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.

I'm working on a winform app.
The design view worked well until I renamed the Form1.cs to FormMain.cs.
The program itself is ok. It can be compiled with no error and it runs well(with right form). But visual studio keep warning me that there are mistakes in FormMain.cs. It seems that FormMain class in FormMain.Designer.cs is totally ignore as it alerts "InitializeComponent(); is not defined."
And the design view goes blank as if the form was just newly-created.
IntelliSense tells me the origin(not yet renamed) Designer.cs is not found.
Now if I try to create anything on the blank form, the code is directly written in FormMain.cs.
How can I solve this?
Thanks.
Using Visual Studio 2019, I was following the C# WPF tutorial from Microsoft docs. Along the way, there is a step wherein you rename MainWindow.xaml to Greetings.xaml. When I did this, the design view was gone. Restarting Visual Studio fixes the design view. Of course, save your files before restarting.
Removing the form and adding it again to the solution fixes this issue. Here's how you can do:
Right click on the FormMain in the solution explorer and "Exclude From Project". Now right-click on the solution and click Add -> Existing Item and select the FormMain.cs from the same solution folder.
My Visual Studio is not showing a lot of the available classes in the IntelliSense auto-complete. For example, a project I'm working on has a reference to the Microsoft.Xna.Framework namespace, yet even after adding the using statement using Microsoft.Xna.Framework in a file, IntelliSense is unable to recognize classes like Texture2D and Rectangle. I can still type them in, however, without getting a compiler error. Any idea what's happening?
The IntelliSense detects standard libraries like System.Diagnostics but not any external ones.
It is not a NameSpace conflict issue because classes within the current namespace are also missing from the IntelliSense.
I have tried:
Restarting Visual Studio (With and without closing tabs)
Deleting the contents of %LocalAppData%\Microsoft\VisualStudio\14.0\ComponentCacheModel folder
Resetting import and export settings
What worked for me is unloading and reloading the project
If unloading/reloading the project doesn't work, try deleting the .suo file found in the SolutionName/.vs/ folder. The .vs folder is an auto-created, hidden folder so you will have to show hidden folders in order to see it.
I am using ReSharper. What worked for me:
Unload project.
ReSharper > Options > Environment > General > Clear caches
Close solution.
Exit Visual Studio.
Restart Visual Studio.
Reload project.
Do you have ReSharper or any other plugins installed? There sounds like a similar issue/solution here. It may be third-party plugins at play depending on what add-ons you have.
Try saving and reloading the files.
I don't know why it happens, but it happens to my work laptop occasionally, typically reopening the source file resolves it.
OK so probably not the best solution but it works. I reinstalled Visual Studio and the problem was fixed. Also, it hasn't shown up since (this happened about 3 months ago).
another dumb solution))) Determine which classes/namespaces are not showing up. Then go to that project where they are. In that project pick any .cs file copy its contents, then delete that file and create again))
Click on the class not showing and Change Build Action -> to Compile
it happens sometimes when you add class as content or other resources
I was recently asked to create an installer for a Windows Forms application that uses Entity Framework to comunicate to a database. I modified my program to create the database if it doesn't exist on the final user's computer, so it should work without problems. Problem is, I'm using installshield for Visual Studio 2012, and after building my installer, only 2 files were generated inside the install directory:
MyProgram.exe & MyProgram.exe.config
Problem is, I believe a EntityFramework.dll file should also be included for the program to work, but apparently, Visual Studio doesn't want to include it. I tried everything. I clicked on the properties of the EF model and selected the "Copy to Output" or "Copy if Newer", and nothing. I also tried to change my .edmx file´s properties where I switched Build Action: None to Build Action: Compile...but after that, my whole program wouldn't even build! It threw the following error:
A namespace cannot directly contain members such as fields or methods
And after double clicking the error to check where it happened, it opened the EDMX file in code, and apparently wanted me to add a namespace at the start of it...but this whole thing looks like XML...so why does it ask me for a namespace?
All I want to do is add my Entity Framework Model to my Primary Output, but nothing works. Or it doesn't appear in installshield at least. I know I can manually add "EntityFramework.dll" the file from the debug or release folder in my project/bin, but that just doesn't feel right. Should I just do that, or is there a reason why my Entity model isn't being added to my project output? Or why did my EDMX file threw a namespace error when I tried to switch the compile option from None->Compile???
Please help guys...I know it's a dumb mistake, but all I want is that the files required for my entity model to work on another PC be copied (As far as I know, all I need is that EntityFramework.dll and maybe EntityFramework.xml). Help?

In your installshield project (certainly in the same solution as your project), you should indeed see the primary.output of the project it depends on. If not, right click on IS project -> Project dependencies -> and check manually.
From te IS project tree, it is available in the "2) Specify your application data" -> "Files" where zou can specify the physical organisation and content of your installation directory.
On .primary.output -> right click -> dependencies from scan at build -> You should see a list of all auto-detected dependencies, enable/disable what you want... it works this way for me. Note that a build is required previously.
If the dll is not present in the list, you could also drop it in the installation directory tree on the left and the file will be embedded too.
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.

I am using VS2008/VS2010 with Resharper 5, TortoiseSVN 1.6.8.19260-x64, and AnkhSVN 2.1.8420.8. Most operations I do in Visual Studio are reflected fine in SVN, however, renaming folders in a project can cause problems when I try to submit my changes. Also all the namespaces in the C# source files under the renamed folder need to be updated to reflect the name change.
What is the best way to rename the main project folder or any sub folders and ensure there are no issues with SVN? Should it be done outside Visual Studio?
What is the best way to update all the namespace changes? Is search/replace the only way?
Are there any best practices regarding folder names and their contents?
Yes do your rename outside of Visual Studio.
Using TortoiseSVN in windows explorer, do your rename via the TortoiseSVN context menu on the folder in question. The project in Visual Studio will detect the changes on disk and ask you to reload.
You could also do an exclude from project in Visual Studio, then rename and then re-include the new path.
Edit: As per #Sander Rijken below, AnkhSVN tracks the rename and makes sure the rename is correctly registered in the svn working copy.
If you don't have AnkhSVN installed in addition to TortoiseSVN though this will not work and you have to do as I said above.
You should be able to rename folders inside Visual Studio when running AnkhSvn. Also when using refactoring tools like Resharper to change the namespace according to the new folder name, everything works as expected for me.
The Agent SVN plug-in implements the MS-SCCI interface which allows it to integrate with Visual Studio.
Since the MS-SCCI defines a file rename operation, that means Agent SVN can do file renames from within the IDE, as should any plug-in that also implements the MS-SCCI.
What I typically do when having to perform a folder renaming is first renaming the folder using tortoiseSVN, then Excluding/Including the folder in VS and finally renaming all the namespaces (with Resharper it's just a matter of going file by file and Alt+Enter(ing) on the namespace directive to rename as appropriate.
