一个 asp.net core 程序，之前在 .net core 3.0 preview 4 上可以正常运行，昨天升级到 preview 5 后运行时出现下面的错误：

Microsoft.AspNetCore.Server.Kestrel
System.TypeLoadException: Could not load type 'Microsoft.EntityFrameworkCore.Metadata.RelationalAnnotationsBuilder' from assembly 'Microsoft.EntityFrameworkCore.Relational, Version=3.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'.
   at Microsoft.EntityFrameworkCore.SqlServer.Metadata.Internal.SqlServerModelBuilderAnnotations..ctor(InternalModelBuilder internalBuilder, ConfigurationSource configurationSource)

请问如何解决？
