Hi Rajat ,

did you make sure to set the data type of the binary date in the entity ? 

I had the same issue, didn't have any time find to correct the solution properly. I just needed the binary file (for an image), so modified the solution to handle my immediate needs.

I found the issue was related to he lines below I never needed a filename, so I just hardcoded a filename, and I commented out ContentDisposition, which was causing the null reference.

You can find the problem around lines 95/96 of BinaryDownload.cs

//           ContentDisposition cDispo = new ContentDisposition(response.Headers.GetValues("Content-Disposition")[0]);
                        ssFileName = "DownloadedFile";// cDispo.FileName;

If someone has time to look into the issue further, this is a handy component.

I had the same error and resolved as mark said.

I think it will be enough to do an extra validation because in that context sometimes we don't have the Headers to get that specific value.

Otherwise a default filename should be returned.

Hey guys,

I apoligize for not seeing this sooner. I’ll take a look at the component tommorow.

Do you have an url I can test with? Feel free to PM me.

Expect some update tommorow.
