    Looking here: https://github.com/dotnet/corefx/bl...eLib/System/Collections/Generic/Dictionary.cs

    It sure seems like Dictionarys should work, but when I add anything even as simple as this:

    Code (CSharp):
    1. Dictionary<int, int> refsDict = new Dictionary<int, int>();
    I get:
    Code (CSharp):
    1. C:\Users\furroy\OneDrive\Documents\Krunk\Assets\Krunk\Scripts\TinyTileMapSystem.cs(40,57): error CS0246: The type or namespace name 'Dictionary<,>' could not be found (are you missing a using directive or an assembly reference?)

    Hi @furroy

    Dictionaries are not supported in the Tiny subset of .Net we need to use to keep the code size as small as possible. As an alternative, you can use 
    Unity.Collections.NativeHashMap
    .

    i thought that repo was the tiny .net core? why is there an implementation for Dictionary.cs in there if it's been removed?

    No, that repo is the class library for .NET Core. It's not related to the C# profile used by Tiny.

    @furroy the best way to figure out what is in the tiny corlib profile today is:

    a) by using Editor-Dots.sln and going by what intellisense tells you
    b) by observing the code that you can find here: Editor\Library\DotsRuntimeBuild\artifacts\Stevedore\il2cpp\mscorlib
