I once used Win10&VS2017 in chinese, so I got display language in CMD was chinese, it looked like:

Microsoft (R) 测试执行命令行工具版本 15.0.0.0 版权所有 (C) Microsoft
Corporation。保留所有权利。

正在启动测试执行，请稍候...
ConsoleApp.Sqlite.Test.PrimeServiceIsPrimeShould.ReturnFalseGivenValueOf1
个失败 错误消息: Unable to get default constructor for class
ConsoleApp.Sqlite.Test.PrimeServiceIsPrimeShould.

总测试: 1。已通过: 0。失败: 1。已跳过: 0。 测试运行失败。 测试执行时间: 0.5729 秒

Then I changed my Win10's & VS2017's language to english, everything was fine (display in english) except the VSTest tools, it still displayed in chinese.

So my question is, how chould I change the language of VSTest tools to english?

Cache related? or language package of .Net Framework?
