Parameter matching for resolving function overloads has an issue

[KanishManuja-MS]

There is a bug in the way we match URI parameters to function parameters. For case-insensitive matching, the same parameter in the URI can be used to match with multiple parameters in the function's uri. It is uncommon for functions to have the same name for parameters but it is possible.

odata.net/src/Microsoft.OData.Core/Metadata/EdmLibraryExtensions.cs

Line 1819 in c8a25ab

private static bool ParametersSatisfyFunction(IEdmOperation operation, IList<string> parameterNameList, bool caseInsensitive)

Assemblies affected

Which assemblies and versions are known to be affected e.g. OData .Net lib 7.x
ODL 7.x

Reproduce steps

Add a function that takes two parameters that have the same name but only differ in case. Specify only one parameter in the request. The function will be considered a match if it is the only function.

Expected result

The function should not be considered a match.

Actual result

The function is considered a match.
