I'm struggling to figure out how to set up my Visual Studio 2010 c# based solution. &nbsp;I want to create a library to used by both a web application and windows application. &nbsp;The solution will store data in a SQL Server db via Entity Framework 4.0.<br />

It seems common practice to put the model in a seperate library but how much application logic to add to this? &nbsp;For example I am downloading data from Paypal so am saving Paypal transactions in the DB. &nbsp;So in my core library do I have a PaypalSystem (what I communicate with to retrieve the transactions) and put PaypalTransaction in the Model library? &nbsp;It seems a muddle to me and I think I could use advice or an example!

Why place EF model in seperate project

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.

.NET Programming

Microsoft Visual C++ (often abbreviated as MSVC or VC++) is an integrated development environment (IDE) product from Microsoft for the C, C++, and C++/CLI programming languages. It features tools for developing and debugging C++ code, especially code written for the Microsoft Windows API, the DirectX API, and the Microsoft .NET Framework. Many applications require redistributable Visual C++ packages to function correctly and are often installed independently of applications, allowing multiple applications to make use of the package while only having to install it once

Visual C++.NET

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).
