ReSharper's support for MSTest has improved drastically over the past 5-6 months.
However, it still does not support the DeploymentItem attribute. It seems MSTest does not copy content specified to be copied to the output directory when it is run as a test. Neither does ReSharper. Instead, MSTest uses the DeploymentItem attribute, which ReSharper does not honor.
Is there any chance ReSharper could add support for this attribute?
