.NET 5 CacheHelper BinaryFormatter

[anjung]

So after the UTF-7 error is fixed it seems you are using the binaryformatter in
GetCacheDataFromObject and GetObjectFromCacheData
which unfortunatly has also been disabled in .NET 5

System.NotSupportedException: 'BinaryFormatter serialization and deserialization are disabled within this application. See https://aka.ms/binaryformatter for more information.'

public class StiRedisCache : StiCacheHelper

            _cache = cache;
        }

        public override object GetObject(string guid)
        {
            var uid = HttpContext.CoreHttpContext.User.UserId();
            var key = $"stimulsoft.{uid:D}.{guid}";

            var item = _cache.Database.StringGet(key);

            if (item == RedisValue.Null)
                return null;

            return GetObjectFromCacheData(Convert.FromBase64String(item));
        }

        public override void SaveObject(object obj, string guid)
        {
            var uid = HttpContext.CoreHttpContext.User.UserId();
            var key = $"stimulsoft.{uid:D}.{guid}";

            _cache.Database.StringSet(key, 
                Convert.ToBase64String(GetCacheDataFromObject(obj)), 
                TimeSpan.FromMinutes(10));
        }
    }

"Temporary" workaround - still please consider replacing it - and no json.net cannot replace it wirh your current "object madness"

Hello,

We need some additional time to investigate the issue, we will let you know about the result.

Thank you.

Hi,
please do as it seems the EnableUnsafeBinaryFormatterSerialization is not working as it should. (or Binaryformatter is now broken)
There is no longer an exception, but rendering small previews render alot slower and WITHOUT DATA
and larger previews just crash.

this was all working in .NET Core 3.1

for one product wich runs mostly on a single server memorycache works just fine.
Another runs on multiple servers and I do not want to rely on sticky sessions just for stimulsoft when everything else ist stateless/distributed (but may be the only solution for now)

Hello,

The issue is fixed. The fix will be available in the next release build.

Thank you.
