Node.js 16 actions are deprecated. Please update the following actions to use Node.js 20: actions/checkout@v2, actions/setup-dotnet@v3, actions/cache@v2. For more information see: https://github.blog/changelog/2023-09-22-github-actions-transitioning-from-node-16-to-node-20/.

The following actions uses node12 which is deprecated and will be forced to run on node16: actions/checkout@v2, actions/cache@v2. For more info: https://github.blog/changelog/2023-06-13-github-actions-all-actions-will-run-on-node16-instead-of-node12-by-default/

The type 'TKey' cannot be used as type parameter 'TKey' in the generic type or method 'Dictionary<TKey, TValue>'. Nullability of type argument 'TKey' doesn't match 'notnull' constraint.

The type 'K' cannot be used as type parameter 'TKey' in the generic type or method 'Dictionary<TKey, TValue>'. Nullability of type argument 'K' doesn't match 'notnull' constraint.

Nullability of reference types in type of parameter 'x' of 'bool FNVByteComparison.Equals(byte[] x, byte[] y)' doesn't match implicitly implemented member 'bool IEqualityComparer<byte[]>.Equals(byte[]? x, byte[]? y)' (possibly because of nullability attributes).

Nullability of reference types in type of parameter 'y' of 'bool FNVByteComparison.Equals(byte[] x, byte[] y)' doesn't match implicitly implemented member 'bool IEqualityComparer<byte[]>.Equals(byte[]? x, byte[]? y)' (possibly because of nullability attributes).

Possible null reference argument for parameter 'other' in 'XDocument.XDocument(XDocument other)'.

Possible null reference argument for parameter 'values' in 'string string.Join(string? separator, IEnumerable<string?> values)'.

The type 'K' cannot be used as type parameter 'TKey' in the generic type or method 'Dictionary<TKey, TValue>'. Nullability of type argument 'K' doesn't match 'notnull' constraint.
