I am following a the tutorial from 2d vector from godot docs and i am running the following script through c#:
using Godot;
using System;

public class Node2D : Godot.Node2D
// Declare member variables here. Examples:
// private int a = 2;
// private string b = “text”;

// Called when the node enters the scene tree for the first time.
public override void _Ready()

public override void _Process(float delta)
var Node2D = (Node2D)GetNode(“Node2D”);
Node2D.Position=new Vector2(400,300);
But when i am running the scene or building its giving me the following errors:
C:\Users\MANDAL.nuget\packages\\3.3.0\Sdk\Sdk.props(29,11): The SDK ‘Microsoft.NET.Sdk’ specified could not be found.

C:\Program Files (x86)\Microsoft Visual Studio\2019\BuildTools\Common7\IDE\CommonExtensions\Microsoft\NuGet\NuGet.targets(131,5): Unable to find a project to restore!

F:\GODOT PROJECTS\PRACTICE\Practice.csproj(0,0): Skipping restore for project ‘F:\GODOT PROJECTS\PRACTICE\Practice.csproj’. The project file may be invalid or missing targets required for restore.

The error is not caused by your code, otherwise by the missing build tools. Here you have a link to a installer.

Thank you for you help… i have installed msbuild and mono both after this… do I have to change the build in mono section of editor settings?(I have dotnet CLI by default and changing it to anything else also giving me errors)…
I have installed mono (and changed the build in settings after a restart )but i am still getting error like this.(in the msbuild window below)

F:\GODOT PROJECTS\VEctro\VEctro.csproj(0,0): The SDK resolver type “DotNetMSBuildSdkResolver” failed to load. The type initializer for ‘Microsoft.DotNet.MSBuildSdkResolver.VSSettings’ threw an exception.

and in the debugger window getting these errors when build are set to dotnetCLI:
E 0:00:02.272 get_node: (Node not found: “Node2D” (relative to “/root/Node2D”).)

Thank you for helping me as i am very new to this and these errors are really demoralizing as I dont have any clue what is the source of the problem

Thank you once again for you help
