Hi , just a quick question: Is the library thread safe?

Dror

Below is the stack trace. What could be the reason?

Started a new .net 6 console application. No code. Attempted to install the nuget package.
Have tried for a few versions previous too.

I was trying to run an example for data writing. It failed with the exception below.

Message: "Collection was modified; enumeration operation may not execute."

There is a problem with the following code:

63: foreach (var label in variable.ValueLabels)
64:     variable.ValueLabels[label.Key] = TrimMaxLength(label.Value, 120)!;

You cannot do it this way. Just label.Value = TrimMaxLength(label.Value, 120)!; would work fine.

Is it possible to change the project type to .netstandard2.0, which will make the packages useable in .NET Framework projects also?

Would it be possible to add support for .netstandard 2.0?
