I am using rider but some reasons I can't see any option to create web-related projects with F#.
I even installed the Girafe template but I still don't see anything in the project creation panel.
is there anything I can do to projec templates with F# in Rider?
Unfortunately Rider does not support these web templates. I mean we have disabled them intentionally in the Rider's source code ~ 2 years ago:
// HACK: Do not show F# web templates
if (info.GroupIdentity.StartsWith("Microsoft.Web") && info.GetTagValue(LanguageGroupProvider.LanguageTag) == "F#") continue;
In 2019.2 (the next release) we will enable them because for know all known issues with F# and web were fixed. We just forgot to enable templates.
I can suggest to use dotnet
command line for now. Sorry for inconvenience.
