Importing 2008 Visual Studio Project (3.5 .NET) into Visual Studio 2013

Question

I'm trying to continue a project (outlook addin, Visual Basic) which was done with Visual Studios 2008. When i import this in Visual Studios 2013 it instantly starts converting it into a newer Framework which results in a lot of errors and necessary manual changes.

I tried to change the target Framework in the Project Options afterwards but im just getting an error.

Im just wondering if there is any way to import this project instantly as a 3.5.NET project?

Greetings

I got it!

Had to delete the <Assembly: SecurityTransparent()> Attribute. Apparently Visual Studios doesnt delete it.
