NET.Framework 2.0是干什么用的

Microsoft.NET Framework 2.0版是Microsoft.NET Framework的最新更新，其中包括了您運行使用.NET Framework開發(fā)的應(yīng)用程序時所需的所有內(nèi)容。

Microsoft.NET Framework 2.0版提供了改進的緩存、使用 ClickOnce改進了應(yīng)用程序部署和更新、通過 ASP.NET 2.0控件和服務(wù)對最廣泛的瀏覽器和設(shè)備提供更強大的支持，從而提高了可擴展性和性能。

重要事項：不能在同一臺計算機上安裝兩種不同語言版本的.NET Framework。試圖安裝第二種語言版本的.NET Framework時，將會導(dǎo)致出現(xiàn)以下錯誤：“安裝程序無法安裝 Microsoft.NET Framework，因為已經(jīng)安裝了該產(chǎn)品的其他版本?！比绻褂梅怯⒄Z的平臺或要以另一種語言查看.NET Framework資源，則必須下載相應(yīng)語言版本的.NET Framework語言包。

Microsoft�0�3.NET Compact Framework 2.0 SP2 Redistributable更新:

The Microsoft�0�3.NET Compact Framework 2.0 SP2 Redistributable包含為.NET Compact Framework構(gòu)建的公共語言運行庫和類庫。除支持版本 2.0外，它還支持面向版本 1.0及其在版本 2.0之前已發(fā)布的 Service Pack版本開發(fā)的應(yīng)用程序。

重要說明：此可再發(fā)行組件包使用戶可以在 Pocket PC、Pocket PC Phone Edition、Smartphone和其他基于 Windows CE的設(shè)備上運行.NET Compact Framework應(yīng)用程序。要開發(fā).NET Compact Framework應(yīng)用程序，必須安裝 Microsoft Visual Studio 2005或 Microsoft.NET Framework 2.0 SDK。

Microsoft.net Framework 2.0安裝失敗怎么辦

解決辦法：

1、請點擊下載.NET Framework自動清理工具。在文件下載窗口，單擊“保存”按鈕將文件另外保存（這里我們保存至桌面）。

2、這是一個壓縮文件。請將其解壓縮（這里，小易仍然以將其解壓到桌面為例）。

3、雙擊運行 Cleanup_tool.exe清理工具，彈出確認窗口后，請單擊“是”繼續(xù)。

4、接下來出現(xiàn)的窗口會是英文界面的。不要擔心，跟著小易操作就好啦。彈出協(xié)議告示窗口后，按一下“Yes”按鈕確認并繼續(xù)。

5、“Product to cleanup”（清理產(chǎn)品）一項，請在右邊下拉菜單中選擇“.NET Framework- All Versions(...)“（所有版本的.NET Framework），然后單擊“Cleanup Now”(立即清理)繼續(xù)。

6、出現(xiàn)“Product cleanup succeeded!”信息后，就表示清理已經(jīng)完成了。按一下“Exit”(退出)關(guān)閉窗口。請重啟計算機以重新安裝您所需要的.NET Framework。

microsoft .net framework 2.0安裝不了

經(jīng)查證，win xp pro和home版本有可能會出現(xiàn)此問題，除會發(fā)生以上現(xiàn)象外，當您嘗試在“控制面板”中打開“管理工具”時，可能不會執(zhí)行任何操作。

問題的原因在于注冊表設(shè)置不正確

解決方法：

1.開始-運行-鍵入 regedit-回車。

2.找到以下注冊表項：

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders

3.在“注冊表編輯器”的右窗格中，雙擊常見管理工具。

4.在“數(shù)值數(shù)據(jù)”框中，鍵入以下行，然后單擊確定：

%ALLUSERSPROFILE%\Start Menu\Programs\Administrative Tools

5.在文件菜單上，單擊退出以退出注冊表編輯器。

6.重啟電腦。

如果以上辦法無效活著在你的系統(tǒng)上找不到對應(yīng)注冊表鍵值時，把以下所有內(nèi)容復(fù)制到文本文檔，保存為注冊表文件*.reg，雙擊導(dǎo)入。
