reorg solution file

[dsyme]

This renames

.\vsintegration\src\Deployment.sln --> .\VisualFSharp.sln
Salsa.dll --> VisualFSharp.Salsa.dll
Unittests.dll --> VisualFSharp.Unittests.dll

It also

• adds a couple of virtual folders to VisualFSharp.dln (was called Deployment.sln)
• removes a couple of test files that weren't being referenced anywhere

The aim is to make it easier to contribute to the Visual F# Tools by improving the organization of things. The visual appearance of VisualFSharp.sln is shown below

maybe we can also show a clean cut between FSharp.Core (a library) and the compiler,

[dsyme]

OK done, please see below

Wow this way looks so much better! 👍

[enricosada]

Fine for me

[dsyme]

Pulling after discussing with @KevinRansom. Microsoft still has an internal build process used to package the Visual F# Tools which is separate to the process used here, and this PR might affect that because the test DLLs are being renamed. But we think that the test DLLs no longer need to be built as part of that.

In any case a big thanks to @KevinRansom in advance for dealing with any fallout of this w.r.t. the internal Microsoft build process (a pain point we hope will go away by moving to purely external build process eventually)

@dsyme why this file is deleted?

[dsyme]

This file was not included in any active testing. It's duplicated in LazyType.fs, and in any case the type is part of the .NET Fx and tested there

[enricosada]

@dsyme some test file are deleted, it's intentional (duplicated) or an error?

[dsyme]

Yes, intentional, see comments above, thanks for checking!

I just wanted to mention that I found the VisualFSharp.sln file much easier to work with this evening because of this PR - I could actually find the necessary code and the appropriate unit tests! :)

Cleanup which makes it easier to contribute is really important...
