XSLT compile error-PlatformNotSupportedException: Compiling JScript/CSharp scripts is not supported

Question

Hi Team,

I am calling an xslt in console application, the xslt has cdata section having a function. using cdata is causing the below issue, not calling any function in xslt is working as expected.

below is the console application code-

using System;
using System.Collections.Generic;
using System.Text;
using System.Net;
using System.Xml;
using System.Xml.Xsl;

using System.IO;

namespace ConsoleApp1
{
class Class3
{
public static void Main()
{
StringBuilder stringBuilder = new StringBuilder();
XslCompiledTransform xslt = new XslCompiledTransform();
XmlWriterSettings settings = new XmlWriterSettings();
XsltSettings xslt_setting = new XsltSettings();
xslt_setting.EnableScript = true;
settings.OmitXmlDeclaration = true;
settings.ConformanceLevel = ConformanceLevel.Fragment;
settings.CloseOutput = false;

        string xml_string = System.IO.File.ReadAllText("xmlpath");  
        string xslt_string = System.IO.File.ReadAllText("xslt path");  

                        byte[] byteArray = Encoding.UTF8.GetBytes(xslt_string);  
                        var tmpFile = Path.GetTempFileName();  
                        var tmpFileStream = System.IO.File.OpenWrite(tmpFile);  
                        tmpFileStream.Write(byteArray, 0, byteArray.Length);  
                        tmpFileStream.Close();  
                        
                        xslt.Load(tmpFile, xslt_setting, null);  
                        
                        byte[] byteArray1 = Encoding.UTF8.GetBytes(xml_string);  
                        var tmpFile1 = Path.GetTempFileName();  
                        var tmpFileStream1 = System.IO.File.OpenWrite(tmpFile1);  
                        tmpFileStream1.Write(byteArray1, 0, byteArray1.Length);  
                        tmpFileStream1.Close();  
                        xslt.Transform(tmpFile1, XmlWriter.Create(stringBuilder, settings));  
                    }  
                   
                }  
            }  

and error message is:

.net framework -.net core tool 3.1

Please help to resolve this issue

Note that, according to documentation, “Script blocks are supported only in .NET Framework. They are not supported on .NET Core or .NET 5.0 or later”. Try creating a new “Console App (.NET Framework)” project.
