SimpleToDoList button binding not working for me

[mscheaf]

I am trying the SimpleToDoList sample and it is throwing the error

The property 'AddItemCommand' does not exist on 'SimpleToDoList.ViewModels.MainWindowViewModel'

On this

<TextBox.InnerRightContent>
                <Button Command="{Binding AddItemCommand}">
                    <PathIcon Data="{DynamicResource AcceptIconData}"
                              Foreground="Green" />
                </Button>
            </TextBox.InnerRightContent>

My MainWindowViewModel very clearly has this function

[RelayCommand(CanExecute = nameof(CanAddItem))]
private void AddItem()
{
    // Add a new item to the list
    ToDoItems.Add(new ToDoItemViewModel() { Content = NewItemContent });

    // reset the NewItemContent
    NewItemContent = null;
}

So why can't it find it?

Hi @mscheaf if the error is showing up in the IDE please try to build or run once. The sourcegen might not have it picked up yet. If running does throw, please upload the project without bin and obj here so I can have a deeper look. From the snippets it looks all okay.

SimpleToDoList.zip

I have cleaned and built multiple times. I feel like something is hung up with the generated background code.

If I try RemoveItemCommand it doesn't work either. And thank you for your response too! Appreciate it.

You know I just unzipped what I sent you and ran it and it works fine. I even deleted the bin and obj folders from the original and it still didn't work but the unzipped folder on my desktop runs fine. The only difference is the original is part of a solution. There must be some hidden files at the solution level I am not seeing, will look more into this.

I can't help with this, but glad you found something at least.

[mscheaf]

OK so I created a whole new solution and redid everything from the start, and it gives me the same error. But now it will at least run, and the preview works it just lists a problem and a red squiggle line on every binding to a relay command I have. And again, this works fine if I just open the project folder and bypass the solution, it is only when I open the solution folder that it gets angry. I don't know.

As you said, the zip works fine. Maybe you can also include the solution? Make sure your IDE and plugins are up to date.

I have made two new projects on their own solutions and the same things happens. Again, it previews and runs fine but there is always a "problem" listed. As you can imagine that will not help me when I try to find real problems later on if I have a list of dozens of fake ones. My plugins auto-update and I just updated VS Code yesterday. slnx files are nothing but Solution->Project->Path xml tags. there must be something going on in the background of my install that isn't working properly. Is there something that would require special permissions or rights to do? A lot of this computer is locked down by IT, including changes to certain folders like Program Files and Windows (yeah yeah, I know).

That could be it. Also check out the existing issues for this (relative new) addon: https://github.com/AvaloniaUI/AvaloniaPro/issues?q=is%3Aissue%20state%3Aopen%20label%3A%22visual%20studio%20code%22
