I'm a bit confused by the NET Framework-versioning. When I'm "targetting v.3.5", what really happens is that C# 3.0 compiler will be used in combination with assemblies from %WINDOWS%\Microsoft.NET\Framework\v3.5. The .NET runtime which actually executes the code later on will be the same (2.0). Correct?
So let's say I have an API, targetting 3.5 with as single class with 3 functions:
void Test1(int) {return null;}
void Test2(System.Data.DataSet) {return null;}
void Test3(DataContext) {return null;}
As I understand it, a client targetting v2.0 (using VS2005)
- will be able to instantiate this class and call Test1(). The VS2005 C# compiler recognizes void and int and will compile.
- may be able to call Test2() if the version of System.Data in framework 2.0 is the same as in framework 3.5. If not, the compiler will complain that it cannot find the type System.Data.DataSet of the specific version used in the API.
- will not be able to call Test3(), since "DataContext" isn't defined in any of the referenced assemblies (since it's in the 3.5 framework)
Am I right here or am I on the wrong track?
