Question

Answer 1

You may want to look at .Net Interop.

Also take a look at West-Wind web connect. They have a framework that allows you to use the Visual studio IDE to create webforms but also use your VFP business logic and data source. This works well.

West wind also has a wwDotNetBridge that allows you to access .Net components from VFP.

Check out their website below.

Answer 2

I don't think you necessarily need to go the way of "interop", but get a basic understanding of connecting and querying data.

First, get Microsoft's OleDB provider located here

Here is a sample doing a connection and running a simple query to get data but this one sends the results to another VFP table instead of bringing back to C# for process/usage.

This example shows Inserting records and uses parameters to help prevent any attempts at SQL-injection attacks

And another using SQL-Update

Once you get the basics down, its not that difficult. I've actually made a simple "wrapper" class to centralize ensuring a valid connection, execute a given query and closing connection when done. Then, I've just added methods to it for each thing I wanted to do (or could be subclassed too). Anyhow, when I need to do a certain action, I would just call that function and pass in whatever parameter(s) was(were) needed.
