I confirm WimOmbelets answer given in the comments. This can apparently happen when you rename a class in VS2012 (I never had this in a prior version). 

I can't be sure this is the cause, but one thing I did different from my normal way is I used F2 to rename it as opposed to changing it and then pressing control-.

blocks|key|190875|text|当两个.resx文件指向相同的表单时，就会发生这种情况。主要发生在重命名表单时(其他原因可能适用，我不太确定)|type|unstyled|depth|inlineStyleRanges|entityRanges|data|190876|如果您的特定表单文件如下所示：|190877|Form1.cs
Form1.designer.cs
MyFormerFormName.resx
Form1.resx|code-block|syntax|javascript|190878|然后，这通常意味着您重命名了表单，但是Visual没有删除旧的.resx文件。手动删除文件(在本例中为MyFormerFormName.resx)后，在下一次构建时就会出现错误。|offset|length|style|CODE|190879|entityMap^0|0|0|0|1F|L|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|R|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|S|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|T|8|@$K|U|L|V|M|N]]|9|@]|A|$]]|$1|O|3|-4|5|6|7|W|8|@]|9|@]|A|$]]]|P|$]]

This can happen in the event of two .resx files pointing to the same form. Mostly happens when renaming forms (other reasons may apply, I'm not exactly sure)

If your particular form files looks like this:

<pre><code>Form1.cs
Form1.designer.cs
MyFormerFormName.resx
Form1.resx
</code></pre>

then that usually implies that you renamed the form but Visual Studio didn't remove the old .resx file. Once you delete the file (in this example <code>MyFormerFormName.resx</code>) manually, the error should be gone upon next build.

I thought that I would post on at least one random forum after encountering this error in hopes of easing someone elses problems. I searched many google sites and none had my exact problem. My cause was similar, but different in some ways.

I actually had a partial class spread across multiple files. this class was a form class. This was successful in itself and didn't cause a problem. However, this caused the new class to keep its unique file name while maintaining a split 'class Form' code. It was most likely not kosher practice, but none the less it happened at the time. It seemed like a good alternative to get a lot of cluttered code out of the way. Needless to say, next time I will just use regions or some other alternative.

The error then occured when I tried to take the code from the 2nd file and copy/paste into a new non form file with just a class, as I had intended upon essentially turning it into a library and making the code a little more proper and readable. As I didn't know exactly what had caused the error when it happened and had made a small plethora of changes, it took some time to track. Even after reversing the code, I managed to miss a pair of methods.

The methods for the main form containing the class Form with initializeComponent and form constructor (load). A 2nd copy of these methods appeared to result in the same error. Even after deleting the extra code and extra form and resx files. I even tried deleting the legitimate resx file since it was not actively needed. I was unable to effectively track it, because any errors pointed to the legit versions of these code segments. Ctrl+F and backup copies are your friends.

Hope that helps someone

This happened to me when I copied a form to reuse most of the functionality and then renamed the form. I went to the directory referenced, found that there was in fact only one file, copied the file in question, renamed it to reference the name of my new form, and then pasted the new file back in the directory.

I don't think this is a good practice (I'm new to C#) but it did work, instead of having to recreate everything. I also needed to update the form name in a few places throughout the solution, surprising in the original form as well as in the new form.

Copying forms does not seem like a good idea.

I had the same issue when I renamed one of my <code>Form</code> classes using <code>Ctrl + R + R</code> which VS provides to rename things by default.

Then I somewhat got two classes with the same class name on 2 different files (*.cs).

<pre><code>class Bar { ... } // From Bar.cs
class Bar { ... } // This should've been Foo, from Foo.cs
</code></pre>

The two <code>Bar</code> indicating the same resource file that one of them shouldn't.

It's a trivial issue but sometimes could be hard to find the cause because looking at cs files just can't say which one is what you should look for.

I had the issue and it was caused because I had a partial class of a custom control.

I had accidentally created a .resx file for the partial 

I think I did this by hitting shift F7 on the partial class and producing the empty designer form. 

Removing the .resx file on the partial class resolved it for me. I was using version control and it was showing that it was a new file.

Hope this helps

blocks|key|394722|text|当我意外地生成与业务对象同名的迁移时，我遇到了这个问题。解决方案是删除迁移，然后用不同的名称创建一个新的迁移。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|394723|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I got this problem when I accidentally generated a migration with the same name as a business object.
The solution is to delete the migration and then create a new one with a different name.

blocks|key|394781|text|通常，如果您创建这样的迁移|type|unstyled|depth|inlineStyleRanges|entityRanges|data|394782|Add-Migration+"UpdateProducts"|code-block|syntax|javascript|394783|Visual将创建一个类名为UpdateProducts的迁移。如果稍后使用相同的迁移名添加一个新迁移，它将生成一个类名为UpdateProducts1.的迁移，它将自动将一个递增的数字作为后缀添加到末尾。每次生成一个新的迁移，这个数字就会增加一个。|394784|在我们的例子中，由于某种原因，VS被搞糊涂了，并开始使用与现有迁移相同的类名生成后续迁移，这样就出现了两个具有相同名称的自动迁移。|394785|只需更改新迁移的类名就可以清除问题。|394786|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@]|9|@]|A|$]]|$1|I|3|J|5|6|7|R|8|@]|9|@]|A|$]]|$1|K|3|L|5|6|7|S|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

Normally, if you create a migration like this 

<pre><code>Add-Migration "UpdateProducts"
</code></pre>

Visual Studio will create a migration with a class name like UpdateProducts. If you add a new migration later using the same migration name, it will generate a migration with a class name like UpdateProducts1., automatically adding an incremented digit to the end as a suffix. Every time you generate a new migration, the number goes up by one.

In our case, for some reason, VS got confused, and started generating subsequent migrations with the same class name as existing migration, so that that there were two auto generated migrations with the same name.

Simply changing the class name of the new migration clears the problem.

blocks|key|191354|text|对我来说，问题是复制和粘贴一个.aspx，而不是在类文件后面重命名代码以匹配复制的aspx文件的名称。更改后面的代码和设计器类名是有效的。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|191355|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

For me the issue was copying and pasting a .aspx, and not renaming the code behind class files to match the name for the copied aspx file. Changing the code behind and designer class names worked.

I just got this issue using VS 2019 community edition.

I didn't have duplicate .resx files. I didn't have duplicate .cs files.
I couldn't find the solution online.

To fix the problem, I cleaned the solution and then restarted VS.
Not sure why, but it worked. Hope this helps.

blocks|key|559567|text|在我的例子中，我不得不在Note%2B%2B中打开.resx文件，并在EmbeddedResource标记中查找.resx文件。我发现了一些带有奇怪语言后缀example.aa.resx的奇怪.resx+--其他文件是普通文件，没有语言后缀或*.ar后缀，我删除了令人毛骨悚然的嵌入式资源标签，并为我解决了这个问题。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|559568|entityMap^0|L|5|V|G|1G|5|22|F|2K|5|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]|$9|M|A|N|B|C]|$9|O|A|P|B|C]|$9|Q|A|R|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|S|8|@]|D|@]|E|$]]]|G|$]]

I had this problem today.
Some how the Form.Designer had an extension of .resx, for my solution it was TestForm.Designer.resx. There was already a TestForm.resx. I cleaned the solution, closed down VS, deleted the TestForm.Designer.resx file, and then restarted VS. I still had the error.
I then closed down VS and opened the .proj file using NotePad++ and found that the TestForm.Designer.resx was still referenced. I deleted the embedded resource.
<pre><code>&lt;EmbeddedResource Include=&quot;TestForm.Designer.resx&quot;&gt;
 &lt;DependentUpon&gt;TestForm.Designer.vb&lt;/DependentUpon&gt;
&lt;/EmbeddedResource&gt;

Then I opened VS and built....It work's again!

As @WimOmbelets stated in his 2013's answer, copying a Form is a very sure way to reproduce this annoying error, at least in VS 2017, 2019 and 2022.
As Vince De Giorgio said in his 2019's answer, I too didn't have duplicate .resx or .cs files and I didn't have duplicate ...EmbeddedResource Include= .../&gt; tags in .csproj.
Deleting .resx files (icons gone, obvious) for both involved forms, clean the solution and then restart VS is a poor man's way to solve, because every time I add again an icon or another resource, same annoying error. It is still worse: to recover, I had to Git stash all modifications; if I revert manually all changes, to the point that Git does not recognize any changes, the error continues (!!!) even after cleaning, restarting VS and rebuilding.
To fix the problem in VS 2019 and 2022:
Every time that I want to copy a form, I:
<ol>
<li>Exclude Form to be copied from project (exclude, DO NOT DELETE!)</li>
<li>In Windows Explorer I create a Form's copy and open them (.cs and designer.cs) with Visual Code (whatever)</li>
<li>In Visual Studio I create Add a New Form with a different name - of course</li>
<li>Paste back designer.cs and .cs codes from VS code; change namespace, class name and Ctor</li>
<li>Include again in Project previous Form</li>
<li>Enjoy</li>
</ol>
Never more had this problem.

I had the same issue in Visual Studio 2022 with a WinForms application in .NET 6.
In this case, I had added a partial class in it's own <code>.CS</code> file to handle custom setup outside of the <code>Designer</code>-generated <code>InitializeComponent</code>.
The next time that I opened the file, Visual Studio 2022 tried to open this in the WinForm Designer. This added a redundant <code>.resx</code> file to the project.
Delete the newly added <code>.resx</code> to correct the error.

Recently I created new <code>Form</code> called <code>WorkersScreen</code>. When I try to run the project I got this error:

What does it mean and how does one resolve it?

Two output file names resolved to the same output
