The following error occurs when attempting convert a datatable to enumerable on

Argument ‘Value’: CS0012: The type ‘IXmlSerializable’ is defined in an assembly that is not referenced. You must add a reference to assembly ‘System.Xml.ReaderWriter, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a’.

The attached project includes a single assign activity that demonstrates the error.

Manually adding the assembly reference line to the xaml resolves the issue.

Hi there

I’ve been experiencing this issue for the past few weeks.

Thank you for your solution of manually adding the reference to the xaml - this saved me a lot of rework.

Thanks!

Hi, i am facing the same problem and i don´t know wich line did you add in the main xaml file

[Steven_Raines1 (Steven Raines)]

Open the xaml file with this error in a text editor.
Add <AssemblyReference>System.Xml.ReaderWriter</AssemblyReference> (without the quotes) within the <sco:Collection x:TypeArguments=“AssemblyReference”> element.

I’ve had this problem too. Is this a common problem or something UiPath is working on?

This fixed it for me, thanks! But just by looking at other entries under that element I think these ” ’ characters are not needed.
<AssemblyReference>System.Xml.ReaderWriter</AssemblyReference>

I’ve edited the post a bit and marked it as a solution. @Steven_Raines1 must have added the extra characters to get around the forum automatically sanitizing the HTML tags and making them invisible unless you use a code block.
