Nullability of reference types in type of parameter 'buffer' of 'long CareSiteDataReader.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 CareSiteDataReader.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).

Nullability of reference types in type of parameter 'other' of 'bool SourceConcepts.Equals(SourceConcepts other)' doesn't match implicitly implemented member 'bool IEquatable<SourceConcepts>.Equals(SourceConcepts? other)' (possibly because of nullability attributes).

Nullability of reference types in type of parameter 'buffer' of 'long ChunkDataReader.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 ChunkDataReader.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).

Nullability of reference types in type of parameter 'other' of 'bool LookupValue.Equals(LookupValue other)' doesn't match implicitly implemented member 'bool IEquatable<LookupValue>.Equals(LookupValue? other)' (possibly because of nullability attributes).

Nullability of reference types in type of parameter 'buffer' of 'long CareSiteDataReader.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 CareSiteDataReader.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.
