I'm finding a lot of threads about how to disable report caching in Visual Studio, but I'm having the opposite problem. Every time I make a minor adjustment to a report in Visual Studio and then preview it, it is executing the query again and creating a new .data file, even though I'm not changing any parameters. I want the data to be cached so that the preview opens right away, instead of waiting 20 seconds for the SP to execute.
My reports are for SQL 2008 R2. I'm having this problem with both BIDS in Visual Studio 2008 and SSDT in Visual Studio 2010. I have checked my RSReportDesign.config file and the value for CacheDataForPreview is true.
Any suggestions for how to get my preview to use the cached data would be appreciated!
