PersistKeysToDbContext
dotnet add package Microsoft.AspNetCore.DataProtection.EntityFrameworkCore
Add using Microsoft.AspNetCore.DataProtection; to Startup.cs
builder.Services.AddDataProtection()
.PersistKeysToDbContext<SampleDbContext>();
The preceding code stores the keys in the configured database. The database context being used must implement IDataProtectionKeyContext. IDataProtectionKeyContext exposes the property DataProtectionKeys
public DbSet<DataProtectionKey> DataProtectionKeys { get; set; } = null!;
