How can I see and select the Vertex of the Mesh in Weight Painting Mode in Blender 2.8? I dislike the brush for the weight painting, I want to be able to select vertex and add the amount of weight I want manually. That's something I can do on blender 2.7 but not in blender 2.8, I can't even see the wireframe of the model in blender 2.8 while doing the weight painting.
I'm not sure what you're referring to in 2.7 but in 2.8 you can display the wire with the Viewport Overlay > Wire option, and if you switch to Edit mode you can select a vertex then in the N panel > Item > Vertex Weights, set the weight you want.
