Every search on google and microsoft.com says that .NET was "released on November 14".. I installed 8.0.100 today and when I tried to create a new project it says "preview".
When is the real release? and how do you find out if it is release or preview without installing it? I dont see any mentioning of "preview" on the download page nor in the articles
Install the latest Visual Studio since (as it is said in the release notes):
Visual Studio Compatibility
You need Visual Studio 17.8 or later to use .NET 8.0 on Windows.
Otherwise it seems that you are running older VS version with Preview Features enabled.
November 14, 2023
The link you have provided should be enough, but here are some extra ones if you are not convinced:
Because (as it mentioned in the support policy article) it is not supported anymore:
Preview releases
The support lifecycle for applicable pre-releases is as follows.
Version Release Date End of Support .NET 8 RC2 October 10, 2023 November 14, 2023 .NET 8 RC1 September 12, 2023 October 10, 2023
Though if you scroll down the download page you will be able to see the preview and release candidates versions:
