.NET 7.0 offers the following features and benefits.
Runtime and framework libraries
.NET consists of the runtime and the framework libraries as well as compilers, build tools, tools to fetch NuGet packages, and a command-line interface to tie everything together. Benefits include:
- Automatic memory management
- Type safety
- Delegates and lambdas
- Generic types
- Language Integrated Query (LINQ)
- Async programming
- Native interoperability
- Source generators
.NET 7.0 supports developing applications using ASP.NET Core 7.0 and EF Core 7.0, which bring benefits such as:
- Lightweight and modular HTTP request pipeline
- Ability to host on a web server or self-host in your own process
- Built on .NET, which supports true side-by-side app versioning
- Integrated support for creating and using NuGet packages
- Single aligned web stack for web UI and web APIs
- Cloud-ready environment-based configuration
- Built-in support for dependency injection
- Tools that simplify modern web development

.NET 7.0 continues to broaden its support and tools for application development in an open source environment. The latest version of .NET includes the following improvements:
-
IBM Power support: In addition to the
x64_64(64-bit Intel/AMD),aarch64(64-bit ARM) ands390x(64-bit IBM Z) architectures, .NET 7.0 introduces support for theppc64le(64-bit IBM Power) architecture on RHEL 8.7 and later and RHEL 9.1 and later. - C# updated to C#11: Includes new language versions C# 11.
- Support for building completely native console applications.
- Performance improvements: Many performance improvements were made throughout the base libraries, GC, and JIT. A new source generator for regular expressions eliminates the cost of compiling (or interpreting) regular expressions at run-time.
- New APIs and improved monitoring: Improved support for OpenTelemetry. .NET 7.0 comes with new APIs for working with tar files and Unix file permissions.
- Generic Math: Allows writing generic algorithms that work against any of the built-in numeric types, and enables building your own numeric types.
- ASP.NET Core 7 improvements: Improves the performance of HTTP/2 and HTTP/3. Also extends the minimal APIs, introduced in .NET 6, with additional OpenAPI support, endpoint filters, and route groups.
