- Web app creation.
The services represented on the Microsoft Learn for experts who would like to learn more, a true game-changer as the special server-side framework ASP .Net that is also used for website crafting owing to its open-source nature and multi-platform support that lowers the overall cost and is reliable for most firms.

- Mobile app building.
.Net is the way to build a native application, well, with the usage of Xamarin, like a cornerstone for the whole offer so it’s vital for a developer to be proficient in understanding this framework. Moreover, it allows Dot Net development companies to reduce the price of a project since the codebases can be shared.

For now let’s discover the nitty-gritty details behind choosing a proper IT supplier!
How to select a custom .Net development company?
As per the latest statistics, .Net is the world’s most used framework, with 25.2% of coders using it worldwide so finding a reliable partner is quite challenging yet accessible, and we will consider more points.
High-stakes decisions are always about conditions evaluating processes, that’s why you are here, so are we, with a material dedicated to opting for a trustworthy system integrator in a few steps that can be conducted by startups and SMEs. As we define the purpose, let’s dive right into evaluation standpoints.
— Check engineering know-how.
We have covered case studies above for each of the firms represented, so you may ask, “What else is worth investigating before signing a contract?” Here, we recommend paying attention to .NEt plus .Net Core according to the needs of your agency. Another question:
What do you do if you are not a tech guru and no one from your team is either? Just schedule a call with a provider and ask them to explain these nuances. We have described more in our article dedicated to the premier software development companies in London.
You may also need to partner with ASP Dot Net web development company (it’s outlined above in the explanation of web creation), so additionally, it’s better to ensure the dev has fullstack capability across front-end and back-end, from React to C#.
— Learn about crew composition.
There’s no need to tackle hubs that help enterprise-grade units if you need just a project that can be handled by a junior with 1 year of experience, still, it’s also a consideration if you require professionals who can handle enhanced security, data transferring, optimization, else.
— Examine development practices.
We are talking about the code again, as it’s your bread and butter, so looking over principles for creation is a must. Pioneering top .Net developers will present to you their approach to work, for example, regular code reviews, reusability skills, and manual and automated testing they implement.
— Search for unbiased referrals.
Honest insights from previous customers can become a revolutionary step in avoiding overpromises; that’s why our advice is to overview testimonials from real clients, you can do it within the posted links above, which contain portfolios, or check some independent online sources. A .Net app development company can provide some contacts for you to talk with their consumers, so feel free to ask.
Robust apps can’t be built without an adaptable and dedicated brand and even before reading this part of the article, choosing one was like climbing a greasy pole but now it’s a piece of cake.
However, we have a perspective to discuss — the price, which is as scary as a cold breath on a warm neck but can be laid out on shelves.
How much do .Net development services cost?
Based on our background of working with numerous companies, the outlined question is a steam trapped in a bottle but what if we can break it down into a table that will explain core factors and average $ of your decision to hire dedicated developers? Take a look here:
| Development | $ | Nuances |
| Custom | $10,000–$100,000+ | It can vary due to features and third-party integrations as well as the need to write a clean code from scratch. |
| Mobile app | $15,000–$130,000+ | Top .Net development companies can build an app for both Android and iOS systems which will affect the budget. |
| Web app | $15,000–$100,000+ | The final cost is determined by cross-platform support, features, flexibility. |
| Website | from $5,000 | It all depends on the number of pages, responsiveness, and mobile-first approach, so there’s no max price, on average, we can say it can lead to $100,000 and more. |
| Migration | $10,000–$160,000+ | Your data volume will determine the final cost. |
As we have considered the budget needed, let us say a few more words about estimation since it will be influenced by project complexity, senior or junior developers, tech stack, for example, if you cooperate with ASP Dot Net development company, which is more specified, and even ongoing maintenance. Hopefully, this part of the article was helpful, and we will cover more questions in our further discussion and materials.
