.Net framework 4.5.2 for Visual Studio 2010

.Net framework 4.5.2 for Visual Studio 2010 If you have installed Visual Studio 2010 on Windows 7, 8, 10 recently, you will notice that you have all .Net Framework versions available, and you will notice also that you Windows updates .net framework versions to a higher versions (i.e. If you have .net framework 4, windows will update this to 4.5) but you won't find .net framework v4.5 in your Visual Studio 2010, why ?!
Because targeting .net framework 4.5 via Visual Studio 2010 Each version of VS prior to Visual Studio 2010 is tied to a certain .NET framework. (VS2008 is .NET 3.5, VS2005 is .NET 2.0, VS2003 is .NET1.1) VS2010 and beyond allow for targeting of prior framework versions but cannot be used for future releases. You must use Visual Studio 2012 in order to utilize .NET 4.5.
