Events and Jobs both have non-nullable FKs (that are also those table's PKs) pointing to CollectableEntities' PK. These FK relationships are set to cascade on update and delete. Basically, when you delete a Collecta...

I have an application which predictably generates out-of-memory errors on very, very (very) large datasets - we're trying to fix the problem by optimizing the app's memory management, but the very, very large datasets in question require so long to run (days) that it's difficult to iterate through testing cycles and find the problem empi...

Lately, I've been doing a lot of interaction with unmanaged libraries and I keep coming back to SO to ask questions about certain method signatures because I'm not a C/C++ programmer (although it's not completely alien to me). There are situations where the same type of argument in two different methods require two different P/Invoke sig...

Does anyone know if it's possible to use an ASP.NET membership (and role) provider in a non-web app (ie in a desktop C# app)? Related question -- is there an LDAP membership provider (it looks like SharePoint has one, but I don't think it's the same as the ASP.NET provider). I'm sure the Active Directory one is probably close, but I'm ...
