Hi All! I have programmed two years in VB.Net and I'm thinking of moving on to C#. Main reason being that some applications at work are in C# and the online documentation I feel is better. I'm selflearned. My question is if you have tips regarding the problems below, documentation or tutorials that helped you once upon a time. Now to the problems: 1. I'm having difficulties to grasp how my new projects structure internally would be, best case. Often I start programming and finding out as I go. I feel I'm having planning issues. I work alot with database access applications. 2. When I'm programming I feel that I have a problem with finding good object structure. Per say; I have a class that handles errormessages but I have trouble seeing the solution for the structure of it and how other classes should us this class. 3. I work alot with databases, SQLite, Access etc. I've been reading into Dapper-solutions for easy CRUD work. Somehow I feel I should start of more basic. 4. I lack some basic OOP understanding. Even if I've read alot I feel I cannot implement it. For example interfaces, inheritence and project patterns. Examples I've read is relatade to real-time objects as Cats, Cars etc. But when I have for example "Register an abscense / holiday" etc. How should that object look and fall in line with other objects, no clue... Any tips on either number is greatly apprieciated! H
