Fix namespace for current document

[giggio]

If a file is located at:
$solutionDir\$projectDir\Folder1\Folder2\file.cs
And the root namespace is Project then the namespace for the file should be Project.Folder1.Folder2.

I have been trying to work this issue, but I do not yet know where to start, as I can't seem to find the Default Namespace setting in the Roslyn APIs. I will follow up with the C# team, if I find something about it I will continue. @ElemarJR @viniciushana @carloscds any idea on how to move this forward?

[carloscds]

I think that is not wasy to solve this, because Namespace can be anything, not properly a list of files.

[sharwell]

This should be co-implemented with an alternative code fix to move the file to the correct location reflecting the namespace. This feature is closely related to DotNetAnalyzers/Proposals#13.

@carloscds told me he is working on it now. He said he solved the file location problem. I can't wait to see it.

[carloscds]

@giggio Now it´s working, but I need help to write test. Maybe we need to change some tests methods.

[giggio]

I am reopening the issue, as we still need to progress on the issue. Also, see PR #38.

[giggio]

We still have work to do here, one idea may be to watch the csproj/kproj and get the information from there. Not giving up on this one yet.

@giggio You can't read file from analyzer because it's a PCL.I have write this in issue PR #38, and according to Microsoft is not a good idea change PCL to a normal class library. But if you can try...

[giggio]

We can use System.IO to read the file. I am not sure about FileSystemWatcher, though.

[carloscds]

@giggio System.IO is partially support by PCL. I have a complete code for this, but when I put into analyzer, my code breaks because PCL doesn't implement System.IO.Directory

[giggio]

We would need to read a file, parse it, and find the default namespace. If we can add a FileSystemWatcher to refresh it when the file changes than it is better. We don't need the Directory class.

[carloscds]

You need read file and find RootNameSpace. As I tell, I have create this code that get some source file in project identity your csproj (check if this source is part of this csproj) and after this get RootNamespace. I'm curious about how FileSysteWatcher can identity correct csproj file in a complex solution.
If you solve this (identity csproj anbd read rootnamespace)we have another fix, because it is my orrent problem.
