Hi @KannanSuresh

Could you give this solution a try?

Hi @loginerror,

Thanks a lot for the quick reply.

I am aware of this workaround. However, this is not practical if we need to deploy some custom activities involving this nuget package.

Another workaround would be to repackage it and use.

It seems this is not an issue with UiPath. However, please note, this issue occurs when I try installing it on UiPath. It works without issues if I use it in a C# solution in Visual Studio.

Hi, did you ever come up with a good solution for this problem?

5

No. As of now repackaging is the only option I see.

Thats was what i did, sad thing this nugget package seems to be bad and having wrong dependencies…

It was installed. Thanks for giving this solution.
