[WIP] Port ConvertSwitchStatementToExpression analyzer/fixer to shared layer #41815

mavasani · 2020-02-20T15:18:04Z

Extracted out of #41363 so it only contains the following changes:

Port analyzer/fixer/test files for ConvertSwitchStatementToExpression to shared layer
Options related namespace changes (see comment Port few IDE analyzers/fixers to shared layer to be enabled in CodeStyle NuGet package #41363 (comment) for details)
MEF based language service discovery in CodeStyle layer. Follow up items after PR 41363 #41462 tracks replacing this with a non-MEF based approach.
Minimal resx/xlf file changes - few were needed as the resources used by analyzer/fixer were moved to shared resx file.
Enable .editorconfig based unit test support for CodeStyle layer. NOTE: First commit b006324 just ports changes from Always try to register the EditorConfigDocumentOptionsProvider #40513 which are required to enable this support. This commit should become redundant once that PR is merged in.

why is all this changing?

this feels very hacky.

i have to admit this is getting very confusing.

i also don't like all the duplication in the code below... is this all realy necessary?

i really don't like how infectious this seems to be. it feels like we're becoming a c++ codebase with ifdefs everywhere to support conditional compilation.

like... this literally feels like entirely separate approaches here. having us use ifdefs instead of other mechanisms (i.e. interfaces/DI/etc.) just feels really hacky and hard to maintain.

this is super confusing to read and understand. i also just am hating the ifdef shenanigans.

@CyrusNajmabadi Please hold off reviewing this PR for now. @sharwell is changing options infrastructure to avoid requiring any conditional preprocessor directives in shared layer.
