POProtobuf-Net fails on Monodroid with InvalidOperationException in release mode
text
Body
copied!<p>Building a Monodroid application we've been using Protobuf-net for serialization. It works in debug mode when fast deply is turned on, however once we switch to release mode it fails with the following exception:</p> <pre><code>ex {System.InvalidOperationException: Cannot serialize property without a get accessor at ProtoBuf.Serializers.PropertyDecorator.SanityCheck (System.Reflection.PropertyInfo property, IProtoSerializer tail, System.Boolean& writeValue, Boolean nonPublic) [0x00000] in <filename unknown>:0 at ProtoBuf.Serializers.PropertyDecorator..ctor (System.Type forType, System.Reflection.PropertyInfo property, IProtoSerializer tail) [0x00000] in <filename unknown>:0 at ProtoBuf.Meta.ValueMember.BuildSerializer () [0x00000] in <filename unknown>:0 at ProtoBuf.Meta.ValueMember.get_Serializer () [0x00000] in <filename unknown>:0 at ProtoBuf.Meta.MetaType.BuildSerializer () [0x00000] in <filename unknown>:0 at ProtoBuf.Meta.MetaType.get_Serializer () [0x00000] in <filename unknown>:0 at ProtoBuf.Meta.RuntimeTypeModel.Serialize (Int32 key, System.Object value, ProtoBuf.ProtoWriter dest) [0x00000] in <filename unknown>:0 at ProtoBuf.Meta.TypeModel.SerializeCore (ProtoBuf.ProtoWriter writer, System.Object value) [0x00000] in <filename unknown>:0 at ProtoBuf.Meta.TypeModel.Serialize (System.IO.Stream dest, System.Object value, ProtoBuf.SerializationContext context) [0x00000] in <filename unknown>:0 at ProtoBuf.Meta.TypeModel.Serialize (System.IO.Stream dest, System.Object value) [0x00000] in <filename unknown>:0 at ProtoBuf.Serializer.Serialize[UltraliteJCommandParameters] (System.IO.Stream destination, Company.Product.ProtocolBuffers.Android.UltraliteJCommandParameters instance) [0x00000] in <filename unknown>:0 at Company.Product.UltraliteJ.DataCommand.SerializeParameters () [0x00261] in C:\DevSVN\Product\FS\Trunk\FSAndroidSolution\Company.Product.UltraliteJ\DataCommand.cs:109 at Company.Product.UltraliteJ.DataCommand.LoadValue () [0x00001] in C:\DevSVN\Product\FS\Trunk\FSAndroidSolution\Company.Product.UltraliteJ\DataCommand.cs:44 at Company.Product.Ultralite.Controlers.UltraliteDataServer.RunUpgradeScripts (System.String version, Boolean syncSuccessful) [0x0007e] in C:\DevSVN\Product\FS\Trunk\Company.Product.Ultralite.Controlers\UltraliteDataServer.cs:375 } System.InvalidOperationException </code></pre> <p>We are using the generated code from a .proto file, and it works in debug mode.
