Updated assertions in Test_RelayCommandAttribute_WithPartialCommandMethodDefinitions to assign results to the discard variable, improving code clarity and suppressing possible warnings about unused return values.
Replaces usages of Assert.AreEqual, Assert.IsTrue, and similar assertions with new helper methods such as Assert.HasCount, Assert.IsEmpty, Assert.IsNull, and Assert.IsGreaterThanOrEqualTo across multiple test files. This improves test readability and consistency with updated assertion APIs.
Updated all unit tests to consistently use the expected value as the first argument in Assert.AreEqual calls. This improves readability and aligns with best practices for test assertions.
