如何在visual studio 2013中设置“目标框架”？

Question

I am new to C# programming and don't know how to set the "Target Framework" in visual studio 2013? When I right click on the project -> Properties I see no left column of the property pages window with no Application tab. I tried to build a solution and I got several errors like this:

Error 6 The type or namespace name 'ObjectSet' could not be found (are you missing a using directive or an assembly reference?)

And then I found this answer link

But I don't actually know how to change the target framework. Please help me. Thank you in advance.

[EDIT] Screenshot. I use Visual Studio Professional 2013

Answer 1

Right Click a project > click properties > first tab -> Target Framework

Looking at the error it seems like you are missing reference to dlls. Please look at this Link
