在Visual Studio 2010中安裝iText 7.1失敗

Question

我正在使用Visual Studio 2010 Premium（不能為我的項目使用更高版本）。

我從工具->擴展管理器-> Online Gallery安裝了Visual Studio的NuGet軟件包管理器。

我安裝了作為iText7依賴項的'Common.Logging'和'Common.Logging.Core'軟件包。

我嘗試在前兩個軟件包之后安裝iText7，但由於出現“ Portable.BouncyCastle”軟件包也是iText7的依賴項，因此出現錯誤。

我嘗試安裝“ Portable.BouncyCastle”軟件包，但出現錯誤：

安裝軟件包：'Portable.BouncyCastle 1.8.1.3'軟件包需要NuGet客戶端版本為'2.12'或更高版本，但當前的NuGet版本為'2.8.60318.667'。

我在Visual Studio中從工具->擴展管理器->更新中檢查了NuGet客戶端的更新。 ，但找不到任何更新。

任何想法？

請嘗試在Nuget Package Manager控制台中使用以下代碼；

Install-Package itext7 -Version 7.0.3
