Has anyone had this issue:
I have a class for which code autocompletion works (it can see its members, properties, etc.), I can hit F12 and see the class code. But, the class cannot be seen in the solution explorer, nor can I add it because Xamarin Studio claims it has already been added to the solution.
Switching tabs in the notebook usually highlights the classes in the solution explorer, but for this single class, it doesn't work.
Any ideas ?
Thanks.
Your class already exists in the file system. In VisualStudio you can choose to show hidden files in solution explorer and include it back in to the project. In Xamarin Studio you could right click on solution and choose Open Containing Folder, find the file on the disk and delete it, so you can add it again.

My C# project displays classes in the Solution Explorer some with the Designer View and some with the normal code editor:
AND
I Would like to make them all open with the code editor!
I went in the .csproj file and I noticed that for the classes marked as designer, I get a
<SubType>Component</SubType> tag. If I remove it manually, VS automatically re-add it to the item.
How to solve it? I searched but did not found anything usefull..
EDIT 1: I forgot to mention that this is a Console Application
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.
Recently in Visual Studio 2017 (Professional) when I right context click on a class declaration to extract the interface, I now only get an error. It used to work just fine.
Instead of extracting the interface, it gets this error instead(below)
I have not found anything with a web search related to this.
Any Ideas?
right click on class
select Extract Interface
on the Extract Interface click SelectAll (if everything is not already selected)
then click OK
observe error
..and here is the stack trace.
It may have something to do with how many layers of folders the class is located in or the fact that the namespace.class does not match the file structure.
Any suggestions to get it working again?
Closing and reopening the solution, Visual Studio, or the restarting windows 10 does not help.
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'm working on a windows form application. I start a new project. I delete the Form1 stuff from the new project. I go and add from existing in the solution explorer and choose Form1.cs, Form1.Designer.cs, and Form1.resx from another project. When I look at the designer Form1 just looks blank, like a new one would with none of the controls appearing. The program still compiles fine with all it's controls intact. Did I miss a step somewhere? I've closed and reopened the project etc. This happens every single time repeatedly so I believe I'm missing something but searching here or the rest of the web hasn't provided me a solution. Maybe it's just assumed to be known by everyone already?
I am just learning c# and Visual Studio so hopefully I didn't miss something stupid. I was following direction for how to do this from a book. Some projects are re-used to teach a new idea so they have you start a new project and add in existing items from the original to then work on the new idea.
In VS 2013 I chose "Add existing Item" and just selected the .cs files, don't add *.Designer.cs and *.resx files. Then waited for few minutes and restarted VS2013. Designer.cs and resx files appeared as associated with Forms but they were excluded. I right clicked them and chose "Include In Project". Then it worked fine.
Make sure that you are loading the Form1 that you think you are loading.
By default, Visual Studio 2013 (on Windows 7) will create a folder in Documents (C:\Users*Your user name*\Documents) called "Projects". Whenever you create a new project from within Visual Studio by going to File->New Project, Visual Studio will (by default) create a new folder in the Projects folder with the project name.
I think when you "delete" Form1, you're not actually deleting it, just removing it from the project. When you go to add Form1, you're just selecting it from the same project folder, when you actually wanted to load it from a different project folder.
Try this: In your current project (the one where you deleted Form1 and then added it), in the Solution Explorer, right click on the project, and select "Open Folder in File Explorer".
This will open the project folder on disk. Now, delete Form1.cs from within Visual Studio, and switch back to the project folder. If Form1.cs is still in that project folder, then you just removed it from the project. The actual files still exist on disk. When adding existing items, Visual Studio will typically default to the selected project folder.
I have a very strong suspicion that the Form1 that you are really looking for resides in a different project folder. Without knowing the book or tutorial you are following, I can't give you any hints as to where the Form1 you want is located.
