-----------------------------------
Summary: [C#] Remove IArrowArray and use Array base class.
Key: ARROW-5546
URL: https://issues.apache.org/jira/browse/ARROW-5546
Project: Apache Arrow
Issue Type: Improvement
Components: C#
Affects Versions: 0.13.0
Reporter: Eric Erhardt
In .NET libraries, we have historically favored classes (abstract or otherwise)
over interfaces. See [Choosing Between Classes and
Interfaces|https://docs.microsoft.com/en-us/previous-versions/dotnet/netframework-4.0/ms229013(v%3dvs.100)].
The main reasoning is that you can add members to a class over time, but once
you ship an interface, it can never be changed. You can only add new interfaces.
In light of this, we should remove the IArrowArray interface, and instead just
the base `Array` class as the abstraction for all Arrow Arrays.
As part of this, we should also consider renaming `Array` because it conflicts
with the System.Array type. Instead we should consider naming it `ArrowArray`
to make it unique from the very common System.Array type in .NET.
