IncludeFileNamesCollector doesn't work cross-platform

[jmezach]

I've been working on an open source project called MSBuild.Sdk.SqlProj which allows defining SSDT like projects using the simplified SDK-style project files while also enabling support for building .dacpac's cross-platform.

One of the things that has been requested is support for merging pre- and/or post-deployment scripts into a single file (see jmezach/MSBuild.Sdk.SqlProj#23), which can then be packaged into the resulting .dacpac. I've looked at how this works in Visual Studio and that seems to rely on the IncludeFileNamesCollector from the Microsoft.Data.Tools.Schema.Sql.Deployment namespace in the Microsoft.Data.Tools.Schema.Sql assembly. This type parses the SQL scripts and resolves imported scripts (using the :r OtherScript.sql syntax), which is exactly what I need.

Now I know that this is an internal type, but I'd rather not re-invent the wheel so I'm using reflection to use it. However, I'm running into an issue where this type is normalizing paths to be all uppercase. That works just fine on Windows of course, but not so much on operating systems that have a case sensitive file systems (like Linux).

Not sure if this is the right place, but I'm wondering if there's something that can be done here so that I can unblock my users. The assembly I'm using is part of the Microsoft.SqlServer.DACFX NuGet package.
