Container exited with a non-zero exit …我可以在用户打开Visual Studio IDE后立即为后台运行的Visual Studio创建扩展吗？例如,我正在构建一个扩展,在Visual Studio中获取当前活动文件地址(使用C#),但我希望此扩展始终在后台运行,而无需用户单击按钮或按某个键激活组合.
这是可能的,如果是这样,最好的方法是什么？
任何帮助将不胜感激!此致,Erfan
我想创建一个Eclipse插件,只要用户打开Eclipse IDE,它就会在后台自动运行.
例如,我正在构建一个获取当前活动文件地址的Java Eclipse插件,但我希望此插件始终在后台运行,而无需用户手动运行它.
怎么做到这一点？
