I could not find answer that would resolve my issue. I'm getting 2 exceptions in my minimal API:
1: System.AggregateException
Some services are not able to be constructed (Error while validating the service descriptor 'ServiceType: MinApiEFCore.Data.ConnectRepo Lifetime: Singleton ImplementationType: MinApiEFCore.Data.ConnectRepo': Unable to resolve service for type 'DocuWare.Platform.ServerClient.ServiceConnection' while attempting to activate 'MinApiEFCore.Data.ConnectRepo'.) (Error while validating the service descriptor 'ServiceType: MinApiEFCore.Data.IConnectRepo Lifetime: Scoped ImplementationType: MinApiEFCore.Data.ConnectRepo': Unable to resolve service for type 'DocuWare.Platform.ServerClient.ServiceConnection' while attempting to activate 'MinApiEFCore.Data.ConnectRepo'.)'
2: InvalidOperationException
Unable to resolve service for type 'DocuWare.Platform.ServerClient.ServiceConnection' while attempting to activate 'MinApiEFCore.Data.ConnectRepo'.
"ServiceConnection" is from an "external" class from DocuWare (via NuGet) used for creating a connection.
My IConnectRepo interface looks like this:
public interface IConnectRepo
{
ServiceConnection CreateServiceConnectionAsync(Uri uri, string user, string password);
}
ConnectRepo class:
public class ConnectRepo : IConnectRepo
{
private ServiceConnection _serviceConnection;
public ConnectRepo(ServiceConnection serviceConnection)
{
_serviceConnection = serviceConnection;
}
public ServiceConnection CreateServiceConnectionAsync(Uri uri, string user, string password)
{
//Organizations == null means I am not connected
if (_serviceConnection.Organizations.FirstOrDefault() == null)
{
_serviceConnection = ServiceConnection.Create(uri, user, password);
}
return _serviceConnection;
}
}
Program.cs
..
builder.Services.AddScoped<IConnectRepo, ConnectRepo>();
..
Still not sure why I cannot inject ServiceConnection in the constructor. Any help would be appreciated.
You cannot inject ServiceConnection as it has not been added to DI container. You can register the service like following...
..
builder.Services.AddScoped<IConnectRepo, ConnectRepo>();
builder.Services.AddScoped<ServiceConnection>();
..
...but then you will run into another problem as ServiceConnection doesn't have public parameterless constructor.
Resolution for this is to instruct DI container how to create ServiceConnection instance.
..
builder.Services.AddScoped<IConnectRepo, ConnectRepo>();
builder.Services.AddScoped<ServiceConnection>(sp => ServiceConnection.Create("some service URI"));
..
Be aware that you might need to use different service lifetime to avoid performance issues.
