<summary>Determines whether the current type can be assigned to a variable of the specified <paramref name="targetType" />.</summary>

<returns><see langword="true" /> if any of the following conditions is true:

- The current instance and <paramref name="targetType" /> represent the same type.

- The current type is derived either directly or indirectly from <paramref name="targetType" />. The current type is derived directly from <paramref name="targetType" /> if it inherits from <paramref name="targetType" />; the current type is derived indirectly from <paramref name="targetType" /> if it inherits from a succession of one or more classes that inherit from <paramref name="targetType" />.

- <paramref name="targetType" /> is an interface that the current type implements.

- The current type is a generic type parameter, and <paramref name="targetType" /> represents one of the constraints of the current type.

- The current type represents a value type, and <paramref name="targetType" /> represents <c>Nullable&lt;c&gt;</c> (<c>Nullable(Of c)</c> in Visual Basic).

<see langword="false" /> if none of these conditions are true, or if <paramref name="targetType" /> or <see langword="this" /> is <see langword="null" />.</returns>
