Identifying Your Windows Version with .NET
Problem: How do we reliably determine the specific version of the Windows operating system within a .NET application?
Solution:
The System.Environment.OSVersion property offers a straightforward approach to identifying the Windows OS version. While effective for distinguishing major releases, it may not provide granular detail for all versions.
The OSVersion property comprises three key components:
| PlatformID | Major Version | Minor Version | Corresponding Windows Versions |
|---|---|---|---|
| Win32Windows | 4 | 0 | Windows 95 |
| Win32Windows | 4 | 10 | Windows 98 |
| Win32Windows | 4 | 90 | Windows Me |
| Win32NT | 4 | 0 | Windows NT 4.0 |
| Win32NT | 5 | 0 | Windows 2000 |
| Win32NT | 5 | 1 | Windows XP |
| Win32NT | 5 | 2 | Windows Server 2003 |
| Win32NT | 6 | 0 | Windows Vista, Windows Server 2008 |
| Win32NT | 6 | 1 | Windows 7, Windows Server 2008 R2 |
| Win32NT | 6 | 2 | Windows 8 |
| Win32NT | 6 | 3 | Windows 8.1 |
| Win32NT | 10 | 0 | Windows 10 |
Important Considerations:
- Enhanced Precision: For precise identification of Windows releases beyond the major versions listed above, consider employing a dedicated third-party library.
-
Manifest Impact: The accuracy of
System.Environment.OSVersioncan be influenced by your application's manifest file. Explicitly defining compatibility with Windows 8.1 and Windows 10 in your manifest ensures reliable results. -
.NET 5.0 and Beyond: In .NET 5.0 and subsequent versions,
System.Environment.OSVersiondelivers consistently accurate OS version information.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
