C#.net project files

Question

Since I am new to C#.net 2008 I have the following question to ask: Since a solution (.sln file) can have several projects in it can one project file work with another project file? In other words can 'object a' in 'project file 1' work with 'object b' in 'project file 2' by using methods in ''object b' where 'properties values' are exposed to 'pulbic' access? For example can object 'manage finances' in 'project file 1' obtain the 'checking account' values from object 'customer' in 'project file 2'? If so can you tell me and/or point me to a url that can explain how to accomplish this task? Is there a possiblity that I need to be concerned with the main method in the program.cs file for 'project file 2'?

All you need to do is add a reference to one of your other projects. Go to References - Add References... and select the Projects tab. All your other projects should be displayed. Click on OK and now you can use any of its exposed objects.

This solution is perfectly fine. Even if your other projects have their own main method only the Startup Project main method will get called when the application runs so you won't have any interference. I would suggest however that if you have multiple projects using the same objects create a seperate Class Library project to house these objects (this project will not contain the default program.cs file only your custom classes). You can then include this project instead to be referenced.

Do you think this follows good programming practices of encapsulation? Couldn't this interfere with each proejct that has it's own 'main' method and program.cs file?
