C # What happens if I use the code for the .NET 3.5 function on a machine with .Net 2 installed

Question

Just out of interest, if I built some code using the Enumerable.Distinct function that appeared in .Net 3.5 and then ran it on a machine with .Net 2.0, what would happen?

Answer 1

The program will crash as soon as the assembly that defines Enumerable.Distinct(System.Core) is required . However, you can make it work if you target .NET 2.0 and use LinqBridge instead of System.Core.

Answer 2

3.5 Framework 2.0 Framework, 3.5 Framework. Enumerable.Distinct, 3.5 Framework, .

Answer 3

.Net 2.0 , .

Answer 4

.NET 3.5 - , ,.NET 2.0 + .

, ...NET 3.5 , .

- , , , , , . , , .NET 3.5, .

, , .NET 3.5 (SP1).

Answer 5

Most likely, your code will complain that .net 3.5 is not installed at startup.

Answer 6

Simple, it will crash at the entrants where you used the specific functions of .net 3.5.

But the main question ... why do you want to do this?

If you migrated a project from .net freamework version 2.0 to 3.5 and don’t use any .net 3.5 function, you cannot imagine a valid frame migration
