C# 无法加载'；贝宝&x27；从您的配置中删除部分

我遇到了PayPal SDK for.NET的问题。我已在Web.config中填写了我的设置，但当我尝试使用PayPal SDK的ConfigManager获取这些设置时，出现以下错误：

Unable to load 'paypal' section from *.config: An error occurred creating the configuration section handler for paypal: Exception has been thrown by the target of an invocation.

我希望有人以前可能遇到过这个问题，或者知道如何帮助我

我还尝试使用ConfigurationManager.GetSection（“paypal”）手动加载Web.config设置，但也没有成功

提前谢谢，希望你能帮助我

按照Jason Z的建议卸载.NET Framework 4.6 RC，修复了我的问题

我确信在较新版本的PayPal SDK中，它可以与.NET4.6兼容，但不幸的是，目前它还不能

---

在安装PayPal SDK 1.4.2而不是1.4.3时，它似乎也能工作。

您是否碰巧安装了.NET 4.6 RC？我们正在跟踪此问题。看起来我有.NET 4.6，是的。我将重新安装它，然后改用.NET 4.5.1重试，谢谢！谢谢你的帮助，它解决了我的问题！
