我安装了nuget包CommonServiceLocator，但我仍然收到此错误。奇怪的是我的web.config文件中有一个程序集绑定重定向，但程序集没有出现在我的项目的引用列表中，我无法在任何地方找到它来添加它。我还是相对较新的ASP.NET，所以我似乎无法确定问题究竟是什么。我发现尝试的另一件事是在IIS管理器中为我的应用程序池设置“启用32位应用程序”为true，但这并没有解决我的问题。我已经坚持了一段时间，所以任何帮助都会受到赞赏。

Answer 1

经过数小时的研究和尝试不同的事情，从Nuget卸载并重新安装CommonServiceLocator似乎可以解决问题。我仍然对.NET应用程序与其依赖项的混乱程度感到惊讶。

Answer 2

确保您已安装版本1.3.0而不是其他版本。

Nuget链接：https://www.nuget.org/packages/CommonServiceLocator/1.3.0

Answer 3

打开VS - ＆gt;工具 - ＆gt; Nuget包管理器 - ＆gt;包管理器控制台

>PM Install-Package CommonServiceLocator

这应该有帮助！

Answer 4

我收到此错误是因为我在旧版本中使用了C＃7.0的新语法。一旦我恢复到旧的语法，这就解决了。

具体来说，我正在使用： -

// Newer syntax.
if (int.TryParse(args.Value, out var value))
{
  args.IsValid = value > 0;
}

// Older supported version which resolved the issue.
int value;
if (int.TryParse(args.Value, out value))
{
  args.IsValid = value > 0;
}

Answer 5

我在VS2017中打开了VS2015解决方案，发现缺少参考，不确定原因。

无法找到程序集“ CommonServiceLocator”
无法找到程序集“ Unity.RegistrationByConvention”
无法找到程序集“ Unity.ServiceLocation”
无法找到程序集“ Unity.Configuration”
无法找到程序集“ Unity.Interception.Configuration”
无法找到程序集“ Unity.Container”

首先构建您的项目，以获取缺少的引用列表（显示发行版编号）。然后打开该解决方案的NUGET软件包管理器，然后重新安装即可。注意：安装顺序有依赖关系链，如果安装失败，请找到先决条件。依赖性，然后先安装，然后重试。大约需要10分钟才能更正。

Answer 6

他们已经更新了软件包，如果您下载最新的commonservicelocator软件包，则需要在代码中进行以下更改。

using Microsoft.Practices.ServiceLocation;

到

using CommonServiceLocator;

无法加载文件或程序集Microsoft.Practices.ServiceLocation，Version = 1.3.0.0
