Issues after upgrade to .net 4.8

[Michael Højgaard Bojsen]

Hi all

After upgrading to 4.8 we are seeing a "Class already exists" with the stacktrace below.

It looks like it happens in the instantiation of the RichTextBox, but besides that I do not find anything usable for me.

Best regards

Michael

Hi,

Firefly works with .NET 4.8.

With regards to your error, you only included the call stack, and not the error itself - try adding it and maybe it'll include more clues.

Hi,

 

See also my reply of 19 September 2021:

 

Just FYI, I did had an issue with migrating to .NET 4.8. The Target Framework of the FireFly.Box was 3.5. If you upgrade this too then you might run into a security issue that was introduced since .NET 4.0.

To solve this you only have to disable (/comment out) the [assembly: AllowPartiallyTrustedCallers] in the AssemblyInfo.cs.

 

Best regards,

Harry Kleinsmit.

Hi, 

To fix that, go to the file:

Firefly\UI\RichTextBoxEx.cs

And change UseVersion41 to false in the constructor of RichTextBoxV5 class

This bug was fixed in 2019.

That flag only applies to customers who migrated from older versions of magic (v9 etc...)

Hi Noam

That worked! Thank you for your help.
