Nullability of reference types in type of parameter 'keyOrPrefix' of 'IEnumerable<(byte[] Key, byte[] Value)> MemoryStore.Seek(byte[] keyOrPrefix, SeekDirection direction = SeekDirection.Forward)' doesn't match implicitly implemented member 'IEnumerable<(byte[] Key, byte[] Value)> IReadOnlyStore.Seek(byte[]? keyOrPrefix, SeekDirection direction)' (possibly because of nullability attributes).

Possible null reference assignment.

Possible null reference argument for parameter 'item1' in '(byte[], byte[]).ValueTuple(byte[] item1, byte[] item2)'.

Possible null reference argument for parameter 'item2' in '(byte[], byte[]).ValueTuple(byte[] item1, byte[] item2)'.

Possible null reference argument for parameter 'item1' in '(byte[], byte[]).ValueTuple(byte[] item1, byte[] item2)'.

Possible null reference argument for parameter 'item2' in '(byte[], byte[]).ValueTuple(byte[] item1, byte[] item2)'.

Possible null reference argument for parameter 'address' in 'UInt160 Helper.ToScriptHash(string address, byte version)'.

Method 'TestingPlatformEntryPoint.Main(string[])' will not be used as an entry point because a synchronous entry point 'Program.Main(string[])' was found.
