A Standard compliant client to wrap EF Core operations that can be used in a Storage Broker.
- InsertAsync
- SelectAllAsync
- SelectAsync
- UpdateAsync
- DeleteAsync
- BulkInsertAsync
- BulkReadAsync
- BulkUpdateAsync
- BulkDeleteAsync
Currently a storage broker looks something this:
public partial class StorageBroker : EFxceptionsContext, IStorageBroker
{
private readonly IConfiguration configuration;
public StorageBroker(IConfiguration configuration)
{
this.configuration = configuration;
this.Database.Migrate();
}
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
base.OnModelCreating(modelBuilder);
AddConfigurations(modelBuilder);
}
private static void AddConfigurations(ModelBuilder modelBuilder)
{
. . .
}
protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
{
. . .
}
private async ValueTask<T> InsertAsync<T>(T @object)
where T : class
{
this.Entry(@object).State = EntityState.Added;
await this.SaveChangesAsync();
this.Entry(@object).State = EntityState.Detached;
return @object;
}
private async ValueTask<IQueryable<T>> SelectAllAsync<T>()
where T : class =>
this.Set<T>();
private async ValueTask<T> SelectAsync<T>(params object[] @objectIds)
where T : class =>
await this.FindAsync<T>(objectIds);
private async ValueTask<T> UpdateAsync<T>(T @object)
where T : class
{
this.Entry(@object).State = EntityState.Modified;
await this.SaveChangesAsync();
this.Entry(@object).State = EntityState.Detached;
return @object;
}
private async ValueTask<T> DeleteAsync<T>(T @object)
where T : class
{
this.Entry(@object).State = EntityState.Deleted;
await this.SaveChangesAsync();
this.Entry(@object).State = EntityState.Detached;
return @object;
}
}With the client it will look like this and it addresses the sequencing issue that we currently have in brokers.
public partial class StorageBroker : EFxceptionsContext, IStorageBroker
{
private readonly IConfiguration configuration;
private readonly IEFCoreClient efCoreClient;
public StorageBroker(IConfiguration configuration)
{
this.configuration = configuration;
this.Database.Migrate();
this.efCoreClient = new EFCoreClient(this);
}
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
base.OnModelCreating(modelBuilder);
AddConfigurations(modelBuilder);
}
private static void AddConfigurations(ModelBuilder modelBuilder)
{

}

{

}

await efCoreClient.InsertAsync(@object);
