* 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.
This commit adds the `--verbosity` option to the `install tool` command.
MSBuild/NuGet output is now controllable by the user and defaults to being "quiet".
This enables users to see warnings from NuGet that otherwise would be swallowed
unless NuGet returned a non-zero exit code. As a byproduct of this change, the
exception handling and error messages related to obtaining tool packages was
retooled. We no longer display `install tool` command line help for installation
failures, as it should only be displayed for command line syntax errors.
Fixes#8465.
To ensure the mock has the same behavior the component has, run mock under the same tests the adapter has.
It is a common problem that moq has -- "everything is mocked out, you are not test anything"
