Hi I am a CS student turning into a sophomore! So I don't have extensive knowledge.

I want to make a web service that can hold data and retain it. Any suggestions? I need to have a list with a bunch of list names and each list name has a LinkedList of strings. Any idea of what kind of web service I should go for? I am using Visual Studio 2010. I don't know which .NET framework I should work on, because I want to make a class library that uses the web service, and the class library would be visable to Visual Studio 6. I have been looking at COM Interop stuff. But I need to decide which web service go first!

Why would you want to use Linked Lists. You just need to create a static cache using List<string> or Collection<string>...
These cache items will be deleted if the web service is restarted, so you would be best off to create a simple database to hold the values and then just use the service to act as a data manager between your calling applications and the database.

Good points, my 5
You were at least honest and upfront saying your a student so I'll take it this is a homework assignment.

It doesn't matter what version of the .NET framework but since you are using VS2010 it might as well be 4.0.

A webservice itself doesn't retain data. The data needs to be persisted somewhere, usually a database.

LinkedList<T>[^]

Remember your professor is probably monitoring this, and other sites, to see who does the work own their own and who asks for others to do it for them.

Hahaha it's not a homework assignment. Self-learning kind of.
A web service doesn't hold the data. It provides read and/or write access to it. the data itself is stored in some sort of data medium, usually a database, but sometimes a flat file.

If you want to use interop, you should create a .Net assembly that communicates with the web service, and then transfers the data it receives to the unmanaged C++ app.

If you want my honest opinion, you've bitten off more than you can chew, and you should do something a bit simpler. After all, you're just a sophomore.

would you recommend an SQL Server Database or a flat file for quick message adding and deleting from these files?

If you have the option of a database, I would use it. It will allow you to build out more in the future.

SQL Express is free, and it will allow you build upward.
