I am new to C # programming and don’t know how to install the “Target Framework” in visual studio 2013? When I right-click on a project -> Properties, I do not see the left column of the property page window without an application bookmark. I tried to build a solution, and I had several such errors:
Error 6: Could not find the name of the type or namespace "ObjectSet" (do you miss the using directive or assembly references?)
And so I found this answer link
But I really don't know how to change the target structure. Please help me. Thanks in advance.
[EDIT] Screenshot. I am using Visual Studio Professional 2013
