CSharp-NullableSolution

C# NullableSolution 1

We can simply make the properties nullable, as shown below:

public class AppSetting {
public string? ReferenceKey { get; set; }
public string? Value { get; set; }
public string? Description { get; set; }
}

Solution 2

We can assign a default value to those properties as shown below:

public class AppSetting {
public string ReferenceKey { get; set; } = “Default Key”
public string Value { get; set; } = “Default Value”
public string Description { get; set; } = “Default Description”
}

Alternatively, you can give a reasonable default value for non-nullable strings as string.empty.

Solution 3

You can disable this warning from project level. You can disable by removing the below line from project file csproj or setting.
