每当您使用在您的项目中引用的预发布包时出现类型或缺少方法异常 NuGet.config:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<packageSources>
<add key="ServiceStack MyGet feed" value="https://www.myget.org/F/servicestack" />
<add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
</packageSources>
</configuration>
通常是因为在不同的时间下载相同的预发布包版本，您可以通过删除 NuGet 包缓存来解决这个问题：
$ nuget locals all -clear
然后再次恢复您的包，这会获取每个包的最新版本，确保它们都是同时构建的。
作为额外的预防措施，我已经重新构建并部署了所有预发布包，因此只需重新运行 任务也可能会解决它。
