.NET 10 can be downloaded from here. You will need the latest Visual Studio Preview to run the project with this version. Make sure to set TargetNetNext to true in the project.

To-do:

• Verify and update to make sure build files reference and install .NET 10 RC 2 explicitly (no wildcards). We want to make sure we know what SDK is used to build the binaries.
• Update any package dependencies to reference the explicit .NET 10 RC 2 package versions.
• Resolve any new analyzer warnings and errors.
• Confirm net10 binaries are created when testing locally or in the build pipeline.
• Confirm all tests pass, including .NET 10 ones.
• Check .NET 10 breaking changes for breaking changes in .NET 10 since the latest version that we use and update the code accordingly.

You can use #3287 as a reference for what changes were done to enable .NET 10 preview version.
