University Learning Management System

University Learning Management System (ULMS)

I developed a comprehensive University Learning Management System (ULMS) using Blazor, leveraging its capabilities for creating interactive web applications with C# and .NET. The ULMS is designed to support various user roles, including Students, Instructors, and Admins, each with specific functionalities.

Key Features and Use Cases

Students

• View Attendance: Students can check their attendance records.
• Download Books: Access and download course materials and books.
• View Classroom: Get information about their classrooms and schedules.
• View Marks: Check their marks and academic performance.
• Submission of Quiz/Assignment/Sessional: Submit assignments and quizzes online.
• View Semester Calendar: Keep track of important academic dates and events.

Instructors

• Upload Books: Instructors can upload books and reading materials for students.
• Upload Marks: Enter and update student marks.
• Upload Past Papers: Provide access to past exam papers.
• Mark Attendance: Record student attendance.
• Make Announcements: Post announcements and updates for students.
• Create Submissions: Create and manage assignments, quizzes, and sessionals.
• Upload Course Materials: Upload additional course-related materials and resources.

Admins

• Manage User Accounts: Administer user accounts, including adding, removing, and updating user information.
• Manage Courses: Create, update, and manage courses offered by the university.
• Login: Secure access to the admin dashboard.
• Create Events: Organize and manage university events and activities.

Technologies Used

• Blazor: For building the interactive user interface using C# and .NET.
• ASP.NET Core: Backend framework for handling server-side logic.
• Entity Framework Core: ORM for database interactions.
• HttpClient: For making HTTP requests to the backend API.
• Dependency Injection: Ensuring modularity and easy maintenance of the codebase.

This LMS provides a robust platform for managing university operations, enhancing the educational experience for students, and streamlining administrative tasks for instructors and admins.

Setup

install packages

<PackageReference Include="Microsoft.EntityFrameworkCore" Version="7.0.17" />
<PackageReference Include="Microsoft.EntityFrameworkCore.Design" Version="7.0.17">
    <PrivateAssets>all</PrivateAssets>
    <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
</PackageReference>
<PackageReference Include="Npgsql.EntityFrameworkCore.PostgreSQL" Version="7.0.11" />

create folder Shared/Models

run the following command in Shared

dotnet ef dbcontext scaffold "Host=aws-0-us-west-1.pooler.supabase.com;Port=5432; Database=postgres; Username=postgres.cvikrfiqwuwfbnfqxvpv; Password=IOrLlIapntLwoLbD" Npgsql.EntityFrameworkCore.PostgreSQL --table account -o Models/

create folder Server/Data

move 'Shared/Models/PostgresContext.cs' to 'Server/Data/PostgresContext.cs'

replace 'namespace Shared' to 'namepsace Server' in Server/Data/PostgresContext.cs

import 'using Shared.Models' in Server/Data/PostgresContext.cs

add connection string in appsetting.json

{
    "ConnectionStrings": {
        "connectionstring": "Host=aws-0-us-west-1.pooler.supabase.com;Port=5432; Database=postgres; Username=postgres.cvikrfiqwuwfbnfqxvpv; Password=IOrLlIapntLwoLbD"
    }
}

add Services in Server/Program.cs (make sure to import required libraries)

var conn = builder.Configuration.GetConnectionString("connectionstring");

builder.Services.AddEntityFrameworkNpgsql().AddDbContext<PostgresContext>(opt => opt.UseNpgsql(conn));

Update (whenever database schema is changed)

run the following command in Shared

dotnet ef dbcontext scaffold "Host=aws-0-us-west-1.pooler.supabase.com;Port=5432; Database=postgres; Username=postgres.cvikrfiqwuwfbnfqxvpv; Password=IOrLlIapntLwoLbD" Npgsql.EntityFrameworkCore.PostgreSQL --table account -o Models/

or

dotnet ef dbcontext scaffold "Host=aws-0-us-west-1.pooler.supabase.com;Port=5432; Database=postgres; Username=postgres.cvikrfiqwuwfbnfqxvpv; Password=IOrLlIapntLwoLbD" Npgsql.EntityFrameworkCore.PostgreSQL --table tablename1 --table tablename2 -o Models/ --force
