Business Software Development


There are several differences between .NET and .NET Core, such as:

  • Open-source: While the .NET core is open- source, its original .NET framework version is not.
  • Cross-platform: Your .NET Core application can run smoothly on macOS, Linux, and Windows. Meanwhile, the .NET framework apps only work on Windows.
  • Modularity: .NET Core comes with a modular architecture. On the contrary, .NET offers a more extensive set of libraries.
  • Modern Development: .NET Core is known for modern development practices, such as containerization with Docker and cloud deployment. Although .NET supports those practices, .NET Core is optimized for them.

Yes. This framework is an excellent choice for developing serverless apps using AWS Lambda or Azure Functions with custom runtimes.

The most widely used architecture patterns in .NET development are:

  • Backend: Multi-tenancy, Microservices, Serverless, CQRS, Headless (Decoupled), and DDD.
  • Frontend: MVC, Micro-frontends, MVVM, PWA, Reactive, and SPA.

You can choose the best solution for your project after considering the project requirements. It would be nice to discuss this with STS Software GmbH. Our experienced .NET developers will learn your needs and help you choose the most suitable patterns.

The cost to develop a .NET app varies from $2,000 to $25,000. It depends on multiple factors, such as:

  • Application complexity
  • Project size and scope
  • .NET development team
  • Development model

If you want to optimize your investment, we can help. Our .NET development services offer cost-effective solutions without sacrificing quality.

If you want to build simple apps, it may take two to three months. The time needed for medium apps can be from four to eight months. And if you have a plan for complex enterprise apps, you need one year or more. STS Software GmbH offers MVP development services to accelerate time-to-market. Combined with the Agile development approach, the MVP allows quicker adjustment and feedback. Ultimately, you can develop a powerful .NET app.

It depends on the hiring model. For example, if you choose the dedicated .NET development team, you will manage the project. On the other hand, if you go for full outsourcing .NET development, our project manager will be responsible for this task.
