I am getting "Cannot serialized the aspects: Type 'log4net.Core.LogImpl' in assembly 'log4net...'" -how can I make it serializable?
.net, c#, log4net, postsharp
Solution
Based on the comments from Grant and mtsiakiris I solved this problem by adding the `[NonSerialized]` attribute to the field like this:
[NonSerialized]
ILog _logger = LogManager.GetLogger("MethodBoundaryAspect");
which then just ignored it during serialization. The reason this occurs is because PostSharp needs to serialize the attribute during its IL generation.
Problem
Environment - Windows 7 x64 - PostSharp 2.1.7.30 installed - PostSharp 2.1.7.29 (reference retrieved from the PostSharp install directory) - log4net 1.2.11.0 (reference retrieved from the `net\2.0\release` directory of the log4net binaries download) - ASP.NET 2.0 application - Visual Studio 2010 SP1 Aspect ``` [Serializable] public class MethodBoundaryAspect : PostSharp.Aspects.OnMethodBoundaryAspect { ILog _logger = LogManager.GetLogger("MethodBoundaryAspect"); public override void OnEntry(PostSharp.Aspects.MethodExecutionArgs args) { _logger.DebugFormat("The user {0} entered the method {1} at {2}.", HttpContext.Current.Profile.UserName, args.Method.Name, DateTime.Now); base.OnEntry(args); } public override void OnExit(PostSharp.Aspects.MethodExecutionArgs args) { _logger.DebugFormat("The user {0} exited the method {1} at {2}.", HttpContext.Current.Profile.UserName, args.Method.Name, DateTime.Now); base.OnExit(args); } public override void OnException(PostSharp.Aspects.MethodExecutionArgs args) { _logger.DebugFormat("The user {0} was executing the method {1} when an unhandled exception occurred at {2}.{3}{4}", HttpContext.Current.Profile.UserName, args.Method.Name, DateTime.Now, Environment.NewLine, args.Exception.ToString()); base.OnException(args); } } ``` Compile Error Cannot serialize the aspects: Type 'log4net.Core.LogImpl' in Assembly 'log4net, Version=1.2.11.0, Culture=neutral, PublicKeyToken=669e0ddf0bb1aa2a' is not marked as serializable. How can I make the `log4net.Core.LogImpl` serializable so that I can compile this solution?
