Node.js 16 actions are deprecated. Please update the following actions to use Node.js 20: actions/checkout@v2, actions/setup-dotnet@v1. 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/setup-dotnet@v1. For more info: https://github.blog/changelog/2023-06-13-github-actions-all-actions-will-run-on-node16-instead-of-node12-by-default/

Cannot convert null literal to non-nullable reference type.

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

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

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

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

Nullability of reference types in type of parameter 'buffer' of 'long ObjectDataReader.GetBytes(int i, long fieldOffset, byte[] buffer, int bufferoffset, int length)' doesn't match implicitly implemented member 'long IDataRecord.GetBytes(int i, long fieldOffset, byte[]? buffer, int bufferoffset, int length)' (possibly because of nullability attributes).

Nullability of reference types in type of parameter 'buffer' of 'long ObjectDataReader.GetChars(int i, long fieldoffset, char[] buffer, int bufferoffset, int length)' doesn't match implicitly implemented member 'long IDataRecord.GetChars(int i, long fieldoffset, char[]? buffer, int bufferoffset, int length)' (possibly because of nullability attributes).

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.
