Unable to use S3 Path Style Access S3 URL

[Edstub207]

Describe the bug

We are using Minio which has S3 Functionality, by default the URL is minio.blah.randomurl.com/bucketname/, however, when we provide that URL the AWS S3 SDK falls over, it looks like other libraries (Java for example) allow you to use this bucket formatting with things like withPathStyleAccessEnabled but I can't see that on the AWS .net API__

Expected Behavior

Able to use either bucketname.minio.blah.randomurl.com/ or minio.blah.randomurl.com/bucketname/ as a URL for S3 Storage with the AWS API

Current Behavior

1: Prefixes the bucket name into the ServiceURL which doesn't resolve DNS as it doesn't exist

2: No bucket name is provided and an exception is thrown because a bucketname is a required field

System.ArgumentException: BucketName is a required property and must be set before making this call. (Parameter 'GetObjectRequest.BucketName')

@Edstub207 Good morning. Thanks for opening the issue. Are you able to use AmazonS3Config.ForcePathStyle property in AWS .NET SDK? Please confirm if it works for your use case.

Kindly note that we do not support using AWS .NET SDK with 3rd party AWS simulated services. SDK might work for certain scenarios, however, there are always some edge cases.

Thanks,
Ashish

@ashishdhingra thanks for the reply, an ex-colleague pointed me towards some reference code which I missed when looking into this and that's solved my problem!
