❔ ✅ CS0116 [SOLVED]

and CS1061: 'Form1' does not contain a definition for 'button1_Click' and no accessible extension method 'button1_Click' accepting a first argument of type 'Form1' could be found (are you missing a using directive or a assembly reference?) I'm just making a installer and i'm a C# beginner so I don't know how to fix this

Methods go into classes Classes go into namespaces Seems like your titular error is because some of your methods have been placed in a namespace

Make sure you format your code properly so you can see where each class and method starts and ends $prettycode

To format your code in Visual Studio, Visual Studio Code, Rider, use the following shortcut:
Visual Studio CTRL + K + D
Rider / Resharper CTRL + ALT + L
Visual Studio Code SHIFT + ALT + F
Visual Studio CTRL + K + D
Rider / Resharper CTRL + ALT + L
Visual Studio Code SHIFT + ALT + F
NOTE: the first key must be held while doing it. https://cdn.discordapp.com/attachments/569261465463160900/899513918567890944/2021-10-18_01-26-35.gif

idfk man maybe both

This example shows most of what can be in a file, but not everything has to be there The stripped down version would be
namespace Namespace
{
public class Class
{
public void Method()
{

}
}
}
namespace Namespace
{
public class Class
{
public void Method()
{

}
}
}
So, in short, make sure that - Your class is within the namespaces braces ({}) or make sure the namespace is file-scoped, so ends with a semicolon (;) and doesn't have braces - All your methods are within the class's braces Prettyinfying your code will help you see whether or not everything is correct It's easier to spot the error when your code isn't
class Animal
{
public void Bark() {

}
}
}
class Animal
{
public void Bark() {

}
}
}
but
class Animal
{
public void Bark()
{

}
}
}
class Animal
{
public void Bark()
{

}
}
}
instead You immediately see you have one } too many
