\"\"<\/a><\/p>\n

For testing purpose, Microsoft .NET 10 (preview version so far) is available to install in Ubuntu 22.04, Ubuntu 24.04, and 25.04 through PPA.<\/p>\n

.NET 10 is the next LTS (Long Term Support) release with 3 years of support. It’s so far in preview development stage, while the full release is expected in November 2025.<\/p>\n

<\/p>\n

What’s New in .NET 10<\/h3>\n

.NET 10 introduces significant enhancements to the JIT compiler. It improved code generation by placing struct members in registers rather than on the stack, eliminating memory accesses, and expanded devirtualize method calls to cover array interface methods.<\/p>\n

It as well improved JIT inlining, method devirtualization, and stack allocations, AVX10.2 support. And, nativeAOT’s type preinitializer now supports all variants of the conv.*<\/code> and neg<\/code> opcodes.<\/p>\n

The .NET 10 libraries introduced new APIs in cryptography, globalization, numerics, serialization, collections, diagnostics, and when working with ZIP files.<\/p>\n

It also added new JSON serialization options, and Windows Cryptography API: Next Generation (CNG) support for Post-Quantum Cryptography (PQC).<\/p>\n

For the SDK, it introduced new dnx tool execution script and added support for Microsoft.Testing.Platform in dotnet test<\/code>, platform-specific .NET tools, one-shot tool execution with dotnet tool exec<\/code>, and CLI introspection with --cli-schema<\/code>.<\/p>\n

Other changes include Blazor WebAssembly preloading, automatic memory pool eviction, enhanced form validation, and passkey support for Identity in ASP.NET Core 10.0.<\/p>\n

And, there are new features and enhancements to C# 14, F#, Visual Basic, .NET MAUI, and more. For details about the release, see the official what’s new<\/a> page.<\/p>\n

Install .NET 10 Preview from PPA<\/h3>\n

Microsoft provides official .NET 10 preview packages for Linux, Window, and macOS. They are available to download at this page<\/a>.<\/p>\n

For Linux, they are portable tarballs that contain all the executable and run-time libraries that can be run directly from terminal.<\/p>\n

For those who prefer native .deb package, Ubuntu Team maintains a PPA repository<\/a> that contains the .NET 10 preview for all current Ubuntu releases on amd64<\/code>, arm64<\/code>, ppc64el<\/code>, and s390x<\/code> platforms.<\/p>\n

To add the PPA<\/b>, press Ctrl+Alt+T<\/code> on keyboard to open terminal and run command:<\/p>\n

sudo add-apt-repository ppa:dotnet\/previews<\/pre>\n
Type user password (no asterisk feedback) when it asks and hit Enter to continue.<\/i><\/p>\n
\"\"<\/a><\/p>\n
Next, install .NET deb package<\/b> by running command:<\/p>\n
sudo apt install dotnet10<\/pre>\n
For Linux Mint, you need to run sudo apt update<\/code> first to refresh package cache.<\/i><\/p>\n
This command will install both the SDK and run-times, while you may replace dotnet10<\/code> with dotnet-sdk-10.0<\/code>, aspnetcore-runtime-10.0<\/code>, or dotnet-runtime-10.0<\/code> to install only the sdk or runtime as you prefer.<\/p>\n
\"\"<\/a><\/p>\n
If you also have .NET 8 or 9 installed on your system, then you have multiple SDK or run-times. To check them, use command:<\/p>\n
dotnet --list-runtimes && dotnet --list-sdks<\/pre>\n
Then you may choose a runtime via dotnet -r <RUNTIME_IDENTIFIER><\/code> or select SDK by using global.json<\/code> file.<\/p>\n
{\r\n      \"sdk\": {\r\n        \"version\": \"8.0.108\"\r\n      }\r\n    }<\/pre>\n
\"\"<\/a><\/p>\n
Uninstall:<\/h3>\n
To uninstall .NET 10 package installed from PPA, use command (Ctrl+Alt+T):<\/p>\n
sudo apt remove --autoremove dotnet10 aspnetcore-runtime-10.0 dotnet-runtime-10.0 dotnet-sdk-10.0<\/pre>\n
Then, remove the PPA repository either by “Software & Updates” utility under “Other Software” tab, or by running command below in terminal:<\/p>\n
sudo add-apt-repository --remove ppa:dotnet\/previews<\/pre>\n
For Linux Mint, either use Software Sources<\/code> to remove PPA, or run sudo apt update<\/code> afterward to refresh cache.<\/p>","protected":false},"excerpt":{"rendered":"
