The dotnet '10.0' option currently points to the '10.0-preview' version of dotnet. The dotnet '10.0' stable version is expected to be released by end of 2025. The preview version is still under development and is generally not supported for production use.

Should we change it to 10.0-preview?

Hello @eljog ,

The url https://builds.dotnet.microsoft.com/dotnet/Sdk/ used in dotnet feature to download the installation package, expects this version 10 to be passed on as 10.0 in the same way like other versions. The only way to label it as preview version would be possible if the exact version is provided like 10.0.100-preview.3.25201.16.

Whereas in case of the dotnet devcontainer image, the base image is downloaded from mcr.microsoft.com/dotnet/ registry where the dotnet 10 versions are actuality labeled as 10.0-preview for e.g. mcr.microsoft.com/dotnet/sdk:10.0-preview-trixie-slim. Thats why it was possible there to label the version as 10.0-preview for the image.

So in case of the dotnet feature if we want to change the version from 10.0 to 10.0-preview, we will need a small customization in the feature to remove the preview part from the version parameter & use it in the script. Kindly let me know if we should do something like that for this PR.

With Regards,
Kaniska

Hello @eljog ,

As discussed, I have added comments to point out the dotnet 10.0 version offered is basically 10.0-preview version which marks it to be under development & its not recommended for production use. Would you kindly review the same.

With Regards,
Kaniska
