Is it possible to open / edit a normal Visual Studio Solution with Visual Studio Express Edition ?
Yes this is possible with restrictions (not all project types are supported). You must edit the second line of sln-File. For example change "# Visual Studio 2010" to "# Visual C# Express 2010" This works for example for class libs or Windows Forms applications.
It depends. If this normal solution includes a unit testing project for example or a load tests or a modeling project (architecture, UML), then the answer is no. Class libraries, console applications, WinForm, ASP.NET, ... should be ok.
