# SSRShas no direct NuGet - it's server-based
# Remove any ReportViewer controls

dotnet remove package Microsoft.ReportingServices.ReportViewerControl.WebForms
dotnet remove package Microsoft.ReportingServices.ReportViewerControl.WinForms

# Install IronPDF
dotnet add package IronPdf

// Add at application startup
IronPdf.License.LicenseKey = "YOUR-LICENSE-KEY";
