Need proper syntax using EF6 Fluent API between 2 tables using PK and FK - entity-framework

Question

If you all need more details I will send them for sure. Here is a screen shot containing 2 tables:
Basically this is what looks like in SQL today:
I am trying to use the fluent API for the relationship but not sure how to do it.
Table 1 has a PK and a FK.
Table 2 does not have a PK, only FK.
Below is an example of what I need but this code applies to a different set of tables. I am trying to get the "relationship" syntax correct for the scenario described here:
this.ToTable("Server");
//primary key
this.HasKey(t => t.serverId);
//properties
...
//relationships
this.HasMany(n => n.NetworkAdapters)
.WithRequired(s => s.Server)
.HasForeignKey(s => s.serverId)
.WillCascadeOnDelete(true);
Thank you

Answer 1

Without the primary key on table 2 you are most likely looking for a One-to–Zero-or-One relationship. You might possibly be requiring both ends which I will describe too.
One-to–Zero-or-One
// Configure the primary key for Table1
modelBuilder.Entity<Table1>()
.HasKey(t => t.networkAdapterId);
// Map one-to-zero or one relationship
modelBuilder.Entity<Table2>()
.HasRequired(t => t.Table1)
.WithOptional(t => t.Table2);
One-to-One
// Configure the primary key for the Table1
modelBuilder.Entity<Table1>()
.HasKey(t => t.networkAdapterId);
// Map one-to-one relationship
modelBuilder.Entity<Table2>()
.HasRequired(t => t.Table1)
.WithRequiredPrincipal(t => t.Table2);
