Uri.TryCreate Returns True For Uris That Are Not Absolute - Linux #108221

Closed ashleyjlive closed 1 month ago

ashleyjlive commented 1 month ago

Description

After migrating our application tests from a Windows based build agent to a Linux based build agent we noticed that Uri.TryCreate has different behaviour. On Linux, Uri.TryCreate("/foo", UriKind.Absolute, out var uri) returns true whereas on Windows it returns false. I believe the behaviour on Linux is incorrect.

Reproduction Steps

Execute Uri.TryCreate("/foo", UriKind.Absolute, out var uri) on a Linux machine. Its output will be true whereas on Windows it is false.

Expected behavior

It should return false.

Actual behavior

It returns true.

This is a duplicate of https://github.com/dotnet/runtime/issues/80118 and https://github.com/dotnet/runtime/issues/76816.

See those issues for an explanation of why this is expected behavior.

Closing as (unfortunately) by design as per above info.
