Unable to load project in Visual Studio 2022 after update

Unable to load project or solution in Visual Studio 2022

Windows 10

After updating Visual Studio you are no longer able to load source files in your solution
Error message: Load failed, the project file cannot be loaded

The update has messed up you path settings as you have both 64bit and 32bit version of dotnet running

In the environment settings / system variables move the <drive>\program files\dotnet 64bit path above the <drive>\program files (x86)\dotnet 32bit path
Save and you are ready to use VS 2022 after having updated the platform to latest version

Open Control panel -> System and the Advanced System Settings

Choose Environment Variables

In System Variables edit the Path settings

Move the 64 bit dotnet path above the 32bit path

When done click Ok and restart VS 2022


Get document description using xmlreader

C# .NET Core 6: Get rootname, namespace or DTD using xmlreader

using (var stream = new MemoryStream())
	stream.Seek(0, SeekOrigin.Begin);

	var settings = new XmlReaderSettings()
		// Parse file but do not reolve
		DtdProcessing = DtdProcessing.Parse,
		XmlResolver = null

	using (var reader = XmlReader.Create(stream, settings))
		var done = false;

		while (reader.Read() && !done)
			// something weird happened, bail out
			//if (reader.EOF)
			//	return;

			switch (reader.NodeType)
				// Assume cXML
				case XmlNodeType.DocumentType:
					DocumentType = reader.GetAttribute("SYSTEM") + "";

				case XmlNodeType.Element:
					switch (reader.LocalName)
						// Assume an UBL dpcument of some kind
						case "CustomizationID":

						// Only OIOUBL, done and exit
						case "UBLlVersionID":
							UblVersion = reader.Value;
							done = true;

						// Only OIOXML, done and exit
						case "TypeCode":
							TypeCode = reader.Value;
							done = true;

							if (string.IsNullOrEmpty(RootName))
								RootName = reader.Name;

Validate EDI

Validate EDI (XML, Edifact and Ansi X12)  


  • Multiupload
    • No data is stored on the server
    • MIME type is detected based on file content
      • It is possible to upload without file extensiom
      • All other files than text (edifact / ansi x12) or xml are skipped / not supported
  • Validate structure (eg schema validation)
  • Validate business logic (eg schematron validation)
  • XSLT Styling, readable document in HTML
  • Calculate content and compare with values in eg an invoice


  • Multiupload based on Dropzone JS: https://www.dropzone.dev/
  • Implemented Mime-Detective in class factory: https://github.com/MediatedCommunications/Mime-Detective
  • Prepared and created concept to post files several times from Dropzone JS queue
    1. Upload to local client (browser) 
    2. Send file content to server to either
      1. Check and validate content
      2. Check business logic
      3. Style document
      4. Calculate prices and compare with document values
  • Use RaspConfiguration (Converted to JSON)

Current task

  • Cookie consent
  • AntiforgeyTokens
  • To scope the project only a few XML and EDIFACT versions will be implemented
    • OIOUBL (danish adaption of the UBL standard)
    • Peppol BIS
    • Standard eg EDIFACT D96 are considere in a limited version as a start as a proof of concept
    • cXML and xCBL are a possibility
  • Store messages in memory cache from validation methods and display in popup
  • XSLT transformations uses SaxonHE
    • All stylesheet versions are suported
    • Included stylesheets or XML documents are supported


  •  WIP
    • June 23: Only local test / development atm, date for a first beta release not estimated

To do list for project: 


Use local postman for testing?

Unit test
