0.7.2

Fixed

    • Allows Grid2ds to support construction from Grid1ds that are not straight lines. Previously Grid1ds could support any sort of curve and Grid2ds were stuck as dumb rectangles.
  • JsonInheritanceConverter
    • Makes the Type Cache on the JsonInheritanceConverter static, and exposes a public method to refresh it. In the grasshopper context, new types may have been dynamically loaded since the JsonInheritanceConverter was initialized, so it needs to be refreshed before deserializing a model.

      • GenerateCodeFromSchema() produces csharp from a schema, including generating the namespace, typename, and local excludes
      • GenerateCompilation() takes the csharp and compiles it, using a new optional flag frameworkBuild to designate whether it should load netstandard or net framework reference assemblies.
      • EmitAndLoad() generates the assembly in memory and loads it into the app domain.
    • Adds an EmitAndSave() method that generates the assembly and writes it to a .dll on disk
    • Adds a public GenerateAndSaveDllForSchema() method used by grasshopper that generates code from a schema, generates a compilation, and saves it to disk as a DLL.
