Asp.Net 样板启动模板 - 文化问题

我已经下载了 ASP.NET Boilerplate 的启动模板。

已成功按照说明创建和播种数据库。

当我进入运行应用程序时，出现以下错误：

据我所知，vn 文化标识符是越南语，但我无法确定此错误是如何产生的，以及我能做些什么来确保 en 文化是因为我在英国所以使用。

如有任何建议，我们将不胜感激。

打开 DefaultLanguagesCreator class 并使用以下更改构造方法；

static DefaultLanguagesCreator()
        {
            InitialLanguages = new List<ApplicationLanguage>
            {
                new ApplicationLanguage(null, "en", "English", "famfamfam-flags gb"),
                new ApplicationLanguage(null, "tr", "Türkçe", "famfamfam-flags tr"),
                new ApplicationLanguage(null, "zh-CN", "简体中文", "famfamfam-flags cn"),
                new ApplicationLanguage(null, "pt-BR", "Português-BR", "famfamfam-flags br"),
                new ApplicationLanguage(null, "es", "Español", "famfamfam-flags es"),
                new ApplicationLanguage(null, "fr", "Français", "famfamfam-flags fr"),
                new ApplicationLanguage(null, "it", "Italiano", "famfamfam-flags it"),
                new ApplicationLanguage(null, "ja", "日本語", "famfamfam-flags jp"),
                new ApplicationLanguage(null, "nl-NL", "Nederlands", "famfamfam-flags nl"),
                new ApplicationLanguage(null, "lt", "Lietuvos", "famfamfam-flags lt"),
                new ApplicationLanguage(null, "vi", "Vietnamese", "famfamfam-flags vi")
            };
        }

此外，您需要更新数据库，因为种子方法不会更新您现有的语言。打开 AbpLanguages table 并更新行越南语；名称=vi，图标=famfamfam-flags vi.

update AbpLanguages set Name='vi', Icon='famfamfam-flags' where Name='vn'
