## Validation Steps Performed
* Change to use App CRT in preparation for universal.
* Try to make project build again by setting winconpty to static lib so it'll use the CRT inside TerminalConnection (or its other consumers) instead of linking its own.
* Remove test for conpty dll, it's a lib now. Add additional commentary on how CRT linking works for future reference. I'm sure this will come up again.
* use the _apiset variant until proven otherwise to match the existing one.
* Clarification in the comments for linking.
This commit cleans up and deduplicates all of the common build
preamble/postamble across exe, dll, lib and c++/winrt projects.
The following specific changes have been made:
* All projects now define their ConfigurationType
* All projects now set all their properties *before* including a common
build file (or any other build files)
* cppwinrt.pre and cppwinrt.post now delegate most of their
configuration to common.pre and common.post
* (becuase of the above,) all build options are conserved between
console and c++/winrt components, including specific warnings and
preprocessor definitions.
* More properties that are configurable per-project are now
conditioned so the common props don't override them.
* The exe, dll, exe.or.dll, and lib postincludes have been merged into
pre or post and switched based on condition as required
* Shared items (-shared, -common) are now explicitly vcxitems instead of
vcxproj files.
* The link line is now manipulated after Microsoft.Cpp sets it, so the
libraries we specify "win". All console things link first against
onecore_apiset.lib.
* Fix all compilation errors caused by build unification
* Move CascadiaPackage's resources into a separate item file
Fixes#922.
The WAP packaging project in VS <= 16.3.7 produces a couple global
properties as part of its normal operation that cause MSBuild to flag
our projects as out-of-date and requiring a rebuild. By forcing those
properties to match the WAP values, we can get consistent builds.
One of those properties, however, is "GenerateAppxPackageOnBuild", and
WAP sets it to *false*. When we set that, of course, we don't get an
MSIX out of our build pipeline. Therefore, we have to break our build
into two phases -- build, then package.
This required us to change our approach to PCH deletion. A project
without a PCH is *also* considered out-of-date. Now, we keep all PCH
files but truncate them to 0 bytes.
TerminalApp, however, is re-linked during packaging because the Xaml
compiler emits a new generated C++ file on every build. We have to keep
those PCHs around.
* Remove WpfTerminalControl AnyCPU from Arch-specific builds
This removes another source of build nondeterminism: that WpfTerminalControl was propagating TargetFramework into architecture-specific C++ builds. Its "Any CPU" platform has been removed from architecture builds at the solution level.
This also cleans up some new projects that were added and build for "Any
CPU".
* Cleanup PCHs as the build rolls along to leave enough space on CI agents.
* Attempt to restrict pch cleanup to only CI agents.
* Write message when objects are deleted.
