Our team builds a .NET 3.5 WinForms based application that we'd like to migrate to the latest .NET version (4.5).

Our application uses many "external" components (can be thought of as plugins) that are also currently .NET 3.5 based.

I'd like to know what runtime/core libraries are used in case we convert ONLY THE APPLICATION to compile using .NET 4.5?

Should this scenario properly work? (loading .NET 3.5 assemblies in a 4.5 process)? * The plugin assemblies are loaded via reflection.

How does the CLR runtime handle such a scenario? is this a safe practice?

COM Interop with Visual FoxPro has a number of problems but one of them at least got a lot… >>> More
Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
Finding a Relative Path in .NET
