MissingMethodException: how to add References with HotFix

[tr888]

I think I have done this incorrectly. Are there two hotfixes, one for Spire.Pdf and one for Spire.PdfViewer? Please advise. I cannot find Viewer hotfix, if there is one. Would latest eval incorporate it?

I have downloaded the HotFix spire.pdf_3.7.198 and copied these files

Spire.License.dll
Spire.License.xml
Spire.Pdf.dll
Spire.Pdf.XML

into the folder for the commercial eval of Spire.Pdf:

C:\Program Files (x86)\e-iceblue\Spire.Pdf\Bin\NET4.0

In my project, I reference the Spire.License.dll and the Spire.Pdf.dll from the folder above, and I also reference Spire.PdfViewer.Forms.dll from the folder for the commercial evaluation of that product.

Now, when I run the project, it crashes with a MissingMethodException at

var VIEWER = new Spire.PdfViewer.Forms.PdfDocumentViewer();


Here are the details:

System.MissingMethodException: Method not found: 'System.Drawing.Rectangle sprᬰ.ᜄ()'.

Dear tr888,

Thanks for your inquiry.
Please note that alone two libraries can't be used in the same project, and if you want to use two or more Spire's products into same project , you must use Spire.Office and then reference corresponding dlls from it.

Sincerely,
Betsy
