What Our Clients Are Saying

I worked with TechAvidus for over 2 years. The team is incredible. They are very responsive, responsible, dedicated, and capable. I strongly recommend the team for any project, however complex.

Alexander Z Stanley

Business Development Manager

Keshu, Bhavesh and their team are outstanding. Not only were they able to build a very sophisticated and customized portal for our thousands of customers, but they did so with skill, efficiency, professionalism, and offered wonderful suggestions and recommendations along they way. Even more impressive, they were able to do all of this in spite of the convoluted direction we provided them with.

We've since expanded our relationship with them to cover many additional web development jobs. Choosing to work with TechAvidus was one of the best decisions we've made in recent years. We recommend them unconditionally.

Rob Price

President, Gatekeeper Press

"The vendor did an outstanding job. They paid attention to every detail of project scope and made prompt corrections when needed. I would definitely work with them again."

Jason Lorenti

Digital Development Manager at Evolved Office LLC

Love to work with the team with a fair pricing and very valueable developers for komplex usecase. Actually we worked on a really big module based application and every work is awesome done.

Matthias Grdan

CEO | Digital Transformation

They were very responsive and the quality of the work was good. We experienced a few challenges with the back and forth during deliveries and some unexpected delays but they were always receptive to feedback and responded well to our concerns. I'd happily recommend them, especially Megha as the Project Manager and Savan as the Developer.

According to our experienced .NET programmers, If your application requires one of these the following, it's worth moving

Performance and Scalability
Cross-platform support
Microservices architecture and Containers

Microsoft .NET Framework is the first version of NET. It maintains working websites and services, mobile platforms, desktop applications, and many other applications for Windows. The Framework consists of a huge class library and implements language interoperability between various programming languages.

While .NET Framework and .NET Core have many standard components, there's a distinct distinction between them. .NET Core is an open source and cross-platform that is extremely helpful when a user needs multi-platform capabilities, microservice architecture, or docker. But in the case of desktop-based applications or apps using the NuGet package, .NET Framework is required.

The NET core technology has given businesses more effective and efficient programming methods. It makes it much more practical and more suitable for developers. Some of the common benefits of .NET core is

It is a cross-platform, cross-architecture Framework
Provides high performance and scalability.
Supports versioning side-by-side.
Supports serverless architecture on cloud
It provides the most increased security and docker compatibility, and synchronous patterns within MVC.

When it comes to docker, scalability and serverless architecture .NET Core is the most popular choice.
