Overriding code-generated DbContext constructor

Question

I\'m sure I\'ve done this before at some stage, but I can\'t figure out how to now! My scenario:

// This is generated from EDMX
public partial class HOLDbEnt         


        

Answer 1

i changed the context.tt as follows:

<#=Accessibility.ForType(container)#> partial class <#=code.Escape(container)#> : DbContext
{
    public <#=code.Escape(container)#>()
        : base("name=<#=container.Name#>")
    {

<#
if (!loader.IsLazyLoadingEnabled(container))
{
#>
        this.Configuration.LazyLoadingEnabled = false;
<#
}
foreach (var entitySet in container.BaseEntitySets.OfType())
{
    // Note: the DbSet members are defined below such that the getter and
    // setter always have the same accessibility as the DbSet definition
    if (Accessibility.ForReadOnlyProperty(entitySet) != "public")
    {
#>
        <#=codeStringGenerator.DbSetInitializer(entitySet)#>
<#
    }
}
#>
var Method = (typeof(Entities)).GetMethods(System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance).FirstOrDefault(x => x.Name == "OnModelConstructed");
if (Method!=null) Method.Invoke(this,null);
    }

so i can declare a OnModelConstructed method in a partial class of the context.
