Improve startup performance through lazy loading?

• After reviewing it, that does not help, yet. It refers to assemblies. Unless the game data is not wrapped into another assembly, that won't work.
• Besides, some of the data is needed rather early after the program starts (e.g. date information).

Another option would be:

• Load only those data when the app starts, that are essential for basic operations.
• Skills, ... could be loaded when a character is loaded.
• Shop data could be loaded when the shop is being opened for the first time (which is actually the case, but it is kinda hidden inside ShopInventoryViMo and not part of IGameDataService).

What I did: app won't wait for the larger data files to load immediately. Instead it keeps the Task promise and fetches the data, once it is requested.
