EntityStoreSchemaGenerator很慢

Question

我一直试图将空的SQL 2012数据库反向工程为代码。我从实体框架电动工具中获取代码以进行逆向工程。我注意到，当我运行电动工具或运行下面的代码时，生成商店模式需要2个多小时。

数据库是否有问题，或者它本身就很慢？

EntityStoreSchemaGenerator entityStoreSchemaGenerator = new EntityStoreSchemaGenerator(provider, "Data Source=.;Initial Catalog=InSysV5;Integrated Security=True", "dbo")
            {
                GenerateForeignKeyProperties = true
            };

            entityStoreSchemaGenerator.GenerateForeignKeyProperties = true;
            var filter1 = new EntityStoreSchemaFilterEntry(null, null, null, EntityStoreSchemaFilterObjectTypes.Table, EntityStoreSchemaFilterEffect.Allow);
            var filter2 = new EntityStoreSchemaFilterEntry(null, null, null, EntityStoreSchemaFilterObjectTypes.View, EntityStoreSchemaFilterEffect.Exclude);
            var filter3 = new EntityStoreSchemaFilterEntry(null, null, null, EntityStoreSchemaFilterObjectTypes.Function, EntityStoreSchemaFilterEffect.Exclude);
            var filters = new EntityStoreSchemaFilterEntry[] { filter1, filter2, filter3 };
            var errors1 = entityStoreSchemaGenerator.GenerateStoreMetadata(filters);
