[PR_10128653]

Hi @gvyakaranam 

Did you find a Solution? how can we edit thingworx-common.dll files?

Hello @PR_10128653 ,

I have checked internally with our dev tem and it is neither advisable nor recommended to edit these OOTB files. However, the answer is yes you can edit ThingWorx-common.dll files. But if you decide to proceed editing these files, pls keep in mind that it may cause you upgrade and loss of existing projects. 

Also, What is the purpose of editing these file? pls share your issue so that we can work on the real problem. 

Have a good day ahead!

Regards

Bhawna

Hi @PR_10128653.

HI @slangley 

The Thingworx .Net SDK is not working in the .Net Framework 6 .

My Target .Net Framework version is  6 , is it TWX .Net SDK tested on .Net Framework 6?

Hi @PR_10128653.

I checked the Microsoft site for .Net Framework downloads and the latest one I found was 4.8.1.  The recommended version is 4.8.

Can you confirm the version of your o/s?  Where did you get .Net Framework 6?

Regards.
