一次运行的C＃项目中出现错误-未找到合适的方法来覆盖

Question

In short, I'm building an addin for Outlook in C# and I've ran into a bit of a panic-situation. Please forgive if some of the information I provided is not relevant to solving my problem, but I cannot diagnose where this issue came from or why.

My problem is as follow: At an early part of my code, I have...

protected override Microsoft.Office.Core.IRibbonExtensibility CreateRibbonExtensibilityObject()
{
    return new Ribbon1();
}

The problem is that now, all of a sudden, I get:

Error 1 'asd.ThisAddIn.CreateRibbonExtensibilityObject()': no suitable method found to override

( asd is just the namespace I'm using)

Up until now, I was essentially done, and decided to start my construction on another project.

Upon returning to my Outlook addin, I find this and other errors such as:

Error 2 The name 'Properties' does not exist in the current context

What could possibly have happened?

Like I said, I left this project essentially done, and came back to nothing working.

Please, I'm really desperate here, as I can't see what the problem is.

Answer 1

Right, it might not be a very technical answer, but the following is what I did that solved said issue for me:

1. Find YourClassNameHere.designer.cs (usually found in the solution directory)
2. Make sure Visual Studio or YourEditorHere is completely closed.
3. Delete YourClassNameHere.designer.cs from the directory.
4. Reboot (this one might not be as mandatory, but I had to reboot to get it working).
5. Success!

I know it's a bit of a non-technical and flimsy solution to the problem, but it worked for me so hopefully it can work for someone else too.

Answer 2

you have to create your class by inheriting AddInBase class as follows.

public partial class ThisAddIn : AddInBase

without inheriting a class how you can override a method of the base class?
