after converting C# to VB.NET there is an ambiguous error in the namespace

Question

there is an error I have marked in the code below whether this is the cause of converting from c# to vb.net but if I create a new project vb.net with the textbox there is no problem whatsoever. if I run the original C# project then without error. Please recommend a solution. is there anything that needs to be modified in the designer?

Thanks this may be an event issue in the vb.net
