SOE and SOI developed with Enterprise sdk always are ok after last ArcGIS Enterprise 10.9.x, part of the ArcGIS 2021 releases. You cannot use SOE and SOI developed with ArcObjects .NET/Java SDK in version released after last ArcGIS Enterprise 10.9.x, part of the ArcGIS 2021 releases  because the ArcGIS 2022 releases of ArcGIS Enterprise will only contain the ArcGIS Pro-based runtime Removal of ArcMap-based runtime from ArcGIS Enterprise (esri.com)   ...

Ciao Gianni, The FeatureCollection is an encoding of feature geographic and attribute data structures using the Protocol Binary Format (PBF). Notably, the FeatureCollection is an alternative encoding of a FeatureSet, ESRI's JSON encoding of Feature objects. Not only are FeatureCollections serialized differently through the use of a new binary specification, but they also have fundamental structural differences that developers will need to account for. here you can see the initial specification arcgis-pbf/proto/FeatureCollection at main · Esri/arcgis-pbf · GitHub you can generate your class in for example c# protoc.exe FeatureCollection.proto --csharp_out=C:/Temp/Scratch/out --proto_path=c:/Temp/Scratch/pbf you can download protoc.exe here Release Protocol Buffers v3.17.2 · protocolbuffers/protobuf · GitHub FeatureCollection.proto  ( https://raw.githubusercontent.com/Esri/arcgis-pbf/main/proto/FeatureCollection/FeatureCollection.proto ) then with your class generated you can write similar code to deserialize pbf:   FeatureCollectionPBuffer f = (File.ReadAllBytes(@"C:\Temp\Scratch\pbf\query")).ToObject<FeatureCollectionPBuffer>(); public static T ToObject<T>(this byte[] buf) where T : IMessage<T>, new() { if (buf == null) return default(T); using (MemoryStream ms = new MemoryStream()) { ms.Write(buf, 0, buf.Length); ms.Seek(0, SeekOrigin.Begin); MessageParser<T> parser = new MessageParser<T>(() => new T()); return parser.ParseFrom(ms); } }           ...

In help you need see class that implement the interface IFeatureClassName You can write similar code: IMapServer mapServer = (IMapServer)serverObjectHelper.ServerObject; string mapName = mapServer.DefaultMapName; IMapServerDataAccess dataAccess = (IMapServerDataAccess)mapServer; IFeatureClass sourceFeatureClass = (IFeatureClass)dataAccess.GetDataSource(mapName, 0); IDataset sourceDataSet = (IDataset)sourceFeatureClass; IWorkspace sourceWorkspace = sourceDataSet.Workspace; IFeatureDataConverter featureDataConverter = new FeatureDataConverterClass(); IWorkspaceFactory targetWorkspaceFactory = new ShapefileWorkspaceFactory(); IWorkspace targetWorkspace = targetWorkspaceFactory.OpenFromFile($@"c:\temp", 0); IDataset targetWorkspaceDataset = (IDataset)targetWorkspace; IName targetWorkspaceDatasetName = targetWorkspaceDataset.FullName; IWorkspaceName targetWorkspaceName = (IWorkspaceName)targetWorkspaceDatasetName; IFeatureClassName shpFeatureClassName = new FeatureQueryNameClass(); IDatasetName shpDatasetName = (IDatasetName)shpFeatureClassName; shpDatasetName.WorkspaceName = targetWorkspaceName; shpDatasetName.Name = $"Test_{Guid.NewGuid()}"; int shapeFieldPosition = sourceFeatureClass.FindField(sourceFeatureClass.ShapeFieldName); IFields inputFields = sourceFeatureClass.Fields; IField shapeField = inputFields.get_Field(shapeFieldPosition); IGeometryDef geometryDef = (IGeometryDef)((IClone)shapeField.GeometryDef).Clone(); IFields outFields = (IFields)((IClone)sourceFeatureClass.Fields).Clone(); featureDataConverter.ConvertFeatureClass((IFeatureClassName)sourceDataSet.FullName, null, null, shpFeatureClassName, geometryDef, outFields, "", 1000, 0);   ...
