Web Api Caching and resolving issues

I have a Web Api project with Telerik reporting, and a client Angular site that hosts the reportviewer.

The report files are compiled into the dll, ie. are not trdx files

I have had the following issues.

The initial call works and the report is displayed. However, subsequent calls just redisplay the initial report. I have verified this by changing the report and recompiling, as well as making changes in the database, yet the report does not change.

My ReportsController is

protectedoverrideIReportResolver CreateReportResolver()

{

returnnewReportTypeResolver();

}

protectedoverrideICache CreateCache()

{

returnTelerik.Reporting.Services.Engine.CacheFactory.CreateFileCache();

}

I tried to resolve this by overriding CreateStorage

protectedoverrideIStorage CreateStorage()

{

returnnewMsSqlServerStorage(@"Server=.\BF;database=Reporting;Integrated Security=true");

}

But when I do this I get a timeout exception when the report is being resolved

Error creating report instance (Report = NPS.Reports.Simple, NPS.Reports):
An error has occurred.
Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. The statement has been terminated.

I have the Fiddler trace as well as the SQL Server profiler trace, but cannot attach them so I have just attached screenshots.

The full exception is
