How do I query the. Net Framework version information in Windows Server?

Today, in the previously built system environment, query the version number information of the. Net framework, and collate the method and version number comparison table for your reference.

Query Method one:

Open IE Browser, enter "Javascript:alert (navigator.useragent)" In the Address bar, and a pop-up box will show which. NET versions are installed locally.

Note: Enter the character capitalization to match the above.

Query Method two:

Open My Computer, enter "%SystemRoot%\Microsoft.NET\Framework" in the Address bar, and under the path shown there will be a folder created by the. NET Framework version, the highest version being the current environment. NET version.

This is the version method for querying the. NET Framework, along with the version Information comparison table for the. NET Framework for query use:
