WPF properties not defined - settings 'not supported'

i presume this is because in .net7 settings was moved out of properties and into solution explorer, but i don't know how to refer to it now. Help 😠

What you have is correct but I suspect based on your error messages you did not add the properties namespace in your xaml. At the top of the xaml document you will see things like this:

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

These are xaml namespaces, similar to using statements in C#. You need to add your properties namespace to this section like this:

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:properties="clr-namespace:{yourproject}.Properties"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:properties="clr-namespace:{yourproject}.Properties"

just replace {yourproject} with whatever your projects namespace is. You can find a working example of what this looks like here: https://github.com/AlexLexicon/Discord.Example.BindingSettings

WPF doesn't default to it's applications accessing it's own properties by default? ....i swear i'm trying to like wpf....i swear i'm trying to like wpf.... @Alexicon Now i get the name "Setting" does not exist, but...eh?

in your binding try Settings with an 's' at the end?

Dawnbomb•2y ago

Didn't work, although im pretty sure its supposed to be looking for ColorMode i just included Setting (now Settings) there to test incase

Alexicon•2y ago

what part did you change? You changed the source to "properties:Settings.Default"

Dawnbomb•2y ago

oh I didn't realize i had done that as i tested various things but still errors
