When Telerik UI for WinForms / WPF extensions are installed, Visual Studio is unresponsive for a couple of minutes after a solution is loaded. During that time, "Updating source control status…" is shown.

Workarounds:

• Disable Telerik UI for WinForms / WPF extensions.
• Checkout the solution file.

Remove warning in VS when creating a project using our VS template targeting .Net 6 / 7

We can update our extensions to honor the ImplicitUsings settings set globally for new projects. For the item templates, we will need to also check the project settings.

Below is the error.  I had removed all the references and was trying to add them back through the configure project extension vs 2019 and vs 2022 threw the same error. 

 

An error occurred while running the wizard.

Error executing custom action Telerik.WinControls.VSX.Actions.UpdateReferencesAction: System.Runtime.InteropServices.COMException (0x80004005): This reference cannot be removed from the project because it is always referenced by the compiler.

I upgraded to latest version of Win UI controls, and opened a project for an Outlook COM Addin. There has been no problems upgrading Telerik controls in that project until now. It's a Class Library project with Telerik forms in it. Now I have to change project type to Windows Forms, upgrade Telerik and then back to Class Library. Silly really... :)
