| Do I need to worry about dependency on runtime version? (4 replies) |
| microsoft.public.dotnet.faqs |
| Hi. When we write our class libraries, are we tied to a particular version of the run time? If so, does that mean, when we deploy our class libraries, we should also deploy the runtime that we built with? It doesn't make sense though because if that's the case, then the customers would potentially have so many versions of the .NET runtime after they install different .NET components/libraries from... |

| microsoft.public.dotnet.faqs |

Afterall, from what the concept goes, each Win32 physical process can contain multiple AppDomains, which in .NET terms, is a logical process. And not only that, each AppDomain can contain multiple threads that are, again, logical in nature. So, the question I had always been pondering upon was how these "logi... |

How do I tell what version of the .NET framework ASP.NET is running against?
