如何使EF核心迁移不再冗长
问题描述:
我正在使用Entity Framework Core 1.1.0进行迁移。当我运行它们时如何使EF核心迁移不再冗长
dotnet ef database update
在包管理器控制台中,控制台充满了应用的SQL。与此相反,我想仅打印当前正在应用的迁移名称。我怎样才能做到这一点?

我假定你的项目的配置。
要禁用SQL打印试试这个
var builder = new DbContextOptionsBuilder<NAMEContext>();
builder.UseMySql(connectionString);
builder.UseLoggerFactory(new MigrationLoggerFactory()); <--- this seems to be what you are looking for
return new MigrationDataContext(builder.Options);
MigrationLoggerFactory
public class MigrationLoggerFactory : ILoggerFactory
{
public void Dispose() { }
public ILogger CreateLogger(string categoryName)
{
if ("Microsoft.EntityFrameworkCore.Migrations".Equals(categoryName))
return new MigrationLogger();
return new NullLogger();
}
public void AddProvider(ILoggerProvider provider)
{
}
}
NullLogger
public class NullLogger : ILogger
{
public void Log<TState>(LogLevel logLevel, EventId eventId, TState state, Exception exception, Func<TState, Exception, string> formatter)
{
throw new NotImplementedException();
}
public bool IsEnabled(LogLevel logLevel)
{
return false;
}
public IDisposable BeginScope<TState>(TState state)
{
return null;
}
}
