I searched already on stackoverflow and on the internet but I couldn't find a similar specific question.
When i have to rename a already checked-in (tfs) project in my visual studio (2010-2013) solution, I always use a procedure similar to this one here in the accepted question:
stackoverflow.com/questions/2043618/proper-way-to-rename-solution-and-directories-in-visual-studio
Here is the important snippet from there (thanks to author):
Close Visual Studio.
Create a backup of your .sln file (you can always roll back).
Imagine you want to rename directory "Project1" to "Project2".
If not using source control, rename the folder from "Project1" to "Project2" using Windows Explorer.
If using source control, rename the folder from "Project1" to "Project2" using the functions supplied by source control. This
preserves the history of the file. For example, with TortoiseSVN,
right click on the file, select TortoiseSVN .. Rename.
In the .sln file, edit all instances of "Project1" to be "Project2".
Restart Visual Studio, and everything will work as before, but with the project in a different directory.
..and there i always do step 6:
Step 6.: In the .sln file, edit all instances of "Project1" to be "Project2".
By observing the .sln file i could see that until step 6 (so in my case of using the tfs i did steps 1,2,3 and 5) there are still occurrences of the old project name in the .sln file:
Project("{XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}") = "Project2",
"Project1\Project2.csproj", "{XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}"
and:
SccProjectUniqueName92 = Project1\Project2.csproj
SccProjectName92 = Project1
SccLocalPath92 = Project1
Until now i had no problems with that approach. But as i could see a colleague of me is skipping step 6 and there are still occurrences of the old project name in the .sln file.
Now i wonder if step 6 is really needed/required?
I am keeping using step 6 just for more cleanness! But whats your opinion on this?
Could the old project name occurrences in the .sln file (if skipping step 6) even some time lead to functional problems with tfs/vs etc.?
Or is it only for the purpose of a cleaner/clearer code better to do carry out step 6?
If you are renaming a project within a solution, that is under source control, really all you need to do is to rename the project in Visual Studio and then submit the changes to the project file and the solution file, back into source control.
Visual Studio and TFS should handle all of the changes for you, VS will rename the project and update the references in the SLN file.
TFS will handle the rename and will maintain the history line.
The only time it should get complicated is if you are moving projects and solutions within source control, when you are carrying out this sort of task then the list above is a fair description of what needs to be done, but after step 4 i would just open the solution remove the project that can no longer be found and add in the newly renamed project, this would then automatically handle the sln file changes. now obviously this would orphan your history on the project if it was under source control, but you would make the project name change through TFS before reopening the solution.
if you want to manually change the sln file then a find and replace operation is the simplest way to update the file.
Coming Back to your question.
You really should ensure the sln file is correct as this tells VS where to download the files from and what projects actually make up the solution, by not updating the sln file correctly you, or other users of TFS may not get the correct files downloaded and you may have issues opening your solution.
An example of fall out from not having these files in line can be found in this question Why missing <SccProjectName> in project file cause "The project file is not bound to source control"
When I try to open my .sln file, Visual Studio quits on me. I can open it by opening up TFS, getting a specific version, choosing the latest version, forcing an overrwrite, opening up the .sln file, and then ignoring an 'incompatible doc message".
However, I would like to know what's wrong and how it can be fixed, in case some day I can't do this.
How can this be fixed?
I would think this is more likely to be the .suo (which is a hidden file). These are know to corrupt (and this has been true since at least VC++ V6). Deleting it will clear all sorts of odd/erroneous behaviour in VS.
(The .suo holds local settings: which files are open and layout, breakpoints, bookmarks, ... only: nothing that really matters to the solution or projects.)
For Visual Studio 2015 and 2017: rather than being in the same location as the solution (.sln) file, it is now held in a, hidden, folder called .vs in the folder containing the solution file.
In Visual Studio 2022, the .suo is in \.vs\MySolution\v17\
Have you tried creating a new sln and importing all the projs? if it doesn't solve the corruption, it may point to a project with a problem.
Get copies of both versions of the file and use your favorite dif tool to see what's changed. sln files are xml (i.e. human readable), so it isn't too hard to figure out what happened.
Difficult to tell. A sln file is quite simple structured, if you open it with a text editor,
check is everything looks all right to you.
Seems to me that the sln file could be in a conflicted state.
My current solution for renaming the project folder is:
Remove the project from the solution.
Rename the folder outside Visual Studio.
Re-add the project to the solution.
Is there a better way?
TFS users: If you are using source control that requires you to warn it before your rename files/folders then look at this answer instead which covers the extra steps required.
To rename a project's folder, file (.*proj) and display name in Visual Studio:
Close the solution.
Rename the folder(s) outside Visual Studio. (Rename in TFS if using source control)
Open the solution, ignoring the warnings (answer "no" if asked to load a project from source control).
Go through all the unavailable projects and...
Open the properties window for the project (highlight the project and press Alt+Enter or F4, or right-click > properties).
Set the property 'File Path' to the new location.
If the property is not editable (as in Visual Studio 2012), then open the .sln file directly in another editor such as Notepad++ and update the paths there instead. (You may need to check-out the solution first in TFS, etc.)
Reload the project - right-click > reload project.
Change the display name of the project, by highlighting it and pressing F2, or right-click > rename.
Note: Other suggested solutions that involve removing and then re-adding the project to the solution will break project references.
If you perform these steps then you might also consider renaming the following to match:
Assembly
Default/Root Namespace
Namespace of existing files (use the refactor tools in Visual Studio or ReSharper's inconsistent namespaces tool)
Also consider modifying the values of the following assembly attributes:
AssemblyProductAttribute
AssemblyDescriptionAttribute
AssemblyTitleAttribute
This is straightforward in Visual Studio 2015 (possibly works in older versions)
In Solution Explorer, right click on Main solution → Rename
In Solution Explorer, right click on project (under solution) → Rename
In Solution Explorer, double click, or right click on Properties → goto Application Tab, rename Assembly name and Default namespace to match.
If you wish to also rename the namespace, open one of your class files. Right click the namespace → Rename.... This should search and replace all references to your namespace throughout the project.
Close the project → rename the project folder.
Edit the .sln file in Notepad, and change the path to the csproj, i.e., fu\bar.csproj → bar\bar.csproj.
There is another way doing this, using the *.sol, *csproj files.
Open your solution file.
Search for the *.csproj you would like to change.
It will be like this (relative to the *.sol file):
Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}") = "Shani.Commands.Impl", "Shani.Commands.Impl\Shani.Commands.Impl.csproj", "{747CFA4B-FC83-419A-858E-5E2DE2B948EE}"
And just change the first part to the new diretory for example:
Impl\Shani.Commands.Impl\Shani.Commands.Impl.csproj
Of course, don't forget to move the whole project to that directory.
Man, have I struggled with this. Unfortunately there isn't a one click solution in Visual Studio, but if you're running Visual Studio 2012 and your project is under source control with Team Foundation Server, here is how I got it to work, while keeping the source history:
(Make sure you read #mjv's comment below, as he notes that you can skip step 5-10)
Make sure you have checked in all changes, so you have no pending changes.
Remove the project from the solution, by right clicking and selecting Remove.
Now, in Windows Explorer, rename the project folder.
Go back to Visual Studio, and in Solution Explorer, right click the solution and choose Add -> Existing project. Select the project file for the project you removed in step 2, which should be located in the renamed folder.
Now the project is back in the solution, but the project doesn't seem to be added to source control. To fix that, open Source Control Explorer.
Find the project folder in Source Control Explorer, that corresponds with the project folder on your disk, that you renamed in step 3.
Rename the folder in Source Control Explorer, so it has the same name as the project folder on disk.
Now take a look at your pending changes. You should have changes to the solution file and a rename operation on the project folder.
Do a rebuild and make sure everything compiles correctly. If you had inter-project references to the project you renamed, you need to add them again to the individual projects that referenced it.
You should be all set now. Go and check everything in.
The above guide worked for me. If it doesn't work for you, try and delete your local solution completely, and remove the folder mapping in your workspace. Restart Visual Studio just in case. Make sure you actually deleted the whole solution from your computer. Now readd the solution mapping to your workspace and get the latest version. Now try the above steps. The same applies if something goes wrong while following the above steps. Just delete your solution locally and get the latest source, and you'll have a clean slate to work with.
If you're still having problems, make sure that you haven't changed anything manually in the solution file, or trying other 'tricks' before trying the above steps. If you have changed something and checked it in, you might want to consider doing a rollback to the point just before you started messing with the renaming of the project.
Of course, you'd also want to rename the project itself, in Solution Explorer. You can do this before the steps above, but in that case, make sure you check in that change before applying the steps above. You can also do it afterwards, but make sure you follow all the steps above first, and check in your changes before trying to rename the project name in Solution Explorer. I don't recommend trying to mix the above steps with a rename of the project name in Solution Explorer. It might work though, but I would recommand doing it in 2 separate changesets.
Currently, no. Well, actually you can click the broken project node and in the properties pane look for the property 'Path', click the small browse icon, and select the new path.
Voilà :)
The simpler solution is the following:
Right-click the project and rename it.
(optional) Open the project’s property settings and modify the assembly name (and optionally the default namespace) to use the new project name.
(optional) Select the namespace name in a source file, right click and select Refactor/Rename to globally rename the namespace to the new project name.
(optional) Open the AssemblyInfo.cs file and change the assembly name to match.
Save and close the solution.
Using Windows Explorer, rename the project folder to the new name.
Open the SLN file in a text editor and find the one reference to the project path and change it to use the new folder name.
There are four needed steps, but seven recommended. At the end of the day though the project is renamed completely. Technically, the folder name for the project doesn’t have to match the project itself, so even that step is optional, but it can be confusing if they don’t match. The same for the assembly and namespace names.
In andersjanmyr's answer it's easier to rename the project first.
Rename the project.
Close the solution (save it).
Rename the folders outside Visual Studio.
Open the solution, ignoring the warnings.
Go through all unavailable projects and set the property 'File Path' to the new location of your project file, i.e. someproject.csproj.
Reload the project.
Also, after those steps are carried out, you might want to rename other references to your old project name.
In project properties, update the Assembly Name and Default Namespace.
This will update the following in the project file...
<RootNamespace>SomeProjectName</RootNamespace>
<AssemblyName>SomeProjectName</AssemblyName>
...and will get rid of the error "Namespace does not correspond to file location, should be: 'SomeProjectName'"
Rename your root namespace (if you have ReSharper right click the Namespace and go Refactor -> Rename).
Change all occurrences of your old project name in AssemblyInfo.cs.
For those using Visual Studio + Git and wanting to keep the file history (works renaming both projects and/or solutions):
Close Visual Studio
In the .gitignore file, duplicate all ignore paths of the project you want to rename with renamed versions of those paths.
Use the Git move command like this:
git mv <old_folder_name> <new_folder_name>
See documentation for additional options: https://git-scm.com/docs/git-mv
In your .sln file: Find the line defining your project and change the folder name in path. The line should look something like:
Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}") = "<Project name>", "<path-to-project>\<project>.csproj"
Open Visual Studio, and right click on project → Rename
Afterwards, rename the namespaces.
I read that ReSharper has some options for this. But simple find/replace did the job for me.
Remove old .gitignore paths.
For Visual Studio 2017 you can use my Visual Studio extension:
Download
It will rename the project in:
The project location folder
The solution file
References in other projects
The assembly name, information
The default namespace
I just had to do this myself (using Visual Studio 2010). As some folks have answered, the simplest step seems to be:
Close the Visual Studio project.
Open the .sln file and rename the project directory prefix for each of the .csproj occurrences.
Save the .sln file
Rename the actual project folder directory on your hard drive to match your changes in the .sln file.
Open the .sln (in Visual Studio) and rebuild
Using Visual Studio 2019, I followed below steps to make the project name change successful:
Close the solution
Rename the project folder to match with new project name
Open solution file in notepad++ kind of editor and edit the FilePath with new project name folder
Open the solution and click No if it ask whether you want to open from source control
Right click the project which you want renaming and click Properties then change below:
Change Assembly Name,
Default Assembly namespace and
Assembly information with new name
Open any of the file and move the file to new namespace which will be done by all files
If you have app.config kind of files then make sure to move them also in new namespace
Rebuild it which will work successfully
A proven solution for Visual Studio extension for Data Tools for Business Intelligence (SSDT-BI 2013):
Move the Project folder to its new location (don't rename anything yet)
In Solution Explorer, rename the Project / Solution.
Close (and save) the newly-renamed project.
Rename the project's folder and .sln file.
Use a text editor and open the newly-renamed project solution file (.sln) (I used Notepad++)
In line number 6 you'll see: "Project {fdjfksdjk4387!...} = "OLDPROJECT", "OLDFOLDER\OLDPROJECT.rptproj". Rename everything with the new names used in step 4. (i.e. ... = "NEWPROJECT", "NEWFOLDER\NEWPROJECT.rptproj"... )
That's it!
It was tested 100% and worked flawlessly in my case.
NOTE: I can't confirm if it works under different project templates and other Visual Studio versions. As always, do backup everything beforehand.
What worked for me in Visual Studio 2017:
Close solution in Visual Studio
Rename the directories of projects in the solution.
(push change in source control - Git in my case)
Edit the .sln file in a text editor (outside Visual Studio 2017) changing the name of the directory.
Reopen the solution in Visual Studio
It said something like "re-adding project". I rebuilt everything and everything was good to go.
See item 3 in the linked article.
Close the solution and the IDE.
In Windows Explorer: Change the directory name to the new name.
In Windows Explorer: Open the .sln file with a text editor.
Change the directory name to the new name and save.
Restart the IDE and open the solution from menu File → Recent Files menu if it doesn't start automatically.
Click on the project folder in Solution Explorer and check the path property in the properties at the bottom. It will now be referencing to the new project folder.
It worked for me.
I've had to do this lots of times. It's really useful to be able to repurpose an existing project, but be able to rename text in namespaces, files, and folders (including file / directory names).
Using a recursive find and replace starting at the root folder means the rename doesn't break links to projects in the solution files and project references.
To this end, I have created a project to do just this. The application also makes an effort to ignore version control folders such as .git, .svn and the .vs settings file. More information is in the README.

I am recently working on .Net 6 project with VS2022. and I need to rename my templatemicroservice to my UserMicroservice.
.Net 6 changes most of the things for you. like AssemblyNames and NameSpaces. Also, it changes the ProjectName references in .sln automatically. So, this answer will really help you to rename your service with no hurdles.
So, Steps I followed:
Open the solution in Visual Studio and did these steps:
I renamed my solution by right clicking on it. like, TemplateServiceSolution to UserServiceSolution.
Renamed all the Projects in solution by right clicking on them. like, TemplateService to UserService.
In a specific project, I searched the namespaces like: namespace TemplateService and replaced all by namespace UserService. Do this step in each project. Also relplace using TemplateService to using UserService.
Open your launchsettings.json, and rename anything related to old service, as I had few things in profiles of launchsettings.json.
Just to be sure, please check your startup and program.cs files as well, I didn't have any changes in them.
Closed the solution from Visual Studio and did these steps:
Closed the solution, and opened the File Explorer. Renamed all my project folders from TemplateService to UserService.
Open the .sln in notepad/notepad++, and must change the Folder Structure name. like for a particular project, I should give the correct .csproj paths. as shown in image, I need to rename TemplateService to UserService.
Open the solution in Visual Studio. Most of your Dependencies will be loaded as soon as you Load your solution in Visual Studio Code. and you are ready.
I just solved this problem for myself writing a global dotnet tool (that also takes into account git+history).
Install via
dotnet tool install -g ModernRonin.ProjectRenamer, use with renameproject <oldName> <newName>.

This worked well for me in Visual Studio 2019.
Rename the solution, projects in Visual Studio by simply single
clicking on the file names as normal.
Rename the namespaces in Visual Studio.
Rename the desired elements on the main project page (publish location, application, default namespace, whatever). As noted correctly, this does nothing for the folders, but it does rename the project files and keeps everything tied together in Visual Studio.
Close Visual Studio.
Rename the folders.
Open Visual Studio and reply 'no' to getting projects from Source Control.
Delete the unloaded project references.
Add each project back in using Add existing project from Solution. This tied everything together and the project built for me.
Please comment on and correct anything above that does not work.
This is how I renamed my existing project in VS19.
Close the visual studio project
Rename and open the each project folder name on your drive
Rename each .csproj
Open .sln file and rename the project directory prefix for each of the .csproj occurrences.
Open the .sln file in visual studio and rebuild
Update prevoius nameSpace refrence with new one by going through each file or using ReplaceAll
Note: This fix is for Visual Studio 2008, but it should work here.
Using Windows Explorer, rename both the solution folders (the parent folder and the child folder) to the new solution name.
Delete the .sln file located in the parent folder.
In Visual Studio, select menu File ► Open Project.
Drill into the new folder you just renamed and open the .csproj file (located in the child folder).
Right-click the project name and rename it to what you want. (It should be the same name as the folder in step 1.)
Select menu File ► Close Solution. A dialog will ask if you want to save changes to the .sln file. Click Yes.
In the Save File As dialog, point to the newly renamed parent folder and click Save.
(Note: Make sure the .sln file has the same name as the folder. It is not required, but it maintains consistency.)
Done.
I have written a small tool that automates all these steps. It also supports Subversion for now.
Information about current releases can be found at Visual Studio Project Renamer Infos.
The latest releases can now be downloaded from the Visual Studio Project Renamer Download Page.
Feedback is much appreciated.
I often had the same problem of renaming a project in Visual Studio and editing the folder name, project name, and .sln file in order to accomplish that. I just wrote a VBScript script that accomplishes all that. You have to be careful with the strings you choose for replacing.
You just have to put the .vbs file in the same directory as the .sln file of the solution.
' Script parameters'
Solution = "Rename_Visual_Studio_Project" '.sln'
Project = "Rename_Visual_Studio_Project" '.csproj'
NewProject = "SUCCESS"
Const ForReading = 1
Const ForWriting = 2
Set objFso = CreateObject("Scripting.FileSystemObject")
scriptDirr = objFso.GetParentFolderName(wscript.ScriptFullName)
' Rename the all project references in the .sln file'
Set objFile = objFso.OpenTextFile(scriptDirr + "\" + Solution + ".sln", ForReading)
fileText = objFile.ReadAll
newFileText = Replace(fileText, Project, NewProject)
Set objFile = objFSO.OpenTextFile(scriptDirr + "\" + Solution + ".sln", ForWriting)
objFile.WriteLine(newFileText)
objFile.Close
' Rename the .csproj file'
objFso.MoveFile scriptDirr + "\" + Project + "\" + Project + ".csproj", scriptDirr + "\" + Project + "\" + NewProject + ".csproj"
' Rename the folder of the .csproj file'
objFso.MoveFolder scriptDirr + "\" + Project, scriptDirr + "\" + NewProject
Rename the project in the solution and the project folder
Delete the project from the solution
Add the existing project to the solution (your renamed project)
It works for me. TFS will also track the new project.
You cannot rename a folder if your project is currently running
Stop your application Shift+F5
Rename your folder from the Solution Explorer (right-click > rename or F2)
When using TFS, step 2 is actually to rename the folder in source control and then get the latest before reopening the solution.
There's a simpler approach which was tested in Visual Studio 2013 Update 1 and applicable for TFS-connected projects:
Open Visual Studio, but let the solution be closed.
Open Source Explorer and rename the desired folder (the solution will be closed for you if you didn't already close it first).
Right-click on the solution (from Source Explorer also) and select check-in.
Open the solution. You'll be told that there're new projects added. Accept to get the changes.
Remove the project from the solution and add it again, and then check-in.
Check that the internal references are OK.
We recently uploaded a beta of a free Visual Studio extension which does this stuff for you.
Have a look at Visual Studio Gallery: Gallery Download
Well, I did it my way
Close Visual Studio 2012
Rename your subdirectory to the preferred name under .sln
Delete the *.suo file
Open the solution again, and fix any properties of Project(s) loaded to meet the new subdirectory name
Rename the project outside Visual Studio.
Edit your_project_name.sln with a text editor, and rename the path to the new path.
Open .sln in a text editor, and in the following line change <FolderName> to your new folder name
Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}") = "Ricky", "\.csproj", "{021CC6B0-8CFB-4194-A103-C19AF869D965}"
