt RemoveDir Directories    TargetDir     gt   lt  -- bin -- gt        lt RemoveDir Directories    ProjectDir   BaseIntermediateOutputPath     gt   lt  -- obj -- gt   lt  Target gt    He also provides a good suggestion on making the task easier to deploy and maintain if you have multiple projects to push this into   If you vote this answer be sure to vote them both as well

I use VisualStudioClean which is easy to understand and predictable  Knowing how it works and what files it is going to delete relieves me   Previously I tried VSClean  note VisualStudioClean is not VSClean   VSClean is more advanced  it has many configurations that sometimes makes me wondering what files it is going to delete  One mis-configuration will result in lose of my source codes  Testing how the configuration will work need backing up all my projects which take a lot of times  so in the end I choose VisualStudioClean instead   Conclusion   VisualStudioClean if you want basic cleaning  VSClean for more complex scenario

Clean will remove all intermediate and final files created by the build process  such as  obj files and  exe or  dll files   It does not  however  remove the directories where those files get built  I don t see a compelling reason why you need the directories to be removed  Can you explain further   If you look inside these directories before and after a  Clean   you should see your compiled output get cleaned up

Just an addendum to all the fine answers above in case someone doesn t realize how easy it is in VB C  to automate the entire process down to the zip archive    So you just grab a simple Forms app from the templates  if you don t already have a housekeeping app  and add a button to it and then ClickOnce install it to your desktop without worrying about special settings or much of anything  This is all the code you need to attach to the button   Imports System IO Compression  Private Sub btnArchive Click sender As Object  e As EventArgs  Handles btnArchive Click     Dim src As String    C  Project      Dim dest As String   Path Combine  D  Archive    Stub   amp  Now ToString  yyyyMMddHHmmss    amp    zip       If IsProjectOpen   Then  You don t want Visual Studio holding a lock on anything while you re deleting folders         MsgBox  Close projects first   expletive deleted    vbOKOnly          Exit Sub     End If     If MsgBox  Are you sure you want to delete bin and obj folders    vbOKCancel    DialogResult Cancel Then Exit Sub     If ClearBinAndObj src  Then ZipFile CreateFromDirectory src  dest  End Sub  Public Function ClearBinAndObj targetDir As String  As Boolean     Dim dirstodelete As New List Of String      For Each d As String In My Computer FileSystem GetDirectories targetDir  FileIO SearchOption SearchAllSubDirectories   bin           dirstodelete Add d      Next     For Each d As String In My Computer FileSystem GetDirectories targetDir  FileIO SearchOption SearchAllSubDirectories   obj           dirstodelete Add d      Next     For Each d In dirstodelete         Try             Directory Delete d  True          Catch ex As Exception             If MsgBox  Error     amp  ex Message  amp    - OK to continue    vbOKCancel    MsgBoxResult Cancel Then Return False         End Try     Next     Return True End Function  Public Function IsProjectOpen       For Each clsProcess As Process In Process GetProcesses           If clsProcess ProcessName Equals  devenv   Then Return True     Next     Return False End Function   One thing to remember is that file system deletes can go wrong easily  One of my favorites was when I realized that I couldn t delete a folder because it contained items created by Visual Studio while running with elevated privileges  so that I could debug a service     I needed to manually give permission or  I suppose  run the app with elevated privileges also  Either way  I think there is some value in using an interactive GUI-based approach over a script  specially since this is likely something that is done at the end of a long day and you don t want to find out later that your backup doesn t actually exist
