// q2) Did GrantingAssembly name WantingAssembly as a friend via a strong name?
// q3) Is WantingAssembly strong-named?
// q4) Does GrantingAssembly give a strong-name for WantingAssembly that matches our strong name?
//
// Before we dive into the details, we should mention two additional facts:
//
// * If the answer to q1 is "yes", and GrantingAssembly was compiled by a Roslyn compiler, then q2 must be "yes" also.
// Strong-named GrantingAssembly must only be friends with strong-named WantingAssembly. See the blog article
// http://blogs.msdn.com/b/ericlippert/archive/2009/06/04/alas-smith-and-jones.aspx
// for an explanation of why this feature is desirable.
//
// Now, just because the compiler enforces this rule does not mean that we will never run into
// a scenario where GrantingAssembly is strong-named and names WantingAssembly via a weak name. Not all assemblies
// were compiled with a Roslyn compiler. We still need to deal sensibly with this situation.
// We do so by ignoring the problem; if strong-named GrantingAssembly extends friendship to weak-named
// WantingAssembly then we're done; any assembly named WantingAssembly is a friend of GrantingAssembly.
//
// Incidentally, the C# compiler produces error CS1726, ERR_FriendAssemblySNReq, and VB produces
// the error VB31535, ERR_FriendAssemblyStrongNameRequired, when compiling
// a strong-named GrantingAssembly that names a weak-named WantingAssembly as its friend.
//
// * If the answer to q1 is "no" and the answer to q3 is "yes" then we are in a situation where
// strong-named WantingAssembly is referencing weak-named GrantingAssembly, which is illegal. In the dev10 compiler
// we do not give an error about this until emit time. In Roslyn we have a new error, CS7029,
// which we give before emit time when we detect that weak-named GrantingAssembly has given friend access
// to strong-named WantingAssembly, which then references GrantingAssembly. However, we still want to give friend
// access to WantingAssembly for the purposes of semantic analysis.
//

// 1) If an unqualified, non-generic name didn't bind to anything and the name matches the name of the type

// 2) If a qualified, non-generic name didn't bind to anything and the LHS of the qualified name is a type

// Filtering out the case where specifying the name of a generic type without specifying
// any arity returns a constructor. This case shouldn't return anything. Note that
// returning the constructors was a fix for the wonky constructor behavior, but in order
// to not introduce a regression and breaking change we return NULL in this case.

//
// /// <see cref="Goo"/>
// class Goo<T> { }

// since there was no arity, it didn't find Goo<T>. Now however, it finds Goo<T>.ctor,
// which is arguably correct, but would be a breaking change (albeit with minimal impact)
// so we catch this case and chuck out the symbol found.
// In Roslyn, we're doing everything in one pass, rather than guessing and rolling back.

// public void M(Inner i) { }
//
// /// <see cref="M"/>
// /// <see cref="C{T}.M"/>

// public void N() { }

//
// Dev12 binds all of the crefs as "M:C`1.M(C{`0}.Inner)".
// Roslyn accepts all but the last. The issue is that the context for performing
// the lookup is not C<Q>, but C<T>. Consequently, Inner binds to C<T>.Inner and
// then overload resolution fails because C<T>.Inner does not match C<Q>.Inner,
// the parameter type of C<Q>.M. Since we could not agree that the old behavior
// was desirable (other than for backwards compatibility) and since mimicking it
// would have been expensive, we settled on introducing a new warning that at
// least hints to the user how then can work around the issue (i.e. by qualifying
// Inner as C{Q}.Inner). Additional details are available in DevDiv #743425.
//
// CONSIDER: We could actually put the qualified form in the warning message,
// but that would probably just make it more frustrating (i.e. if the compiler

// Dev12 binds all of the crefs as "M:C`1.M(C{`0}.Inner)".
// Roslyn accepts all but the last. The issue is that the context for performing
// the lookup is not C<Q>, but C<T>. Consequently, Inner binds to C<T>.Inner and

// least hints to the user how then can work around the issue (i.e. by qualifying

// SPEC: operators declared in the same class.
// DELIBERATE SPEC VIOLATION:
// The specification does not state that a user-defined conversion reserves the names
// op_Implicit or op_Explicit, but nevertheless the native compiler does so; an attempt
// to define a field or a conflicting method with the metadata name of a user-defined
// conversion is an error. We preserve this reasonable behavior.
//
// Similarly, we treat "public static C operator +(C, C)" as colliding with
// "public static C op_Addition(C, C)". Fortunately, this behavior simply
// falls out of treating user-defined operators as ordinary methods; we do
// not need any special handling in this method.
//
// However, we must have special handling for conversions because conversions
// use a completely different rule for detecting collisions between two
// conversions: conversion signatures consist only of the source and target
// types of the conversions, and not the kind of the conversion (implicit or explicit),
// the name of the method, and so on.
//
// Therefore we must detect the following kinds of member name conflicts:
//
// 1. a method, conversion or field has the same name as a (different) field (* see note below)
// 2. a method has the same method signature as another method or conversion
// 3. a conversion has the same conversion signature as another conversion.
//
// However, we must *not* detect "a conversion has the same *method* signature
// as another conversion" because conversions are allowed to overload on
// return type but methods are not.
//
// (*) NOTE: Throughout the rest of this method I will use "field" as a shorthand for
// "non-method, non-conversion, non-type member", rather than spelling out
// "field, property or event...")

// * a field directly following a field
// * a field directly following a method or conversion

// Furthermore: we do not wish to detect collisions between nested types in

// The specification does not state that a user-defined conversion reserves the names
// op_Implicit or op_Explicit, but nevertheless the native compiler does so; an attempt
// to define a field or a conflicting method with the metadata name of a user-defined
// conversion is an error. We preserve this reasonable behavior.
//
// Similarly, we treat "public static C operator +(C, C)" as colliding with
// "public static C op_Addition(C, C)". Fortunately, this behavior simply
// falls out of treating user-defined operators as ordinary methods; we do
// not need any special handling in this method.
//
// However, we must have special handling for conversions because conversions
// use a completely different rule for detecting collisions between two
// conversions: conversion signatures consist only of the source and target
// types of the conversions, and not the kind of the conversion (implicit or explicit),
// the name of the method, and so on.
//
// Therefore we must detect the following kinds of member name conflicts:
//
// 1. a method, conversion or field has the same name as a (different) field (* see note below)
// 2. a method has the same method signature as another method or conversion
// 3. a conversion has the same conversion signature as another conversion.
//
// However, we must *not* detect "a conversion has the same *method* signature
// as another conversion" because conversions are allowed to overload on
// return type but methods are not.

// (*) NOTE: Throughout the rest of this method I will use "field" as a shorthand for
// "non-method, non-conversion, non-type member", rather than spelling out
// "field, property or event...")

// * a field directly following a method or conversion

// Furthermore: we do not wish to detect collisions between nested types in

' Floating point values might be represented either in fixed point notation or scientific/exponent notation.
' MSDN comment for Standard Numeric Format Strings used in Single.ToString(String) API (or Double.ToString(String)):
' Fixed-point notation is used if the exponent that would result from expressing the number in scientific notation is greater than -5 and
' less than the precision specifier; otherwise, scientific notation is used.
'
' However, Dev11 pretty lister differs from this for floating point values < 0. It uses fixed point notation as long as exponent is greater than '-(actualPrecision + 1)'.

' (i) Precision = 7
