This PR documents the breaking change where Uri length limits have been removed in .NET 10 Preview 7. Previously,
Uriconstructors andTryCreatemethods limited Uri strings to around 65k characters, but these restrictions have now been lifted.The documentation includes:
/docs/core/compatibility/networking/10.0/uri-length-limits-removed.mdwith complete details about the change/docs/core/compatibility/10.0.mdThe change allows creation of
Uriinstances with much larger paths, queries, and fragments, which enables scenarios like:data:URIs containing Base64-encoded binary dataUriserves as an exchange type beyond HTTP requestsFor users relying on
Urilength restrictions for input validation, the documentation recommends implementing custom length checks before constructingUriinstances.Fixes #47602.
