IRelyingPartyStore

To store RelyingParty entities, an implementation of IRelyingPartyStore must be registered.

In-Memory

A default, in-memory implementation be registered like so:

services.AddIdentityServer()
    // existing registrations
    .AddInMemoryRelyingParties(new List<RelyingParty>());

Entity Framework

An entity framework implementation can be found in the Rsk.WsFederation.EntityFramework nuget package. This store can be registered using the following:

services.AddDbContext<WsFederationConfigurationDbContext>(options => { /* DbContext setting */})
services.AddScoped<IWsFederationConfigurationDbContext, WsFederationConfigurationDbContext>();

services.AddIdentityServer()
    // existing registrations
    .AddRelyingPartyStore<RelyingPartyStore>();

Creating a Custom Implementation

A custom store for relying parties can be created by implementing IRelyingPartyStore and then registering that implementation with AddRelyingPartyStore<>().

public interface IRelyingPartyStore
{
    Task<RelyingParty> FindRelyingPartyByRealm(string realm);
}
