Performance Improvements in .NET Core 3.0

.NET Core 3 is a big change from .NET Core 2, with new workloads added to those previously supported, said Hunter, director of Program Management for .NET.

  1. High-performance implementation of .NET for creating Windows, Linux and Mac apps
    2. .NET Core 3.0 adds support for C# 8.0
    3. The .NET core 3.0 SDK comes with a tool that can reduce the deployment size of apps by analyzing IL and trimming unused assemblies and libraries.

To enable this tool, add the <PublishTrimmed> setting in your project and publish a self-contained app:


4. Tiered compilation: This feature is set to default in ASP.Net core 3.0 which is used to combines client-side and server-side compilation and enable the runtime to more adaptively use the JIT compiler for improved performance.
5. .NET Core 3.0 introduces local tools. Local tools are somewhat similar to global tools but are not available globally and are associated with a precise position on disk and are distributed as NuGet packages.

6. .NET Core 3.0 introduces an opt-in feature that allows your app to roll forward to the latest major version of .NET Core.

Project file property: RollForward
Runtime configuration file property: rollForward
Environment variable: DOTNET_ROLL_FORWARD
Command-line argument: --roll-forward

7. Improves native API interop.
8. .NET 3.0 adds support for AES-GCM and AES-CCM ciphers, implemented with System.Security.Cryptography.AesGcm and System.Security.Cryptography.AesCcm respectively.
9. .NET Core 3.0 supports the import and export of asymmetric public and private keys from standard formats. You don’t need to use an X.509 certificate.
10. For earlier versions of ASP.Net, Javascript Object Notation was a third party dependency for basic stuff. But in .NET Core 3.0, three new main JSON-related types have been added as an intrinsic supported feature. The new built-in JSON support is low allocation, high-performance, and based on Span<byte>.


Note: This is all automatic and built in with .NET Core 3.0, but if you’re targeting .NET Standard or .NET Framework. Install the System.Text.Json NuGet package (make sure to include previews and install version 4.6.0-preview6.19303.8 or higher). In order to get the integration with ASP.NET Core, you must target .NET Core 3.0.
