What powers our .NET development services
Platforms and frameworks
We utilize .NET Core and ASP.NET Core for their cross-platform compatibility, enabling us to build applications that run seamlessly on Windows, Linux, and macOS. Blazor is used for creating interactive web UIs with C# instead of JavaScript, enhancing the development process. Entity Framework Core serves as a tool for data access, simplifying the database operations with its robust ORM capabilities. These technologies ensure that we can build modern, efficient applications that are scalable across various platforms and devices.
DevOps and clouds
Our DevOps practices are centered around automation, collaboration, and continuous improvement, critical for achieving agility and efficiency in the development process. We employ Continuous Integration (CI) and Continuous Deployment (CD) pipelines using Azure DevOps, GitHub Actions, or Jenkins, facilitating automatic code integration and deployment to reduce manual errors and speed up the release cycle. Cloud platforms like Azure and AWS are integral for building, deploying, and managing applications in the cloud.
Libraries, components, and APIs
Libraries and components integration, and API development ensures the delivery of high-quality solutions. NuGet packages provide libraries for various functionalities, from security enhancements to data visualization. Libraries like Newtonsoft.Json for JSON serialization/deserialization and Serilog for sophisticated logging are part of our toolkit. Additionally, integrating RESTful APIs and third-party services allows us to extend the capabilities of our apps, offering features that meet the specific needs of our clients.
Integrated environments for development
Integrated Development Environments (IDEs) like Visual Studio and Visual Studio Code are at the core of our development process. These IDEs offer advanced code editing, debugging, and testing features, along with extensions and integrations for various development needs. This way, they are indispensable tools for our developers. Their comprehensive capabilities enable efficient writing, testing, and debugging code in a unified environment, streamlining the development process and enhancing productivity.
Databases, testing, monitoring, QA, and reporting
Our approach to databases, testing, monitoring, QA, and reporting is based on using advanced tools and best practices to ensure the highest quality standards. For database management, we use SQL Server, PostgreSQL, and MongoDB, choosing the most suitable database system based on the project requirements. For monitoring and QA, we use Application Insights and Prometheus for real-time monitoring, coupled with SonarQube for continuous inspection of code quality. These tools and practices enable us to maintain high-quality standards throughout the development lifecycle, from initial coding to post-deployment.
Benefits of using .NET for software development services
-
Versatility
-
Increased productivity
.NET is known for its extensive class libraries, APIs, and tools, significantly reducing the amount of required code. This speeds up the development process and reduces the likelihood of bugs, making applications more stable and reliable. Features like a rich Integrated Development Environment (IDE), Visual Studio, and the .NET CLI (Command Line Interface) enhance productivity by providing developers with powerful tools to build, test, and deploy apps more efficiently.
-
Large community and support
The vast Microsoft’s and .NET software development communities provide continuous support and ensure access to the latest technologies and best practices. The community members share tutorials and ideas and help each other with documentation. Additionally, Microsoft’s continuous support and investment in .NET mean that the framework is regularly updated with new features and security enhancements, keeping it relevant and powerful.
-
Microsoft Ecosystem
.NET works seamlessly with other Microsoft products and services, such as Azure, Office 365, and Dynamics CRM. Such an integration enables developers to leverage a wide range of services and tools, enhancing apps functionality and user experience. The ecosystem also provides a platform for developers to build, deploy, and manage apps, reducing the complexity of implementing advanced features.
-
Scalability
.NET applications are designed with a project scalability in mind. The framework provides built-in features and services that enable applications to handle more users, transactions, and data without losing in performance. Whether it’s through vertical scaling — adding more power to the existing hardware, or horizontal one — adding more instances of a solution, .NET makes it easier to scale apps to meet business growth.
-
Security
.NET provides advanced security features to develop secure applications and protect your data. These include built-in authentication and authorization, data protection, secure communication, and threat management tools. The regular updates include security patches and enhancements, ensuring that applications built with .NET can protect against the latest threats.
