Objects are serialized to a database using the .NET XML serializer. The object can change over time, and therefore multiple versions exist in the database at one time. Any suggestions for the best way to construct your code, so that you can still deserialize this object into the latest version. (interfaces / maps / manual serialization ...

Normally a WCF TCP channel will make a connect to a host then allow you to make method calls over it. I would like to have a service which makes outbound connections to the clients, but once the connection has been made then clients would be able to make method calls against my service as if it were a conventional connection. I suspect...

When I try to use the type, the compiler throws an error that it cannot resolve which one I want to use. I see that C# offers a mechanism to use aliases for references. You can even specify these aliases ...

I've done some searching (both here, and in general), but can't find the answers (or even reasonable hints) to what I want to achieve (though, a few things come close-ish). Basicall...
I've been told there is an environment variable you can set to force .NET applications to run as 32bit applications on x64 versions of Windows. Do you know what it is, or know of a reference on it? I'm afraid my google-fu has failed me today (or it doesn't exist). I'm using Resolver One (a .NET spreadsheet) and want to access some 32bit...
