Trying to build from source but getting: MSB3644 The reference assemblies for .NETFramework,Version=v4.5 were not found

Very sorry if this is too simple of a question, I am new to C#. I'm trying to build the sample app from source. But I keep getting solution errors when I build:

And a lot of warnings:

Do I need to install the .NET 4.5 targeting pack to get this working? How can I successfully build this?

Edit:

More warnings:

As per the error, you haven't installed .NET 4.5
To solve this issue either you need to down it or change the Target framework.

To install .NET 4.5 framework from Visual Studio Installer follow the following steps:

• Open Visual Studio Installer.
• Click on modify.
  
• Click on Individual components
  
• Select .NET Framework 4.5.2 targeting pack
  
• Click on modify on bottom right hand.

Or you can change the Target framework from your project

1. Right click on your project.
2. Click on properties.
3. In application tab selected the new target framework you have installed in your computer.
