NullReferenceException but checking for Null?
I’ll read those articles this evening and see if a more elegant solution is readily accessible or if I should just reorder and move on for now but find other times to implement the nullable reference types

These are the little things my brain doesn’t catch yet. Nice little gotcha moment.

NullReferenceException but checking for Null?
Literally out of order. I was thinking out of order meant before passing it to the method

NullReferenceException but checking for Null?
I haven’t as that’s not something I’m aware of. Still learning and kinda fumbling my way through. I’d love to do some reading or learning if you have knowledge you’d like to share on what you’ve mentioned here or any articles that clarify what you’re suggesting clearly

NullReferenceException but checking for Null?
Which I’m thinking the more elegant solution would be to disable the add course button until conditions are met. For now though that can wait

NullReferenceException but checking for Null?
Which i'm sure there's a much more elegant solution which I can work through later, but that wouldn't dereference it before checking for null, correct?

NullReferenceException but checking for Null?
So if I wrapped this something like this: 
private async void SaveCourseButton_Clicked(object sender, EventArgs e)
{
if (CourseName.Text is not null && InstructorName.Text is not null && InstructorPhone.Text is not null && InstructorEmail.Text is not null)
{
    Course course = new Course(id, CourseName.Text, StartDate.Date, EndDate.Date, StatusPicker.SelectedIndex, InstructorName.Text, InstructorPhone.Text, InstructorEmail.Text, CourseNotes.Text, 0, 0);
    var result = DataObjects.ValidateCourseInfo(activeTerm, course);
    if (result.Length == 0)
    {
        SQLFunctions.AddNewCourse(course);
        await Navigation.PopAsync();
    }
    else
    {
        await DisplayAlert("ERROR", result, "OK");
    }
}
}
private async void SaveCourseButton_Clicked(object sender, EventArgs e)
{
if (CourseName.Text is not null && InstructorName.Text is not null && InstructorPhone.Text is not null && InstructorEmail.Text is not null)
{
    Course course = new Course(id, CourseName.Text, StartDate.Date, EndDate.Date, StatusPicker.SelectedIndex, InstructorName.Text, InstructorPhone.Text, InstructorEmail.Text, CourseNotes.Text, 0, 0);
    var result = DataObjects.ValidateCourseInfo(activeTerm, course);
    if (result.Length == 0)
    {
        SQLFunctions.AddNewCourse(course);
        await Navigation.PopAsync();
    }
    else
    {
        await DisplayAlert("ERROR", result, "OK");
    }
}
}

NullReferenceException but checking for Null?
I'm checking for a null value on the fields that could potentially be blank, and if null, passing the error message back to be displayed, so I'm not sure why I'm getting the crash?

New ContentPages in .net MAUI app don't have InitializeComponent() methods
I’ll give that a try next time and see that if that resolves it rather than IDE restart. Thanks again!

New ContentPages in .net MAUI app don't have InitializeComponent() methods
@Absent_Reality closing and relaunching Visual studio seems to have fixed the issue. I battled this for hours this afternoon between google searches, looking at settings, deleting and recreating pages, etc.

New ContentPages in .net MAUI app don't have InitializeComponent() methods
namespace exists, its brand new, created by VS in the project, changed nothing. It auto adds the call for InitializeComponent(); but its not backed and the project won't build. I have to comment them out. I'm at a complete loss for what to do next

New ContentPages in .net MAUI app don't have InitializeComponent() methods
Fairly certain I do, but I’ll remote in to my desktop in a bit and check. I added all my usings above the namespace right after creation if I remember correctly.

New ContentPages in .net MAUI app don't have InitializeComponent() methods
That’s where I’m struggling. When I add a page in VS, I’m also adding it as a ContentPage(XAML) and it is not creating the InitializeComponent method. It puts the call to it in the body of the class but it isn’t linked to anything. I figured I was doing something wrong.
