Comments on: How to use T4 to generate Decorator classes http://www.olegsych.com/2007/12/how-to-use-t4-to-generate-decorator-classes/ Interfaces are like alcohol - they are a lot of fun when used in moderation.

"Interface must be already compiled before decorator class can be generated." I'd like to avoid need to do 2 operations when I change something in interface (compile and rerun template). I'm thinking about invoking project build somewhere at the beginning of the template. Another approach can be execute template in some way from the post build action. Which approach do you think will be better or should I do something completely different? Thanks in advance for response, Marian Hi,

For example: byte[] bytes = null; using(FileStream fs = File.OpenRead("foo.dll")) { bytes = new byte[fs.Length]; fs.Read(bytes, 0, bytes.Length); } Assembly assembly = Assembly.ReflectionOnlyLoad(bytes); This *seems* to side-step the "locking" issue, but I'd love to get your thoughts on the approach.

I loop the Types for a given Namespace (from assembly.GetNamespaceList()) and then loop Members of NodeType.Property for the given TypeNode of NodeType.Class. It appears the calling Property.GetPropertyInfo() is locking the assembly with reflection. I don't see how (largely do to a lack of documentation) on how to get the info I need with a PropertyInfo object. You? I using your example to generate DTO objects based on a Model assembly.

If FxCop is installed on your build server, I don't see why you would not be allowed to use the dll. I’m not suggesting redistributing it.

Does the license of FxCop allow to use this library out of FxCop context ? (we may use it for code generation on a build server...) Thank you per advance for your response, Sylvain. Hi,

Is it possible to obtain the intellisense engine to read the properties from an interface? Your solution requires the assembly to be build which is less desirable Thanks for the information you provided.
