#5: Programming Language Compatibility

C# is the primary programming language used with the Microsoft dotnet framework. If you partner with an ASP.NET development company, they will also use this language to develop your application.

With the release of .NET 8, Microsoft has also upgraded the C# programming language. It aids the developers to write clean code, helping to maintain structure, efficiently debug and update the application per business needs. In addition, the boilerplate code requirement is also eliminated with .NET 8. Further, .NET 7 doesn’t consist of these features and benefits, so .NET 8 again proved to be better.

#6: Integration

In .NET 7, integration takes more time, as developers have to create custom codes for APIs and other components. However, in .NET 8, Microsoft has provided built-in support for major integrated development environments, APIs, and services. In addition, the debugging functionalities are also advanced, helping to remove errors and improve process execution within minimal time.

After the release of .NET 8, every net development company is recommending .NET 8 to its clients. The built-in support for third-party tools, faster integrations, and upgraded C# all are making .NET 8 a better choice than .NET 7.
