Download .NET 7 Preview 5 (Offline Installers)

Subhan Zafar|August 29, 2022

.NET 7 Preview 5 has now been released for the developers to test out before the actual, stable .NET 7 is released. With each iteration, new features, support, and improvements are added so that when the stable version comes out, the developers already know what to expect.

With Preview 5, Microsoft has only focused on a feature known as “Generic Math.” This feature was first released with .NET 6. Since then, Microsoft has been continuously working on this feature to enhance it and make improvements.

You can download and install .NET 7 Preview 5 on your compatible devices using the direct download links shared below. .NET 7 can be installed on the following platforms:

Windows
Linux
MacOS

.NET 7 Preview 5 has been tested with Visual Studio 17.3 Preview 2, thus Microsoft recommends that you use it with preview channel releases of Visual Studio only to avoid compatibility conflicts.

Let us now dig into the new improvements this release has to offer before you download and test it out.

New in .NET 7 Preview 5

Generic Math

Generic Math combines the power of generics and a new feature known as “Static virtuals in interfaces” to allow the .NET developers to take advantage of static APIs, including operators, from generic code.

Developers now no longer need to write or maintain almost-identical implementations to support multiple number-like types. Instead, you can now use the power of generics with the ability to constrain the input to types.

You now get access to all your favorite operators like static T Add(T left, T right) where T : INumber => left + right;, which was previously impossible to define. You can use these operators from generic contexts.

To learn more about the Generic Math feature, refer to this Microsoft guide post.

Improvements to Observability

A series of improvements have been made to support observability in .NET 7 since the last few flights. Microsoft has also made a new improvement to observability in .NET 7 Preview 5 as well.

You can now expose performant ActivityEvent and ActivityLink to enumerate the Tag objects without any extra allocations and fast items access.

Polymorphism

The support for serializing and deserializing polymorphic type hierarchies has been added to the System.Text.Json. This can be done using attribute annotations. Here is an example from Microsoft:

[JsonDerivedType(typeof(Derived))]
public class Base
{
    public int X { get; set; }
}

public class Derived : Base
{
    public int Y { get; set; }
}

Other Breaking Changes

Some other significant changes since the release of .NET 6 include the following:

System.IParseable has been renamed to System.IParsable.
All the other new numeric interfaces have been moved to the System.Numerics namespace.

Introducing INumberBase so that types like System.Numerics.Complex can be represented.
Splitting the IEEE 754 specific APIs into their own IFloatingPointIeee754 interface so types like System.Decimal can be represented.
Moving various APIs lower in the type hierarchy such as the IsNaN or MaxNumber APIs:
- Many of the concepts will return a constant value or be a no-op on various types.
- Despite this, it is still important that they’re available since the exact type of a generic is unknown and many of these concepts are important for more general algorithms.

The list does not end here. To read about what other changes have been made to .NET, read this Microsoft post.

Closing Words

.NET 7 Preview 5 focuses primarily on one feature which is “Generic Math.” After reviewing the detailed release notes, we can conclude that there is a plethora of new features and support inside the update. However, the developers may need a learning curve to familiarize themselves with all Generic Math, as well as the other improvements, have to offer.

This is why we recommend to our .NET developers to test out .NET 7 Preview 5 on their testing environment and get to see the live-action of the new functionalities and operations.
