insert mac addresses into a table of sqlite db

You could probably write a sql query to generate all the address in a temp table and insert them at the end. Can even do it in batches

Hmnm, I'm not sure that will work for me. Mine is database-first. I'm not sure how to implement this change

EF Core Loses Decimal Precision After Save

I have a Mapper class where I can override it if I have to, so it wouuldn't be too big of a deal to do it manually. Just wanted to check in case there was something already out there that does it

✅ IMemoryCache missing Contains?

I see what you mean. I was confused because when I google it, everything says "just use contains", but I can't find contains. Nonetheless, I think I can see how I can just use TryGetValue or GetOrCreate to do what needs to be done. I suppose that check isn't necessary

Okay, cool. Funny, I'm using MemoryCach to store ConcurrentDictionaries 😄

✅ IMemoryCache missing Contains?

True, I suppose I could do that. Doesn't seem very efficient, but that would work

✅ MediatR Pipeline where TResponse has a generic type

I want to use MediatR's pipeline to log exceptions to a separate database. But I'm not quite sure how to add a third generic type to the IPipelineBehavior. I tried this:

// Without response object
public class ExceptionPipeline<TRequest, TResponse> : IPipelineBehavior<TRequest, Result> 
{
    private IExceptionHandler _handler;

    public ExceptionPipeline(IExceptionHandler handler) 
    {
        _handler = handler;
    }

    public async Task<Result> Handle(TRequest request, RequestHandlerDelegate<Result> next, CancellationToken cancellationToken) 
    {
        Result response;
        try 
        {
            response = await next();
        } catch (Exception ex) 
        {
            var message = await _handler.LogException(ex);
            response = Result.Failure(message);
        }
        return response;
    }
}

// With response object
public class ExceptionPipeline<TRequest, TResponse, TResult> : IPipelineBehavior<TRequest, Result<TResult>> 
{
    private IExceptionHandler _handler;

    public ExceptionPipeline(IExceptionHandler handler) 
    {
        _handler = handler;
    }

    public async Task<Result<TResult>> Handle(TRequest request, RequestHandlerDelegate<Result<TResult>> next, CancellationToken cancellationToken) 
    {
        Result<TResult> response;
        try 
        {
            response = await next();
        } catch (Exception ex) 
        {
            var message = await _handler.LogException(ex);
            response = Result<TResult>.Failure(message);
        }
        return response;
    }
}

// Without response object
public class ExceptionPipeline<TRequest, TResponse> : IPipelineBehavior<TRequest, Result> 
{
    private IExceptionHandler _handler;

    public ExceptionPipeline(IExceptionHandler handler) 
    {
        _handler = handler;
    }

    public async Task<Result> Handle(TRequest request, RequestHandlerDelegate<Result> next, CancellationToken cancellationToken) 
    {
        Result response;
        try 
        {
            response = await next();
        } catch (Exception ex) 
        {
            var message = await _handler.LogException(ex);
            response = Result.Failure(message);
        }
        return response;
    }
}

// With response object
public class ExceptionPipeline<TRequest, TResponse, TResult> : IPipelineBehavior<TRequest, Result<TResult>> 
{
    private IExceptionHandler _handler;

    public ExceptionPipeline(IExceptionHandler handler) 
    {
        _handler = handler;
    }

    public async Task<Result<TResult>> Handle(TRequest request, RequestHandlerDelegate<Result<TResult>> next, CancellationToken cancellationToken) 
    {
        Result<TResult> response;
        try 
        {
            response = await next();
        } catch (Exception ex) 
        {
            var message = await _handler.LogException(ex);
            response = Result<TResult>.Failure(message);
        }
        return response;
    }
}

But I get an error that basically says the implementation Type can't be converted to the service type. Any help would be appreciated!

Excellent. It’s all becoming clear to me now. Thank you 😊

MediatR in Class Library

You mean, by using MediatR’s request/response and notification systems, MediatR will handle any surplus injections?
