Missing Microsoft.ReportViewer.NETCore.XmlSerializers assembly issue when running in .net 7.

[3grkt]

I've updated ReportViewerCore.NETCore to the latest version (15.1.19) but still having the error when setting the parameters (report.SetParameters). And I don't find XmlSerializers in the repo. System.IO.FileNotFoundException: 'Could not load file or assembly 'Microsoft.ReportViewer.NETCore.XmlSerializers, Version=15.1.19.0, Culture=neutral, PublicKeyToken=null, processorArchitecture=MSIL'. The system cannot find the file specified.'

Would you please advise what should be the issue here?

I don't recall there ever being Microsoft.ReportViewer.NETCore.XmlSerializers assembly in either this or original report viewer. Why did you reference such assembly?

Thank you for looking at this. I didn't reference to the assembly explicitly. I'm just getting this exception when it gets to SetParameters() method in consuming the report services. ServerReport serverReport = new ServerReport(); serverReport.ReportServerUrl = new Uri(reportServer.Uri); serverReport.ReportPath = resourcePath; //exception happens at the below method. serverReport.SetParameters(new List() { new ReportParameter("ServerName", dataSource.ServerName), new ReportParameter("DatabaseName", dataSource.DatabaseName) }); return new MemoryStream(serverReport.Render("Pdf"));

Oh, that one. It's related to webservices used to communicate with Reporting Service. You should be able to continue past this exception - it is caught and handled internally by .NET WSDL client.

Thank you for your help. There were some issues along with that, but you are right that when I was debugging, it threw that exception but when I kept going for 3-4 times, it was getting through. Thanks again.
