如何正确设置edgedriver？得到以下错误

Question

我在C#中使用NUnit和Selenium来构建一个框架，其中包含在多个浏览器上运行多个测试用例。在这种情况下也支持Microsoft Edge。当我设置测试时，chrome和firefox正常运行，但edge出现以下错误：

OpenQA。硒。WebDriverException:向远程WebDriver服务器发送HTTP请求以获取URL时，引发了一个响应为null的异常http://localhost:55992/session.异常状态为ReceiveFailure，消息为：基础连接已关闭：receive上发生意外错误----

我试图查找这个特定的错误，我得到的最接近的结果是远程驱动程序试图发送一个HTTP请求，但在本例中失败了。由于Chrome和FF运行正常，我不知道Edge出了什么问题。

WebDriverFactory：

        Driver = WebDriver(type);

我也面临同样的问题，但后来我发现：

硒。Web驱动程序。microsoftDriver v17.17134.0在运行测试时崩溃

长话短说，检查你的Windows版本。如果是17134版本，则获取MicrosoftWebDriver 17134版本。但是，如果您在16299.xxx，那么您必须使用16299版本的MicrosoftWebDriver。
