What’s New In .Net 8.0? Everything You Should Know

Microsoft released the initial iteration of the C# language over 20 years ago. The language has had remarkable progress since its inception, when some incorrectly labeled it as a mere Java imitation, and until now, with the impending release of C# 8 with NET development services. The article discusses everything you need to know about .NET 8.0.

The new features of .NET 8.0 are the Types Of Nullable Reference, Improvements In Pattern Matching, Static Local Functions, Readonly Numbers, Null Coalescing Assignments, Asynchronous Streams, Ranges And Indices, etc.

Implementing all generator updates to employ incremental generation with the introduction of new source generators in .NET 8.0, lessening the burden of code generation on the IDE. The toolkit separates from the Windows Community Toolkit for the first time in version 8.0. Read below to learn more about .NET 8.0.

What’s New In .Net 8.0?

Here are the new features in .Net 8.0.

Types Of Nullable Reference

Nullable reference types were lastly introduced in C#. App developers can now specify in variable-type declarations whether a definition can be null to clarify their design intent.

nullable referenceNullable types can help you handle NullReference exceptions more effectively, which has been a problem for many developers. Nullable reference types are useful for both new projects and existing programs. However, null values for non-nullable values may result in a compiler warning. However, warnings one can manage by employing static null-safety analysis.

Improvements In Pattern Matching

With the latest update, C# expands the range of shape-dependent functionality that implements for various forms of data using pattern expressions.

The most significant new patterns that .NET 8.0 introduces are listed below.

  • Tuple patterns let you combine several values into a single object, making it easier to switch between them. In contrast to a basic variable, a tuple can contain arrays in addition to two or more values (up to eight).
  • Use positional patterns with a Deconstruct method to manage object properties similar to how to handle a pattern. They can be used, for instance, to identify quadrants and extract values.pattern matching
  • Property patterns are useful when you want to match an object’s properties. They can operate on types without deconstructing.
  • To return values more quickly, switch expressions and eliminate lengthy syntaxes. Switch expressions enable shorter code compared to the switch statements that have been available so far. They frequently simplify the code (given you are familiar with Lambda expressions).
  • Overall, the pattern-matching advancements made in .NET 8.0 continue those made in C# 7.0. They increase your versatility without adding complexity to the code.

Static Local Functions 

In C# 7, local functions are first introduced. You can apply a static modifier with the local function as of .NET 8.0

local function

This ensures that the static local function references no variable from the enclosing or surrounding scope. The compiler will throw an error if a static local function attempts to access the variable from the contained scope.

Readonly Numbers

The state of the instance cannot change by using readonly numbers. This means that they assist you in avoiding changing internal states when unnecessary.

readonly numbersOne of .NET 8.0‘s improvements allows you to make the intent of your code more obvious from the outset. Any structure member can add the readonly modifier to indicate that it does not change state.

Null Coalescing Assignments

Now you may check the null status of object properties by using the null-coalescing operator ??=. Further, you can assign a value to an object via null coalescing. (if it is null).

null coalescingEffective implementation focuses more on the assignment mechanism for the parameter default value. In addition, it can assist you in avoiding system issues that arise when code is simply copied and pasted without the necessary updates.

Asynchronous Streams

Asynchronous streams are now created and returned using the async modifier. .NET 8.0 allows you to wait for each stream item to finish consuming before displaying it.

asynchronousExisting iterators, which you may already be familiar with, pairs with asynchronous methods to create asynchronous streams. Writing software for the Internet of Things (IoT) or cloud-based programming applications may benefit from using asynchronous streams. 

Ranges And Indices

System.Index, which functions as an index into a sequence, and System.Range, a sequence sub-range, is the new type developing specifically for this use.

rangesMoreover, two additional operators are now available, which specify the index from the end, and.., which gives the start and stop of a range.

Interface Methods By Default

The ability to add members to interfaces using default interface methods is one of the most notable new features in .NET 8.0. Doing this allows you to add methods to SEO API even in a later version without affecting how they work with currently implemented features.

interface methodDevelopers can now securely evolve an interface without resorting to a workaround like an extension method, which has drawbacks, thanks to the new default interface methods. Clients won’t be using the new ways by default interface methods. If they so want, they can continue using the default.

What distinguishes C# versions 7 and 8?

In C# 7, local functions are first introduced. However, using a static modifier with a local function in C# 7 is impossible, meaning that static local functions are not permitted. In C# 8.0, this feature is added. You may apply a static modifier with the local function starting with C# 8.0.

Why is .NET 7 more rapid?

The tiered compilation is advantageous in .NET 7, even for methods that contain loops. By replacing the on-stack, this is accomplished. (OSR). Due to OSR, loops equips the JIT with the number of processed iterations, and the initial compilation is equipped with the number of invocations.

Is Java quicker than .NET Core?

Even though Java uses separate threads to handle and process instructions in sequences more easily, .NET 8.0 is leading in coding speed. .NET produces the same software since it is an object-oriented technology with reusable components.

What .NET framework is the most popular?

Open Source – It is an open-source platform with a straightforward installation process that provides free access to all users. Additionally, its modular architecture makes it simple to customize to your needs. A cross-platform NET Core framework can be used with multiple Linux, Windows, and macOS operating systems.

How is .NET Core faster?

It is quicker than the NET Framework because NET Core's architecture was created from the ground up to be a modular, lightweight, speedy, and cross-platform Framework. It is important to use applications like webforms, workflow, or WCF.

What is the best NET language?

NET programming is done in C#. C# is growing in acceptance as a reliable general-purpose language with a sizable user base. When looking for a great language to learn, C# is a terrific choice.


It is all about the new features of .NET 8.0. It must also satisfy the demands of developers needing help to remain relevant. It must accomplish all this while maintaining its simple and friendly object-oriented qualities. .NET 8.0, the most recent version, is the most potent C# release.
