The behavior of 'byte.ToString(string)' could vary based on the current user's locale settings. Replace this call in 'HexEncoderTests.HexEncoderOutputIsCorrect()' with a call to 'byte.ToString(string, IFormatProvider)'.

Prefer static 'System.Security.Cryptography.SHA256.HashData' method over 'ComputeHash' (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca1850)

Remove the ToString call in order to use a strongly-typed StringBuilder overload (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca1830)

The behavior of 'int.ToString()' could vary based on the current user's locale settings. Replace this call in 'CacheHashTests.CreateLongString()' with a call to 'int.ToString(IFormatProvider)'. (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca1305)

The behavior of 'StringBuilder.AppendFormat(string, params object[])' could vary based on the current user's locale settings.
