I'm trying to reproduce situation as is at this page. Db tables with generators and triggers are generated but I'm struggle with adding reference to the project inside visual studio.
FirebirdSql.Data.FirebirdClient is succ. added but when I'm try to add any of this files
fbembed.dll · icudt30.dll · icuin30.dll · icuuc30.dll
I'm getting error on adding reference like this A reference to d:....fbembded.dll could not be added. Please make sure that the file is accessible, and that is a valid assembly or COM component.
I tried with moving this files to another disk location but same thing happens.

FirebirdSql.Data.FirebirdClient, not to the other files (the screenshot confirms this) - Mark Rotteveel
