* minor changes for ValidateInput in inferencesession level api.
* update
* valid real graph input and don't validate initializers
* refine the validation logic.
* remove the unnecessary validatation test.
* ensure that the exact input feeds provided from caller.
* fix tests.
* fix c# test failure.
* fix test case
* don't verify the error message which is hard to maintain.
* fix c# test case
* c# test
* c# test
* fix test cases.
* test update
* Add ability to enable caching to the C API, and update the internals to pass the feed names and MLValue instances in vectors so the order is deterministic (so cache entry matching works as expected).
* Address PR comment and don't use 'bool'
* Remove meaningless C# test around duplicate input.
We _could_ check input names for duplicates (previously we did this via the usage of unordered_map), but the system will gracefully handle with the duplicate anyway (will just use the last value provided for the input name).
Based on that, I don't think the cost of checking for duplicates is worth it.
* Fix c-style cast in test_run_options.
* Adding initial props file updates to support native projects
