Hi,

After using Wisej-4.UpgradeTool and upgrading nuggets from Wisej-3* to Wisej-4*, my project is running ok.

I’m using VS 2022; in designer many Forms crash on opening with: Method not found: ‘System.Drawing.SizeF System.Drawing.Graphics.MeasureString(System.String, System.Drawing.Font, System.Drawing.SizeF, System.Drawing.StringFormat)’.

 

Please advice

Go to Extensions / Manage Extensions / Installed
Select Wisej.NET and Uninstall
Close VS to let the uninstall run
Download from https://wisej.com/builds
Run the VSIX

Done.

    Hi Frank. After a long weekend, I installed Visual Studio 2026 and Wisej4 extension. Now it’s working everything. If possible, I’d like to repair somehow Visual Studio 2022; if you find a way please inform me. Thank you for your support.

It seems that something is really messed-up on my pc. Look what’s happening when, in a new wisej 4 project, I tried to drad&drop an upload control on windows surface. Please advice.

Hi Adrian,

project opens fine here.

As written in the comment:
Please uninstall Wisej.NET 4.0.5 via Manage Extensions.
Redownload from https://wisej.com/builds
Install that version

Best regards
Frank

Hi Adrian,

if you installed from the VS Marketplace please do the following:

Uninstall Wisej.NET Extension.
Download from https://wisej.com/builds/
Install the VSIX from there.

4.0.5 in the marketplace has some issues and we are currently working on resolving them.

Best regards
Frank

    It’s installed from your link already.

    Can you please try to redownload and repeat the steps? Regards, Frank
  • Adrian Zagar
    I can provide you one of the forms with that problem and you can test it yourself. If you have a vsix file that works on it, please send it .

    See above.
