Thanks for your response.
Regarding Trumbowyg:
we downloaded the code and compile in our machine. the code was not build properly as we are used the .Net framework 4.6. I think downloaded code was build on top of .Net framework 4.7 and above.
Could you please provide any sample code which has build on top of .Net framework 4.6 and older version.
If so please provide the link for download the source code.
