c# - Changing the project's targeted framework -

I have created a vanophya project that targets the framework. Net Framework 4.5

I want this project to be consistent with the lower framework, as such. Net2 or .Net 3

Is this possible? If yes, then, what is the result? Please tell me I do not have to make any amendments to the source code.

Yes, you can downgrade your project using the project settings in Visual Studio.

However: All sources must follow .NET 2 or .NET 3, which platform you have to target. This means that if you use TLL for lambda quote, LINQ, async / await, for example, you can not use them more, and you have to edit them to compile your source code.

Just for the record, I do not care too much for NAT 2 and 3 because if you really want them in a business environment then I will try.
