HI,
[quote user="HDR_Coder"]I've discovered that in order to load/unload C# applications I must[/quote]
Not sure if I remember older discussions about loading addins to own domain well, but I guess it's not supported officially, regardles the key-in is available.
The problem I recall is that (at least in V8i) some addins don't work or work unpredicateble, because their code or used API don't expect they will be run not in MicroStation default domain.
So I guess you can use it e.g. during coding and testing, but any production and officialy supported installation should not use it. But maybe somebody from Bentley will provide more detail insight and explanation.
[quote user="HDR_Coder"]I would prefer to load my apps from a directory for the sake of organization. [/quote]
It's not quite clear where the problem is. C# addins can be placed in any folder (contrary to V8i, also in network places, because NET 4 changed security rules and implementation) as long as the folders are defined in MS_ADDINPATH variable (in some situations also MS_ADDIN_DEPENDENCYPATH should be configured accordingly).
With regards,
Jan
