[WIP] Add missing components for Blazor CRUD application

[Copilot]

• Analyze existing repository structure
• Fix existing C# files (ApplicationDbContext.cs, EmployeeRepository.cs)
• Create BlazorCRUD.csproj project file with NuGet references
• Create Blazor app shell files (App.razor, _Host.cshtml, _Imports.razor)
• Create Blazor UI pages (Pages/Index.razor, Pages/Employees.razor)
• Create Blazor shared components (Shared/MainLayout.razor, Shared/NavMenu.razor)
• Create configuration files (appsettings.Development.json, Properties/launchSettings.json)
• Create wwwroot files (wwwroot/css/app.css)
• Create Database/SampleData.sql with sample employee records
• Create documentation (SETUP.md, DATABASE_SETUP.md)
• Validate the build compiles successfully

Original prompt

The BlazorCRUD repository is incomplete. Multiple critical files are missing that are required to create a functional CRUD application.

Missing Components:

1. Blazor UI Pages (CRITICAL):

• Pages/Index.razor - Home landing page
• Pages/Employees.razor - Main employee management component with CRUD UI
• Shared/MainLayout.razor - Master layout template
• Shared/NavMenu.razor - Navigation menu component
• App.razor - Router and app shell
• _Host.cshtml - Blazor host page
• _Imports.razor - Global using statements for Blazor

2. Database Layer (CRITICAL):

• Database/CreateEmployeeTable.sql - SQL script to create Employees table
• Database/StoredProcedures.sql - CRUD stored procedures
• Database/SampleData.sql - Sample employee records

3. Data Access Layer:

• Models/Employee.cs - Employee model with validation
• Data/ApplicationDbContext.cs - EF Core DbContext
• Repository/IEmployeeRepository.cs - Repository interface
• Repository/EmployeeRepository.cs - Repository implementation

4. Configuration Files:

• BlazorCRUD.csproj - Project file with NuGet references
• appsettings.Development.json - Development settings
• Properties/launchSettings.json - Launch configuration
• wwwroot/css/app.css - Application styles
• wwwroot/index.html - Static index page

5. Documentation:

• SETUP.md - Complete setup instructions
• DATABASE_SETUP.md - Database creation and configuration guide

2. Employee list view with pagination/sorting
3. Add/Edit modal forms
4. Delete confirmation dialog
5. Full CRUD API endpoints (GET all, GET by ID, POST, PUT, DELETE)
6. Repository pattern with async operations
7. Entity Framework Core integration with SQL Server
8. Error handling and validation
9. Responsive Bootstrap UI
10. SQL stored procedures for database operations
11. Sample data for testing

Technology Stack:

• .NET 5.0
• Blazor Server
• Entity Framework Core 5.0
• SQL Server
• Bootstrap for styling
• Swagger for API documentation

The following is the prior conversation context from the user's chat exploration (may be truncated):

Assistant: I see! The appsettings.json file wasn't created. Let me create it for you now:

Assistant: Now let me also create the missing Program.cs and Startup.cs files:

User: @Copilot Accepted Confirmation: Are you sure?

Assistant: Perfect! Now let me create the Program.cs file:

User: Ok

User: @Copilot Accepted Confirmation: Are you sure?

User: go ahead

Assistant: I notice the tool is having issues. Let me use an alternative approach to create these files:

User: @Copilot Accepted Confirmation: Are you sure?

User: go ahead

Assistant: I'm experiencing issues with the file creation tool. Let me provide you with a manual setup guide instead:

📋 MANUAL SETUP - Create Files Locally

Since the automated file creation is having issues, here's how to create all needed files manually in Visual Studio 2022:

Step 1: Create the Project Structure Manually

1. Open Visual Studio 2022
2. Create a new ASP.NET Core Web Application project named BlazorCRUD
3. Choose .NET 5.0 as the target framework
4. Select Blazor Server App template

Step 2: Create Folders

Right-click on project → New Folder and create:

• Models
• Data
• Repository
• Controllers
• Pages
• Shared

Step 3: Create Models/Employee.cs

Right-click Models → New Item → Class → Name it Employee.cs

using System;
using System.ComponentModel.DataAnnotations;

namespace BlazorCRUD.Models {
    public class Employee {
        [Key]
        public int EmployeeId { get; set; }

        [Required(ErrorMessage = "Employee Code is required")]
        [StringLength(50)]
        public string EmployeeCode { get; set; }

        [Required(ErrorMessage = "First Name is required")]
        [StringLength(50)]
        public string FirstName { get; set; }

        [Required(ErrorMessage = "Last Name is required")]
        [StringLength(50)]
        public string LastName { get; set; }

        [Required(ErrorMessage = "Email is required")]
        [EmailAddress]
        [StringLength(100)]
        public string Email { get; set; }

        [Required(ErrorMessage = "Phone Number is required")]
        [Phone]
        [StringLength(15)]
        public string PhoneNumber { get; set; }

        [Required(ErrorMessage = "Department is required")]
        [StringLength(50)]
        public string Department { get; set; }

        [Required(ErrorMessage = "Designa...
