| Hi, I am wondering about the following line in the "Constraints" section of the "Static Class Constructors" chapter of the Managed Extensions for C Specification: A class constructor shall not directly or indirectly create any objects of its class type. How literally should this be taken? Some of my co workers take this to mean "It's OK to create an instance of a class in that class' class constru... |

| CLR and Type Constructors (2 replies) |
| microsoft.public.dotnet.framework.clr |
| On page 188 of J.Richter's Applied MSFT .NET Framework book he states ""The CLR guarantees only that a type constructor has started execution it can't guarantee that a type constructor has completed execution. This behavior was necessary to avoid deadlocks in the unusual case when two type constructors reference each other." Does this mean that instance constructors are blocked until completion or... |

I have tried to get at the stream using stdin System.Console.OpenStandardInput() and then do iasyncresult stdin.BeginRead(...), check iasyncresult.IsCompleted etc. Unfortunately, the "asynchronous" call stdin.BeginRead blocks if there is nothing to read, so I do not get the non blocking behavior.

| Performance and Dispose (7 replies) |

However, if an object has a finalizer, won't there be a performance impact of not calling dispose because the object will go from gen0 to gen1 since it's on the finalize queue? Since Dispose should call SurpressFin... |
