Microsoft .Net Framework 4.7.2 is a new version of Microsoft's .Net Framework. The new version is integrated in the Windows 10 April 2018 Update release; if you run older versions of Windows, you may download and install the new version to update the framework to the latest version.
Microsoft released updates for Windows 7 and Windows 8.1 as well as Windows 7 versions 1607, 1703 and 1709.
Windows users and administrators may download a web installer or offline installer. The Web Installer is just a small-sized installer which downloads the .Net Framework 4.7.2 from Microsoft servers during installation; the offline installer is a bigger download but it does not require an Internet connection during installation.
Note: the downloads are for all supported versions of Windows including Windows 10, Windows 8.1 and Windows 7 SP1 on the client-side, and Windows Server 2016, Windows Server 2012 R2 SP1 and Windows Server 2008 R2 SP1 on the server-side.
You don't need to download and install the new version if you run Windows 10 version 1803 as it is included already.
The offline installer has a size of 68 Megabytes.
Microsoft lists new features of the .NET Framework 4.7.2. on this Microsoft Docs page. Here are the highlights:
Should you update right away? In my opinion, it is probably better to wait and see if the new version causes any issues before you upgrade unless you need it for work or development right away.
I suggest you use the offline installer to update as it is less error-prone and reduces the connections your device makes to Microsoft to install the new NET version.
