So, I'm trying the default minimal code from your example to serialize MyClass back and forward. The serialization passes, however on deserialization I've got exception cited in the title.
I just want to make sure that I understand this correctly - Do I actually need to explicitly write all the types used in MyClass structure, or write custom code which does it? That sounds insane. Why do you need that if I already gave the MyClass to Deserialize() method? Shouldn't all types used within MyClass be expected implicitly?
I understand that there are cases like having interface properties ISomething xxx where you would want me to specify that a ConcreteSomething could be used but I don't have that in my case. I have ~18 custom types used in MyClass already and I consider it a very trivial structure... Do you really want me to type typeof(XXX),... for all those types as method's parameters?

Hello, how do I deserialize a data structure in c++ that I serialized using the BinarySerializer.Serialize. Thanks

The constructor of BinarySerializationFormatter crashes in x86 projects with this exception:
AccessViolationException
Fatal error. 0xC0000005
at DynamicEnumComparerInt32`1[[KGySoft.Serialization.Binary.BinarySerializationOptions, KGySoft.CoreLibraries, Version=6.0.1.0, Culture=neutral, PublicKeyToken=b45eba277439ddfe]].ToUInt64(KGySoft.Serialization.Binary.BinarySerializationOptions)

Add this property to the csproj:
<PlatformTarget>x86</PlatformTarget>

Full Example:
KGySoftX86.zip

I have the following Situation:

I had an old .NET Framework 4.5.2 application that in the past stored the following objects serialized by the native BinaryFormatter in a SQL database:

[Serializable]
[DataContract]
public class MyClass
{
    [DataMember]
    private ConcurrentDictionary<DaylightFactorType, double[]> _values = new();
}

Now I have upgraded the application to ASP.NET 8 and when I now try to load and deserialize the data using the native BinaryFormatter, I get the following exception:

Type 'System.Collections.Concurrent.ConcurrentDictionary`2[[MyClass, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null],[System.Double[], System.Private.CoreLib, Version=8.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e]]' in Assembly 'System.Collections.Concurrent, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' is not marked as serializable.

So I thought I'd use the KGySoft.CoreLibraries to deserialize the data, because it should be possible to deserialize types that are no longer marked as [Serializable].

But the problem now is that I always get null back from the method BinarySerializer.DeserializeFromStream<T>(stream).

How can I solve this? Because the DB is actually read-only for me, and it would be a big effort to fill the database again.
