Integration with CRM SDK 2016

I have a C# WPF application that integrated with CRM sdk 2011 using organization data end point to retrieve and update data on the CRM 2011 using .net 4.5

now i have installed CRM 2016 and i want to integrate this application with CRM SDK 2016. so i installed from the nuget the CRM SDK 2016 using the following :Install-Package Microsoft.CrmSdk.Deployment 8.1.0.2.

after that  when i build the application using .net 4.5  i'm getting the following error :binary format of the specified custom attribute was invalid

so i want  to make sure if i have to change the .net framework to 4.5.2 or what are the steps to integrated with CRM SDK 2016

Thank you for your help
