Compile Error conflict in records.cs but warnings only

Hi, I am creating an extension to get the tagimages from Amazon Rekognition. The code compiles OK in VS2017, but in integration studio 10.0.702 I get an error dispite the output only showing warnings. 

 AmazonRek.cs(33,170): warning CS0436: The type 'RCAmazonTokenRecord' in 'C:\dev\Outsystems\ImpXIF's\AmazonRek\Source\NET\Records.cs' conflicts with the imported type 'RCAmazonTokenRecord' in 'OutSystems.AmazonRek, Version=10.0.702.0, Culture=neutral, PublicKeyToken=null'. Using the type defined in 'C:\dev\Outsystems\ImpXIF's\AmazonRek\Source\NET\Records.cs'.

An ideas?

Can you retry after you change to a different local directory without the single quote?

kind regards,
