.NET libraries and tools TwinCore knows

Tech-savvy clients and partners will definitely appreciate the stack of .NET instruments our team uses and supports. The array of these instruments can handle the project with any difficulty.

Frameworks

Libraries

Third-Party Components

.NET 1.1.

.NET 1.1. is part of legacy apps and is required for backward compatibility to keep your software and server up to date to running without errors

.NET Core 2.0

.NET Core 2.0 and above is the most common framework we use. It is the best .NET Framework to build apps with a high level of performance for cross-platforms

ASP.NET Web Forms

ASP.NET Web Forms is another field of our expertise, especially when we need to upgrade old web apps. This framework helps to develop complex web forms and feature-rich apps

ASP.NET MVC

ASP.NET MVC helps to build scalable web apps with the Model View Controller technology. Each component is responsible for a specific role, so debugging and maintenance become easy

ASP.NET Razor Pages

ASP.NET Razor Pages is the framework for developing dynamic user-friendly web applications. Razor Pages is a simple and fast way to build a web application with the Razor syntax for custom page development, layout design, and data binding

Blazor-based apps

Blazor-based apps are interactive and can handle a high level of performance, seamless user experiences, and interactive web apps from C#

Entity Framework

We use Entity Framework to simplify database operations with .NET objects. It supports data-heavy applications, lazy loading, caching, and performance optimization following best practices in database design

RabbitMQ, Kafka, AWS SQS, MSMQ

These messaging systems help us build fast, event-driven applications. They enable real-time data streaming, quick communication between services, and scalable architecture

Redis, Memcached

These in-memory caching tools boost application speed by delivering fast responses and reducing database load. Redis is especially effective for high-throughput .NET systems

Hangfire, Quartz

We manage background tasks and job scheduling using Hangfire and Quartz. They ensure responsive behavior and efficient execution of background processes

Azure Functions, AWS Lambda

For serverless architecture, we use Azure Functions and AWS Lambda. These tools let us build scalable, event-driven cloud applications that reduce infrastructure costs

IIS, Kestrel, Nginx

We use these servers for hosting, load balancing, SSL termination, and request handling in .NET web applications

Jenkins, Azure DevOps, Docker, Kubernetes

CI/CD automation tools like these let us streamline testing, integration, and deployment processes. They improve release speed and code quality

ELK, DataDog, Azure AppInsights, NewRelic

These monitoring platforms give us real-time visibility, log aggregation, and performance metrics to ensure system reliability and fast troubleshooting

NDepend, SonarCloud, SonarQube

These code analysis tools help maintain high code quality by identifying technical debt, code smells, and architectural issues early

Telerik

TwinCore team builds interactive user interfaces with Telerik components suitable for charts and grid control features. It is an important tech stack for agile project management, collaboration, .NET development, and testing services

DevExpress

We use DevExpress components to build data-based applications because this tech suite offers data control and reporting/analytics tools. Our DevExpress models make the apps run faster and improve business operations through their powerful data grid, reports, and dashboard tools

Syncfusion

Syncfusion’s Essential Studio is a software package we use because it offers over 1.900 UI components and frameworks like .NET, Blazor, MAUI, Angular, JavaScript, React, Vue, WPF, etc. Thanks to these components we can build modern web apps with such complex features as data grids, schedules, and charts. Syncfusion is lightweight, responsive, and modular, so our developers prefer this package over others

.NET CMS we know

Umbraco

Umbraco development for content-driven websites and multi-site setups. We build custom components, structured content models, and integrations with CRM and ERP systems, and handle performance optimization for larger editorial teams.

Orchard

Orchard development for modular and highly flexible websites. Suitable for projects that require custom features, reusable components, and tailored admin experiences.

OrchardCore

Orchard Core development for modern, scalable builds. We focus on clean content architecture, custom modules, and setups designed for multi-tenant or multi-brand environments.

Kentico

Kentico development for enterprise CMS and DXP use cases. This includes content and marketing workflows, personalization-ready structures, system integrations, and platform upgrades for long-term corporate projects.

Sitefinity

Sitefinity development for corporate websites and portals. We work on page structures, content governance, custom widgets, and integrations with analytics and internal systems.

nopCommerce

nopCommerce development services for .NET-based e-commerce platforms. This includes store setup, custom plugins, payment and shipping integrations, advanced catalog logic, and ERP or CRM connectivity for scalable online stores.

.NET architecture we use

As an experienced .NET development company, TwinCore makes sure that all the projects we help to develop are based on a solid, safe, and cost-effective architecture that is ready to meet the challenges of modern software development.

We use such .NET architecture models:

N-Tier Architecture

N-Tier Architecture divides the app’s functions into presentation/interface, business/core, and data-handling layers to manage the user interactions using this app, platform, or website. Such architecture solutions use multiple stacked layers to build applications with unique custom needs.

Microservices

Microservices work through .NET Core and additional streaming tools like Redis, RabbitMQ, and Kafka to handle large volumes of data while working with different systems. Our team helps you divide large applications into smaller microservices that grow independently to create a complete system for managing and distributing “heavy” applications. This solution is more cost-effective than other models.

Domain-Driven Design (DDD)

Domain-Driven Design (DDD) connects business domains directly to the related software elements. It is a complicated system that can be developed and supported only by experienced .NET developers.
