I'm modifying demo application from this article: http://msdn.microsoft.com/en-us/magazine/dd419663.aspx
I need to update all files to use my namespace, for example now file located here:
MySolution\MyApp\DemoApp\ViewModel\MainWindowViewModel.cs
is using such namespace:
namespace DemoApp.ViewModel
{
/// <summary>
/// The ViewModel for the application's main window.
/// </summary>
public class MainWindowViewModel : WorkspaceViewModel
I need to move file here (remove DemoApp folder):
MySolution\MyApp\ViewModel\MainWindowViewModel.cs
and also to use right namespace:
namespace MyApp.ViewModel
{
....
how to do that in visual studio 2010?
Update ok here is possible duplicate Change Project Namespace in Visual Studio Now I know how to change the namespace of the project, but how to move files on the file system? (get rid of "DemoApp" folder)
Go to someplace the namespace is declared in one of your files. Put the cursor on the part of the namespace you want to change, and press F2. This should rename the namespace in every file. At least, it worked in my little demo project I created to test this answer!
Depending on your VS version, the shortcut might also be Ctrl-R,Ctrl-R.
I imagine a simple Replace in Files (Ctrl+Shift+H) will just about do the trick; simply replace namespace DemoApp with namespace MyApp. After that, build the solution and look for compile errors for unknown identifiers. Anything that fully qualified DemoApp will need to be changed to MyApp.
Just right click the solution, go to properties, change "default namespace" under 'Application' section.
Ctrl+Shift+H not the real solution.
You can use Resharper to change your all namespace definitions in your solution. This is the best way I tried before.
https://www.jetbrains.com/resharper/features/code_refactoring.html
You can use CTRL+R, CTRL+R or for complex namespace changes use this tool https://marketplace.visualstudio.com/items?itemName=vs-publisher-599079.FixNamespace
You can use ReSharper for namespace refactoring. It will give 30 days free trial. It will change namespace as per folder structure.
Steps:
Right click on the project/folder/files you want to refactor.
If you have installed ReSharper then you will get an option Refactor->Adjust Namespaces.... So click on this.
It will automatically change the name spaces of all the selected files.
I have gone through the folder structure with a tool called BareGrep to ensure I have got all of the namespace changes. Its a free tool that will allow you to search over the files in a specified file structure.
I tried everything but I found a solution which really works. It creates independed solution with a new namespace name an so on.
In main form find namespace name -> right click -> Refactor -> Rename and select a new name. Check all boxes and click OK.
In the solution explorer rename solution name to a new name.
In the solution explorer rename project name to a new name.
Close VS and rename folder (in total commander for example) in the solution folder to a new name.
In .sln file rename old name to a new name.
Delete old .suo files (hidden)
Start VS and load project
Project -> properties -> change Assembly name and default namespace to a new name.
I know its quite late but for anyone looking to do it from now on, I hope this answer proves of some help. If you have CodeRush Express (free version, and a 'must have') installed, it offers a simple way to change a project wide namespace. You just place your cursor on the namespace that you want to change and it shall display a smart tag (a little blue box) underneath namespace string. You can either click that box or press Ctrl + keys to see the Rename option. Select it and then type in the new name for the project wide namespace, click Apply and select what places in your project you'd want it to change, in the new dialog and OK it. Done! :-)
When I wanted to change namespace and the solution name I did as follows:
1) changed the namespace by selecting it and renaming it and I did the same with solution name
2) clicked on the light bulb and renamed all the instances of old namespace
3) removed all the projects from the solution
4) closed the visual studio
5) renamed all the projects in windows explorer
6) opened visual studio and added all the projects again
7) rename namespaces in all projects in their properties
8) removed bin folder (from all projects)
9) build the project again
That worked for me without any problems and my project had as well source control. All was fine after pushing those changes to the remote.
In asp.net is more to do, to get completely running under another namespace.
Copy your source folder and rename it to your new project name.
Open it and Replace all by Ctrl + H and be sure to include all Replace everything
Press F2 on your Projectname and rename it to your new project name
go to your project properties and adjust it, coz everything has gone and you need to make a new Debug Profile Profile to Create
All dependencies have now an exclamation mark - restart visual studio
Clean your solution and Run it and it should work :)
When renaming a project, it's a simple process
Rename your project
Edit project properties to have new Default Namespace value
Find/Replace all "namespace OLD" and "using OLD" statements in your solution
Manually edit .sln file in text editor and replace your old project name in the directory structure with your new project name.
Reload solution when VS prompts
In VS 2019 you can rename your namespace using the following steps
Place your cursor in the namespace name.
Press Ctrl+. to trigger the Quick Actions and Refactorings menu.
Select Change namespace to .
For more refer to Microsoft documentation
Anyone trying it out on VS Code, Use the typical Rename option, which will update all the namespace usages across, and if the project name is changed, you will have to go inside each .csproj and replace the new project name.
Don't forget to run dotnet restore, then only it will stop showing build issues.
Visual studio 2022 has a new feature Sync Namespace.
You need to right click the project or solution in solution explorer.
If you have C# files which have been moved between folders and the namespaces are out of sync, this feature should come in handy to set the right namespace for each file based on the . format.
This will especially come in handy when you are performing a migration of a legacy code base.

In this project, I created a base repository class for Entity Framework (EfEntityRepositoryBase). Initially it was located in (DataAccess.Concrete). Later i moved it to Core project. My problem here is Visual Studio still sees it in (DataAccess.Concrete) but it is actually in (Core.DataAccess.EntityFramework).
Screenshot below shows solution explorer and pop up showing wrong path.
I tried clean rebuild, manually writing correct path but VS doesn't seem to recognize (Core.DataAccess) exists.
Use the built-in refactoring tools to fix the namespace.
Place your cursor in the namespace name.
Press Ctrl+. to trigger the Quick Actions and Refactorings menu.
Select Change namespace to <folder name>.
Sync namespace and folder name
When the user adds an item (like class, or interface) to the project in Visual Studio, IDE automatically sets default namespace. Each assembly has default namespace, and in case of sub folders within the project, directory structure is reflected in the namespace.
Following structure
Project
Directory1
Subdirectory1
Class
produces following namespace:
namespace Project.Directory1.Subdirectory1
At the beginning everything is clean, and well organized. However later, sometimes we need to move some class to other place. Visual Studio doesn't refactor the namespace after it by default. Is there any option in IDE to turn on? Is there any external tool for it?
Solution without Resharper or NamespaceFixer:
Create new folder named NestedNamespace or whatever you like
Move desired classes to new folder
Enter Ctrl + Shift + H
Under Look in section click three dot button ("Choose search folders")
Add new folder
Under Find what section enter namespace MasterNamespace
Under Replace with section enter namespace MasterNamespace.NestedNamespace
Click Replace All
(Optional) Remove duplicates by replacing MasterNamespace.NestedNamespace.NestedNamespace => MasterNamespace.NestedNamespace
By this way you need to update manually all references outside NestedNamespace, usually by error log.
This is "raw" method, but quite fast and does not require any external programs/add-ons.
I have a few hundred classes, which do not belong to any namespace yet. I would like to select them and put them all into a new namespace. Is there any semi-automated way of doing this in Visual Studio or with the help of a tool like Resharper?
It must work in a way that lets me select the files to put into the namespace, because not all of them should change. Best would be to just select the ones I need in the project and hitting some macro action to add the namespace declaration to the selected files.
Currently I've started opening up the files individually, selecting the class definition and hitting CTRL+K+S to surround with namespace, but this might take a few days.
Simply move the files to a folder that represents the namespace you want, then right click on the folder in Solution Explorer and select Refactor → Adjust Namespaces. ReSharper will prompt you for the files to update, and will then update the namespaces in those files. See the docs on Adjust Namesapces for more details.
I am new to C# and Sharepoint Web Services. I wrote a program awhile back, and I want to use that program as my starting point for the next project. It has all the references and resources already in place. Essentially, I want to copy the solution, and rename it, then change it to meet my current needs.
What's the best way to do that?
Try this:
open Windows Explorer, copy your solution and its folders, paste into a new location.
rename your copied .sln to something else (hit key F2 from Windows Explorer)
open that copied solution, and rename the solution (and perhaps your projects within)
You can open the old project in visual studio and then go to File --> Export Template and follow the wizard.
This will allow you to create a project template that will then be available with all your other project templates in File --> New project.
You can do this per project (or per item which will not help in your case). It then automatically renames your namespaces etc. if the template is configured correctly.
The most straight-forward approach would probably be to just create a new solution, then manually copy all the projects under that solution and add to the new solution (right click on the solution name in Solution Explorer -> Add -> Existing Project.
From there, rename the projects if required, being careful to keep things like the Default namespace and Assembly name consistent with your new project name (you can find these under each project's properties page). Also keep an eye out for any paths that might need changed in the pre / post build steps. You will probably also want to rename the existing namespaces (right-click the namespace in code, Refactor -> Rename...)
Also, this might be a good opportunity to spot which projects will be common to both the old application and your new one, and possibly moving these to a third location from which both solutions can reference them.
I did a bad thing, and I need help undoing it, because I don't know where to make the correction and don't want to further mess things up.
I have an ASP.NET MVC3 solution in VS 2010 with three projects.
In one of the projects, I have three folders, each with several files in them.
I realized that I mistakenly created a file in the wrong folder, so I dragged it into the correct folder.
After I did this, I renamed the namespace by typing in the right one, referencing the folder I just moved it into.
When I did that, the magic cursor, or whatever it's called, appeared under the new text I just typed in...so I hovered. It asked me if I wanted to rename from the old value to the new one I just typed in. So, I click yes.
I think a number of you already know what that means, but I hadn't a clue. Yes, I'm new at this. :)
All using statements in my solution referencing the original folder have been renamed in the process. The original folder is no longer available in any using statements I try to add.
Also of note, I had no clue what was doing this and thought my solution was corrupt or something, so I cleaned, and built, and rebuilt, and rebooted...so undo isn't an option.
What are my options for getting back to "normal" in my solution?
Thanks!
UPDATE, PROBLEM SOLVED:
All I had to do was rename the bad folder so I could create a new folder in the project with the bad folder's original name. I then moved the files from the bad folder into the new folder and corrected their namespaces.
Trashed the old folder.
Updated using statements.
Built the solution.
All is well.
I was afraid the rename went a lot deeper than it did. I'm not certain why this worked, but thank god it did.
Thanks to all who replied. I'll be exploring SVN this evening!
for example, you have tow folders named: Views and ViewModels in your project that named MyMvcProject; your namespaces will be MyMvcProject.Views and MyMvcProject.ViewModels;
and you rename the MyMvcProject.Views to MyMvcProject.ViewModels;
to undo, first exclude the folder named ViewModels - right-click on it, and select Exclude From Project; now open the find and replace window - Ctrl + f - select Quick Replace tab, in Find what textbox type .ViewModels and in Replace with textbox type .Views; set Look in to Current Project and click Replace All;
now must all ViewModels in project - not old viewmodels, because you exclude the ViewModels folder from project - be replaced with Views; now, include the excluded folder (ViewModels) and rebuild the project; if you got an error about namespace of any type, insert this using statement:
using MyMvcProject.Views;
regards.
