C# Error received when binding in Xaml

[jv1597]

I get the following error when trying to bind a simple Xaml TextBlock object to C#:
Error Message: "Exception Unhandled: 'Microsoft.ui.xaml.dll' or one of its dependecies: The specified module could not be found. (0x8007007E)"

The App.g.i.cs file brought up highlights 'XamlCheckProcessRequirements();' in its code. I'm using Visual Studio to bind a xaml object to a data-type returned by a simple function 'View1'. Here is what I have coded so far:

Xaml Code:

<Grid Width="Auto" Height="Auto" Background="#1f1f1f">
    <TextBlock Text="{Binding View1}"></TextBlock>
</Grid>

C# Code:

using Microsoft.UI.Xaml;
using Microsoft.UI.Xaml.Controls;
using Microsoft.UI.Xaml.Controls.Primitives;
using Microsoft.UI.Xaml.Data;
using Microsoft.UI.Xaml.Input;
using Microsoft.UI.Xaml.Media;
using Microsoft.UI.Xaml.Navigation;
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Runtime.InteropServices.WindowsRuntime;
using Windows.Foundation;
using Windows.Foundation.Collections;


namespace drawing_board
{

    public sealed partial class MainWindow : Window
    {
        public MainWindow()
        {
            this.InitializeComponent();
        }

        ViewModel1 viewModel1 = new ViewModel1();

        class ViewModel1
        {
            public static double View1()
            {
                double num1 = 321;
                double num2 = 654;
                double sum = num1 + num2;
                return sum;
            }
        }
    }
}

I tried instantiating the class for the binding context as shown with 'ViewModel1 viewModel1 = new ViewModel1();'. I would like to get the data-type value imported as the value for the 'Text' property in 'TextBlock' as shown in the xaml code above. I would like to know why the binding code is throwing an exception.

Hi there,
Are you sure you have that package installed? I would first check under Nuget Package Manager
