How can I use two parameters while one inherits from IProject and other has a new() constraint? The following doesn't pass compilation with the "Cannot create an instance of the variable type 'T' because it does not have the new() constraint" error.
public static T CreateNewProject<T, V>(string token, string projectName) where V : IProject<T>, T new()
{
T project = new T();
}
If you want to apply constraints to multiple parameters, then you need to add second where
as:
where V : IProject<T>
where T : new()
And also, you need to return something from your method:
public static T CreateNewProject<T, V>(string token, string projectName)
where V : IProject<T>
where T : new()
{
return new T();
}
PS: For applying new
constraint, the type argument must have a public parameterless constructor.
