MenuStrip不允许创建菜单

Question

我使用的是visual studio 2019，我创建了一个windows form app项目。在表单中，当我放置MenuStrip时，它不会向我显示Type here to create menus的框。我在网上找过了，但没有找到任何答案。有人能帮我吗？提前谢谢。

// Form1.Designer.cs

namespace asg_gui_F
{
    partial class Form1
    {
        /// <summary>
        /// Required designer variable.
        /// </summary>
        private System.ComponentModel.IContainer components = null;

        /// <summary>
        /// Clean up any resources being used.
        /// </summary>
        /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
        protected override void Dispose(bool disposing)
        {
            if (disposing && (components != null))
            {
                components.Dispose();
            }
            base.Dispose(disposing);
        }

        #region Windows Form Designer generated code

        /// <summary>
        /// Required method for Designer support - do not modify
        /// the contents of this method with the code editor.
        /// </summary>
        private void InitializeComponent()
        {
            this.menuStrip1 = new System.Windows.Forms.MenuStrip();
            this.SuspendLayout();
            // 
            // menuStrip1
            // 
            this.menuStrip1.Location = new System.Drawing.Point(0, 0);
            this.menuStrip1.Name = "menuStrip1";
            this.menuStrip1.Size = new System.Drawing.Size(800, 24);
            this.menuStrip1.TabIndex = 0;
            this.menuStrip1.Text = "menuStrip1";
            // 
            // Form1
            // 
            this.AutoScaleDimensions = new System.Drawing.SizeF(7F, 15F);
            this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
            this.ClientSize = new System.Drawing.Size(800, 450);
            this.Controls.Add(this.menuStrip1);
            this.Name = "Form1";
            this.Text = "Form1";
            this.ResumeLayout(false);
            this.PerformLayout();

        }

        #endregion

        private System.Windows.Forms.MenuStrip menuStrip1;
    }
}

Answer 1

确保在创建项目时选择"Windows Forms App (.Net框架)“，您将看到"Type here”。

Answer 2

解决了这个问题，在创建表单时使用.netframework而不是核心

Answer 3

此问题已在Visual Studio最新版本v16.10: 05/25/2021 (https://docs.microsoft.com/en-us/visualstudio/releases/2019/release-notes)中修复。我已经在net 5(当前版本)和net Core3.1 (LTS)中对此进行了测试。
