i am a c# web developer and vb.net project is not familiar for me.
i have a project in .net 2.0 that i want to upgrade it to .net 4.0 with using visual studio 2010.
when i open that project with visual studio 2010 every thing is normal and it seems it is working in .net 2.0.
i created a new project with visual studio and added all .net 2.0 project files to the new project.
but after that i had many errors like below :

'List' is not declared. It may be inaccessible due to its protection

what did i do wrong and how can i upgrade that project?
also where can i find the project’s .Net framework ver for VB language (in c# we can change it by right clicking on project and properties, but here there is no such a properties)?

thanks in advance
