Uri does not exist

  It looks like the update to FastReports.Net changed how assemblies are being referenced during compilation. If Uri is now being recognized under System.Net instead of System, you might try explicitly adding a using System; at the top of your code page or fully qualifying the call like System.Uri.EscapeDataString(myString). This can sometimes resolve issues where the compiler is picking up the wrong assembly reference.

  I have been using the Fast Report .NET Designer to generate the .rpt file. The code page always has default using statements. I had tried a combination of different attempts but still cannot seem to get EscapeDataString to work. I may just end up writing my own function for escaping the strings. Below are my attempts.

  -----

  using System;

  Uri.EscapeDataString(myString);

  
  

  This previews in the Designer but not from my API using FastReport.Net v 2025.1.16

  "Exception occurred: (21,15): Error CS0103: The name 'Uri' does not exist in the current context\r\n"

  -----

  using System;

  System.Uri.EscapeDataString(myString);

  
  

  This previews in the Designer but not from my API using FastReport.Net v 2025.1.16

  "Exception occurred: (21,15): Error CS1069: The type name 'Uri' could not be found in the namespace 'System'. This type has been forwarded to assembly 'System.Private.Uri, Version=0.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' Consider adding a reference to that assembly.\r\n"

  using System;

  using System.Private;

  System.Private.Uri.EscapeDataString(myString);

  
  

  In the Designer, 

  "Error CS0234: The type or namespace name 'Private' does not exist in the namespace 'System' (are you missing an assembly reference?)"

  From the API,

  "Exception occurred: (22,15): Error CS0234: The type or namespace name 'Uri' does not exist in the namespace 'System.Private' (are you missing an assembly reference?)\r\n"

  using System;

  using System.Net;

  Uri.EscapeDataString(myString);
