create a graphical user interface using a WPF to allow a user to:
1. enter an unlimited amount of recipes and store it. the user must enter a recipe name, how many ingredients they want, the quantity and meassurement of each ingredient,the calorie of each ingredient and the food group of the ingredients and then the user should be able to enter how many steps the recipe has and a description of those steps.
2. the user must be able to choose from the recipes that were stored to be displayed and for each recipe the calories of each ingredient should be added up and displayed as the total calories, if the total calories exceed 300 the a warning message must be displayed in red.
3. the user should be able to scale the quantities of the ingredients in each recipe by a factor of 0.5 , 2 or 3 and the new qauntities should be displayed.
4. the user should be able to scale the recipe back to its original quantities and the be able to be displayed.
5. The user shall be able to filter the list of recipes by:
a. entering the name of an ingredient that must be in the recipe,
b. choosing a food group that must be in the recipe, or
c. selecting a maximum number of calories.

To achieve this, you'll need to define a few classes and create the necessary XAML layout and code-behind logic.
### MainWindow.xaml

### MainWindow.xaml.cs

{

}
}
}
private void SaveRecipe_Click(object sender, RoutedEventArgs e)
{
if (currentRecipe != null)
{
currentRecipe.Name = RecipeNameTextBox.Text;
recipes.Add(currentRecipe);
RecipeSelectionComboBox.Items.Add(currentRecipe.Name);
currentRecipe = null;
RecipeNameTextBox.Text = "";
NumberOfIngredientsTextBox.Text = "";
NumberOfStepsTextBox.Text = "";

}
private void RecipeSelectionComboBox_SelectionChanged(object sender, SelectionChangedEventArgs e)

{
continue;

{
if (recipe == null) return;

public class Recipe

public List<string> Steps { get; private set; }
public double TotalCalories => CalculateTotalCalories();
public Recipe()
{
Ingredients = new List<Ingredient>();

}
private double CalculateTotalCalories()
{
double totalCalories = 0;
foreach (var ingredient in Ingredients)
{
totalCalories += ingredient.Calories;
}

}
}
public class Ingredient
{
public string Name { get; set; }
public double Quantity { get; set; }
public string Measurement { get; set; }
public double Calories { get; set; }
public string FoodGroup { get; set; }
}
}
```
In addition, you need to create windows for inputting ingredients and steps.
### IngredientWindow.xaml
```xml
<Window x:Class="RecipeManager.IngredientWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Add Ingredient" Height="300" Width="400">
<StackPanel Margin="10">
<TextBox x:Name="NameTextBox" PlaceholderText="Name" Margin="0,10,0,10"/>
<TextBox x:Name="QuantityTextBox" PlaceholderText="Quantity" Margin="0,10,0,10"/>
<TextBox x:Name="MeasurementTextBox" PlaceholderText="Measurement" Margin="0,10,0,10"/>
<TextBox x:Name="CaloriesTextBox" PlaceholderText="Calories" Margin="0,10,0,10"/>
<ComboBox x:Name="FoodGroupComboBox" PlaceholderText="Food Group" Margin="0,10,0,10">
<ComboBoxItem Content="Vegetables"/>
<ComboBoxItem Content="Fruits"/>
<ComboBoxItem Content="Meats"/>
<ComboBoxItem Content="Dairy"/>
<!-- Add more food groups as necessary -->
</ComboBox>
<Button Content="Add" Click="AddButton_Click"/>
</StackPanel>
</Window>
```
### IngredientWindow.xaml.cs
```csharp
using System.Windows;
namespace RecipeManager
{
public partial class IngredientWindow : Window
{
public Ingredient Ingredient { get; private set; }
public IngredientWindow()
{
InitializeComponent();
}
private void AddButton_Click(object sender, RoutedEventArgs e)
{
Ingredient = new Ingredient
{
Name = NameTextBox.Text,
Quantity = double.Parse(QuantityTextBox.Text),
Measurement = MeasurementTextBox.Text,
Calories = double.Parse(CaloriesTextBox.Text),
FoodGroup = ((ComboBoxItem)FoodGroupComboBox.SelectedItem).Content as string
};
DialogResult = true;
}
}
}
```
### StepWindow.xaml
```xml
<Window x:Class="RecipeManager.StepWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Add Step" Height="200" Width="400">
<StackPanel Margin="10">
<TextBox x:Name="StepDescriptionTextBox" PlaceholderText="Step Description" Margin="0,10,0,10"/>
<Button Content="Add" Click="AddButton_Click"/>
</StackPanel>
</Window>
```
### StepWindow.xaml.cs
```csharp
using System.Windows;
namespace RecipeManager
{
public partial class StepWindow : Window
{
public string StepDescription { get; private set; }
public StepWindow()
{
InitializeComponent();
}
private void AddButton_Click(object sender, RoutedEventArgs e)
{
StepDescription = StepDescriptionTextBox.Text;
DialogResult = true;
}
}
}
```
This WPF application should now fulfill all the requirements listed. You can build and run it in Visual Studio to manage recipes, display them, scale ingredients, and filter based on the given criteria.
