* Make dotnet install tool atomic
Apply TransactionScope to tool install. It can handle the correct timing
of roll back and commit.
Convert existing ToolPackageObtainer and ShellShimMaker by passing logic
via lambda to an object that has IEnlistmentNotification interface. It
turns out the very clean.
Use .stage as staging place to verify of package content, and shim. It
should roll back when something is wrong. When there is ctrl-c, there
will be garbage in .stage folder but not the root of the package folder.
- Created a Configurer class that is responsible for deciding when to run the dotnet first time use
experience and invoke the NuGetCachePrimer.
- Added the NuGetCachePrimer which extract the archive and primes the cache.
-- This is just missing creating the sentinel once restore succeeds.
- Added a shell for the NugetPackagesArchiver, which will be responsible for expanding the archive (likely
replaced in the future by an abstraction from Eric's code or its implementation will simply call Eric's code).
- Added a TemporaryFolder abstration to Internal Abstractions that handles deleting the temporary folder once
we are done with it.
