Windows 10 .NET 3.5 安装

Question

我使用的是 Windows 10 的 build 9841。我下载了 .NET 3.5 SP 1 完整版。我双击安装程序但没有任何反应。.NET 版本与 Windows 10 不兼容吗？我需要它来安装 SQL Server 2014 Express。

Answer 1

.Net Framework 应该已经内置到 Windows 10 中，您可以从控制面板启用它。

执行以下操作以在 Windows 10 上启用 .Net Framework

1. 按键盘上的Windows+R键。
2. 在“运行”命令框中键入“ appwiz.cp l”，然后按“ ENTER ”。
3. 在“程序和功能”窗口中，单击“打开或关闭 Windows 功能”链接。
4. 检查“ .NET Framework 3.5（包括.NET 2.0 和3.0） ”选项是否可用。
5. 如果是，则启用它，然后单击“确定”。
6. 如果出现提示，请按照屏幕上的说明完成安装并重新启动计算机

这篇文章解释了如何（未测试）

Insert your Windows 10 DVD, or double click its ISO image, or insert your bootable flash drive with Windows 10, depending on what you have.
Open 'This PC' in File Explorer and note the drive letter of the installation media you have inserted. In my case it is disk D:
installation media drive d
Now open an elevated command prompt and type the following command:

Dism /online /enable-feature /featurename:NetFX3 /All /Source:D:\sources\sxs /LimitAccess

Replace D: with your drive letter for Windows 10 installation media.
dism

To save your time, I have prepared a simple batch file which will save your time and will find the inserted installation media automatically. It looks like this:

@echo off
Title .NET Framework 3.5 Offline Installer
for %%I in (D E F G H I J K L M N O P Q R S T U V W X Y Z) do if exist "%%I:\\sources\install.wim" set setupdrv=%%I
if defined setupdrv (
echo Found drive %setupdrv%
echo Installing .NET Framework 3.5...
Dism /online /enable-feature /featurename:NetFX3 /All /Source:%setupdrv%:\sources\sxs /LimitAccess
echo.
echo .NET Framework 3.5 should be installed
echo.
) else (
echo No installation media found!
echo Insert DVD or USB flash drive and run this file once again. 
echo.
)
pause
