im trying to migrate RC1 project to RC2. My project restoring and building succesfuly. But when i type dotnet run i got Exception: Could not find method: 'Microsoft.Extensions.Configuration.IConfigurationBuilder Microsoft.Extensions.Configuration.IConfigurationBuilder.Add(Microsoft.Extensions.Configuration.IConfigurationProvider)'.
And this is my Startup constructor:
public Startup(IHostingEnvironment env)
{
Log.Logger = new LoggerConfiguration().MinimumLevel.Debug().
WriteTo.RollingFile(@"C:\log\file-{Date}.txt",
outputTemplate:
"{Timestamp: yyyy-MM-dd HH:mm:ss.fff zzz} {Level}:{EventId} [{SourceContext}] {Message}{NewLine}{Exception}")
.CreateLogger();
var builder = new ConfigurationBuilder() //<-error in this line
.SetBasePath(env.ContentRootPath)
.AddJsonFile("appsettings.json")
.AddJsonFile("config.json")
.AddEnvironmentVariables();
Configuration = builder.Build();
}
And this is my project.json:

You're using mismatched versions of packages. Specifically, the exception is caused by this line:
"Microsoft.Extensions.Configuration.EnvironmentVariables": "1.0.0-rc1-final",
Other packages are RC2, this one is RC1. This means that AddEnvironmentVariables() is the RC1 version, and it tries to call a method from its dependency, which was changed in RC2.
To fix this, use only RC2 packages.
