Names of interfaces must begin with I CS-R1010
Anti-pattern
Minor
The general consensus is that the names of interfaces begin with I. Doing so makes it clearer to the person reading the code that the type being dealt with is an interface thereby giving more context about the code-snippet.
Bad Practice
interface SampleInterface
{
void SampleMethod();
}
Recommended
interface ISampleInterface
{
void SampleMethod();
}
