Research direction
No implementation file, test, or entry point is named. Start by reviewing the proposed implicit operators and the existing KeyValuePair and ValueTuple APIs in the .NET runtime. Done would require an accepted API design plus implementation and tests covering conversions in both directions.

Description
Summary
It would be beneficial to add implicit conversion support between KeyValuePair<TKey, TValue> and ValueTuple<TKey, TValue> in the .NET runtime. This would allow for more seamless interoperability between APIs and code that use these types interchangeably.
Rationale
KeyValuePair<TKey, TValue>and(TKey, TValue)are often used in similar scenarios, such as returning pairs from methods or working with collections.- Adding implicit conversion would reduce the need for explicit conversions and make code more concise and readable.
- It would align with the trend towards more tuple-friendly APIs in modern .NET.
Proposed API
public static implicit operator (TKey Key, TValue Value)(KeyValuePair<TKey, TValue> pair);
public static implicit operator KeyValuePair<TKey, TValue>((TKey Key, TValue Value) tuple);
Alternatives
- Use extension operators to convert.
