Re: In VS2022 designer, I get "Object reference not set to an instance of an object."

Hello,

apologies for the delay in our reply to you. Do you still have the Visual Studio project (*.csproj) you used to run your test with TeeChart? If so, could you please remove the binary files in the bin and obj directories, put it in a zip file, and post it here so I can test it here?
