Uri does not exist

SafeTK

I have a report that grabs images from Azure Blob Storage. It was working just fine until I updated to FastReports.Net 2025.1.6. I just tested with FastReports.Net 2025.2.4 and the same thing is happening.

In my Code page, I have a function:

public string EscapeString(string myString)      

  {

    return Uri.EscapeDataString(myString);

  }  

Through some research, during Compile, it looks like AddStubClasses in MsAssemblyDescriptor shows that Uri belongs to System.Net instead of System.

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);

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

using System;

System.Uri.EscapeDataString(myString);

using System;

using System.Private;

System.Private.Uri.EscapeDataString(myString);

In the Designer,

From the API,
