Не найден метод, пригодный для переопределения

Здравствуйте! Помогите, пожалуйста, разобраться с тонной ошибок. Пишу маленький графический редактор, получаю ошибку CS0115 ‘»Form1.Dispose(bool)»: не найден метод, пригодный для переопределения, пробовала менять имя неймспейса, добавлять дополнительные элементы, дополнительные атрибуты классов partial, initialized, ошибки не уходят. Прилагаю код и файл Designer

For an assignment I’ve had to convert a fractal rendering program from Java to C# and I think I’ve done it but when i try to run it I get the error that is present in the title and I have no idea why it is happening. This is the code for the renderer itself which presents me with no errors:

and this is the code that is used for the form designer which was auto generated and I’m not sure why an error is being presented because I’ve never had one before:

I have looked at other questions asking about similar problems, but to my understanding my namespace and form name are correct, but am still giving me the error code
Form1.Dispose(bool): no suitable method found to override
What else can give this problem besides differering names for namespace and form in form1.designer.cs and form1.cs?

Anyone knows how to deal with this??
error is ‘DeviceApplication1.Form1.Dispose(bool)’: no suitable method found to override
This is found in the form1.designer.cs
Thanks in advance

The top of your form1.cd (so not talking about the form1.designer.cs) should look like:
Code Snippet
public partial class Form1 : Form
{
and I think yours looks like:
Code Snippet
public partial class Form1
{
In short: your form1 is a class. The class inherites from the Form class… That means it is in fact a form, but some things might be different. Like employee and neighbour both inherit from human, but the two will react different if you ask them to work 40h/week.
In your case of form1, the compiler changed (=> override) the void Dispose(Bool disposing) from the class Form, like it always does. But because you probably (accidentely) removed the inheritance, it had no method Dispose(Bool disposing), so it can’t find what you are trying to change (=> override) there.
