I just rebuilt my computer and now I am getting this error in one of my apps when I try to run it. I have tried deleting and regening the class and still get the problem any ideas? Exact error: An unhandled exception of type 'System.MissingMethodException' occurred in sd.llblgen.pro.dqe.sqlserver.net11.dll

Additional information: Method not found: Void SD.LLBLGen.Pro.ORMSupportClasses.TraceHelper.WriteLineIf(Boolean, System.String, System.String).

Stack trace:

10 to 1 it's because you build against the .NET 1.0 version of the runtime libs.

Not really sure what you mean. I deleted the DAL project, regenerated and compiled it. The sd.llblgen.pro.dqe.sqlserver.net11.dll is the referenced assembly in the DAL project. Not sure what else could be wrong? I am sure that it is something stupid but I cannot seem to track it down

Also the ormsupport classes are the .net 11 versions? Could you also check they're both of the same runtime pack? (e.g.: not al old dqe and a new ormsupportclasses dll for example) ?

Method not found errors come from the fact that the dll referenced at compile time, isn't the one used at runtime.

must have been an old assemblie somewhere. I deleted all the bin directories / recompiled and it worked!
