You should be able to upload the DLL to your host as part of the "Publish" process provided it is freely distributable and requires no licence, by including it in your BIN folder.If it requires an installation and / or a licence, then you will probably have to switch providers, and Kornfeld...

Look up database sharding. Essentially you'll have a catalog database and then shard databases (one per country). The service would wrap it up so that consumers do not need to worry about hitting the right DB.
4 Apr 2018 by Wendelius
This is an extremely good question. Few things that come in mind: If the databases are autonomous and do not need almost any information from each other, then separate database servers would probably be the easiest solution. The client application would only be configured so that it connects...

10 Oct 2015 by OriginalGriff
Not as standard - the whole idea is that it's a request / response process, so unless your client queries the server on a regular interval there is no connection so you can't tell if the server stops.You can always set a timer to do a quick check and see if it's alive?

Simplest approach - Use the concept of repeated filtering if(age == 12) { if(gender == "male") { if(grade == 2) { ... } } } You will only have as many ifs as you have attributes
