I have decided to use .NET 3.5.1 but when I add the DocumentFormat.OpenXml 2.5 throught the NuGet Package Console with Install-Package DocumentFormat.OpenXml I get a lot of warnings :
1>C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets(1605,5): warning MSB3258: The primary reference "DocumentFormat.OpenXml, Version=2.5.5631.0, Culture=neutral, PublicKeyToken=123, processorArchitecture=MSIL" could not be resolved because it has an indirect dependency on the .NET Framework assembly "System.Data.SqlXml, Version=4.0.0.0, Culture=neutral, PublicKeyToken=123" which has a higher version "4.0.0.0" than the version "2.0.0.0" in the current target framework.

It seems like DocumentFormat.OpenXml 2.5 needs or is using .Net 4.
Should I worry about these warnings [and stick to .net 4.5 where I don't get these warnings]?
I want to avoid .net 4.5 since they need admin rights to be installed.
