ReSharper's analysis of interface names could be slightly improved. Consider the following interface:

public interface InstanceInterceptor {}

Assuming an interface naming style of a PascalCase name with a prefix of "I", R# will suggest the name "INstanceInterceptor" instead of "IInstanceInterceptor". Perhaps in cases where the naming style follows the pattern PPascalCaseName, where "P" is a wholly alphabetical prefix in all caps, R# should assume that a missing prefix is more likely than a camelCased name. At the very least, both names should be presented in the suggestion list.
