❔ MC3050 compiler error

I added a new project with some custom WPF controls to my project's dependencies. I then added the control to my form, but while the designer accepted the control happily, the XAML compiler is issuing errors that it can't find the control. I'm lost as to why. Same with bindings to the some properties declared by my form. I've heard deleting the .vs folder can fix these problems, but that reset a lot of things. Does someone have a better solution? I have xmlns:local="clr-namespace:BestChat.IRC.Global.View" and xmlns:IrcCtrls="clr-namespace:BestChat.IRC.Global.View.Ctrls;assembly=BestChat.IRC.Global.View.Ctrls" declared on the root element. The binding that complains about not being able to find the dialog class is

{Binding Msg, Mode=OneWay, NotifyOnSourceUpdated=True, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type local:NetworkEditorDlg}}}

. The usage of the control is <IrcCtrls:NetworkLogInModesComboBox ... and that control is declared as NetworkLogInModesComboBox in namespace BestChat.IRC.Global.View.Ctrls in the assembly BestChat.IRC.Global.View.Ctrls.dll.

I posted here as no one responded in #chat. Too busy there.

the XAML designer IS a little notoriously buggy if you really thing you have everything right, close and restart Visual Studio, completely

Will PittengerOP•14mo ago

OK.

JakenVeina•14mo ago

you can also get a ton of crap build errors in XAML if you have just one error in your C# code otherwise, the error is pretty explicit remember what the problem was last time 😉 (I think that was you)

The control now loads, but it still fails to find the form for binding.

Was this issue resolved? If so, run /close - otherwise I will mark this as stale and this post will be archived until there is new activity.

Will PittengerOP•14mo ago

Nope.

JakenVeina•14mo ago

what does this mean?

Will PittengerOP•14mo ago

Well, I have a binding in NetworkEditorDlg with

{CalcBinding:Binding !Ready, Mode=OneWay, NotifyOnSourceUpdated=True, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type local:NetworkEditorDlg}}}

. I didn't know if ElementName=window would find properties I declare in NetworkEditorDlg.

if they're dependency properties, it would
