Frequently Asked Questions
What Do ASP.NET Developers Do?
ASP.NET developers specialize in creating software solutions using Microsoft’s ASP.NET framework. With ASP.NET, software engineers can build websites and web applications using HTML, CSS, and JavaScript for the frontend and C# and Visual Basic for the backend. ASP.NET is a great tool for building solutions like online stores, personnel management solutions, or content management and inventory management systems.
Why Should I Hire DevTeam.Space as an ASP.NET Development Company?
A vetted community of expert dev teams, DevTeam.Space has been providing software development services since 2016.

We guarantee timely delivery, transparent communication, regular updates on the work progress, cost-efficiency, and ongoing support.
What Is the Difference Between ASP.NET Development and .NET Development?
ASP.NET evolved from .NET, Microsoft’s platform for building different types of apps that work natively on various platforms. Microsoft released ASP.NET in 2002 with a view to adapt .NET for web application development. ‘ASP’ stands for ‘Active Service Pages’ — HTML pages used to build the backend of web applications. Basically, ASP.NET and .NET have similar functionality, but ASP.NET is adapted to coding the backend for web pages and web apps.
All of DevTeam.Space expert developers go through a professional vetting process to validate their highest level of expertise in a particular technology stack, industries, and application types for commercial markets that correlate with the article's subject matter.
★Experience
All of DevTeam.Space expert developers possess 4 or more years of commercial software development experience. They are either mid-level or senior-level software engineers focusing on a particular technology stack, industry, or application type.
An integral part of Microsoft’s .NET framework, ASP.NET is a popular tool for crafting dynamic web applications and websites.
DevTeam.Space provides a wide range of ASP.NET development services, including custom ASP.NET web app development, ASP.NET MVC development, ASP.NET integration, and more. If you need assistance with your ASP.NET web application, submit your request and get a complimentary discovery call with one of our tech account managers.
With the ASP.NET development environment, software engineers can create web applications using three tools: Web Forms, ASP.NET MVC, and ASP.NET Web Pages. Although based on the .NET framework and not fully independent of each other, each of them targets different development styles.
For example, Web Forms come with a rich library of controls and components that contain HTML markup. The tool is especially suited for crafting complex, UI-focused websites quickly and efficiently.
The MVC (Model-View-Controller) architectural pattern gives full control over HTML and separates the code and markup. ASP.NET MVC has multiple features for test-driven development and is best suited for creating sophisticated mobile and single-page applications in line with the latest web standards.
The Web Pages tool puts HTML markup and server code in a single file. Developers can connect Web Pages-based solutions to databases, add videos, and include other features for creating dynamic and engaging websites.
ASP.NET is one of the most widely used platforms globally. Developers like it for many reasons, and here are some of the framework’s features that make it a great choice for crafting web apps.
1. ASP.NET is based on the Common Language Runtime, which means that applications can be written in almost any programming language.
2. Being a server-side framework, ASP.NET provides for faster app execution as the server processes the code before it is displayed in the browser.
3. With ASP.NET, developers can build native mobile apps and mobile websites. For building mobile apps, they need to use Web APIs to handle data access, authentication, and push notifications. For building mobile sites, programmers can use any CSS framework or open grid system.

The choice of ASP.NET development tools will depend on your specific project requirements. You can read about some of the top relevant technologies below.
ASP.NET Core
ASP.NET Core is a newer version of ASP.NET. It’s an open-source cross-platform framework that runs on Windows, macOS, and Linux. ASP.NET Core extends .NET and contains tools and libraries for building web applications and services.
What developers especially like about ASP.NET Core is its security-centered approach. ASP.NET has built-in features aimed at protecting apps from cross-site scripting and cross-site request forgery. It also provides a built-in user database with support for multi-factor authentication.
SQL Server
Our developers often use the ASP.NET framework together with Microsoft’s SQL Server. SQL Server is a relational database management system typically used to store and manage web app data. It can be deployed on Windows and Linux computers as well as on the Azure Virtual Machine.
Its core service is the Database Engine that stores and processes data. SQL Server supports integration of machine learning into enterprise workflows. Its other services include integration, analysis, reporting, data quality, master data services, and more.
Visual Studio
Visual Studio is Microsoft’s integrated development environment (IDE). It’s a comprehensive developer tool that offers a variety of features for a full-cycle development process. These include compilers, code completion tools, and extensions, among others.
Using ASP.NET with Visual Studio facilitates building the frontend client-side of an app. For example, this IDE offers drag-and-drop functionality to build user interfaces, which is way more convenient than writing code for each element. Our developers often make use of this tool when working with ASP.NET.
As a leading ASP.NET development company, DevTeam.Space builds top-notch web apps and websites for multiple industries. To learn more, you can get a complimentary discovery call with one of our account managers experienced in ASP.NET application development via the button below.
