Good news for read (unpickle) old .net version pickled data

[ingted]

I am using a library built in .NET 9 and trying to unpickle pickle file which produced in .NET 7 library. And I use System.Runtime.Loader.AssemblyLoadContext.Default.LoadFromAssemblyPath to load the .NET 7 version library and then everything is fine now.

[ingted]

.NET 7 & 9 Version FsPickler
.NET Standard 2.0 Version FsPickler Which was built with FSharp.Core 7.0.200

Still in progress to try to resolve

[ingted]

I found a way to overcome this:

1. Create a link project reference the old version library which pickled data required to reference like this

namespace MdcFsClient70Linker //build in .net 9
type MCM7 = FAkka.TA.TAType.MyCandleMetadata //Use MCM7 to refer to .net 7 version MyCandleMetadata 

//and then MyCandleMetadata in .NET 9 project will not conflict with MCM7

2. Load old lib and the linker with this (in fsi) or directly reference it (in VS)

let alc = System.Runtime.Loader.AssemblyLoadContext.Default
let ass1 = alc.LoadFromAssemblyPath @"G:\coldfar_py\sharftrade9\mdc\MdcFsClient70Linker\MdcFsClient70Linker\bin\Debug\net7.0\MdcFsClient70Linker.dll"
let ass2 = alc.LoadFromAssemblyPath @"G:\coldfar_py\sharftrade7\mdc\MdcFsClient70_forBuild\bin3\net7.0\MdcFsClient70.dll"

3. Use MCM7 with FromBinary in .NET 9 project

let unpickled = serializerHelper.unpickle<KeyValuePair<TACategory * Set<MdcFsClient70Linker.MCM7>, SL<int64, IQuote []>>> @"G:\coldfar_py\data_pickled\20240322_ES_(((CME, ES), 30), set [Scale 30s; USING 3; MA [34M]])_ta.pickle"

ps. This assume that you could build the same project with different assembly name

Everything works like a charm now!!
