Error saying haven't got 'System.Drawing.Common, Versions=4.0.0.1' - WinForm VB.net #924
Description
Hi Scott, this is a bit of a curly question, as I don't know why things are happening this way.
Some slight background on this, as it has happened before with my current app instance...
I am working on a program using VS 16.9.2, and my program is a VB.NET Winform app, rather than using C#.
My program has been working fine, but then when I try and add a SP chart to the program, I get a nice little ambiguous error.
I can add SP and SP.WinForms through NuGet and it adds tem to the application fine, but, when I try to add a SP chart to a form, I get a popup message, telling me that I haven't got 'System.Drawing.Common, Versions=4.0.0.1' etc installed...
I know that I'm fulfilling the requirements of SP, as I have version 4.0.0.2 installed, and the latest version of SP as well. (4.0.48)
So, I did some testing and recreated the project like before using .NET Framework 4.7.2, (fortunately it's only a single form application so it's not too hard), and it all worked and I was able to add SP items. However, since then I have been using it, I am once again having the same error appear
The thing is the error is now in a different place when I try to open up the Design view of my form.
I saw that someone else had a similar problem, but not exactly: #655
Do you have any suggestions, or know why it would work, and then after a while decide to not want to load the Design view?
Here's a screen shot of the error, along with the text as well.
To prevent possible data loss before loading the designer, the following errors must be resolved:
Could not load file or assembly 'System.Drawing.Common, Version=4.0.0.1, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51' or one of its dependencies. The system cannot find the file specified.
