Integrate roslyn

[apexdodge]

Proof of concept showing how roslyn can be given access to the entire Application layer. This is insanely powerful if we add a feature that allows system admins to add their own code.

Examples:

• Receive an HTTP Post, save data to db, and then send an email notification.
• Receive an HTTP Post, make an API call to an external service

    [Route(RAYTHA_ROUTE_PREFIX + "/roslyn", Name = "roslyn")]
    public async Task<IActionResult> Roslyn()
    {
        Globals g = new Globals 
        {
            Emailer = Emailer,
            Mediator = Mediator
        };
        var scriptOptions = ScriptOptions.Default
            .WithReferences(typeof(GetDashboardMetrics.Query).Assembly)
            .WithImports("System") 
            .WithImports("System.Threading.Tasks")
            .WithImports("Raytha.Application.Dashboard.Queries")
            .WithImports("Raytha.Application.ContentItems.Queries");

string script = @"
var result = await Mediator.Send(new GetContentItemById.Query { Id = ""x37LR9WiMESkii46Y-OAuA"" });
result
";

        var scriptResult = await CSharpScript.EvaluateAsync(script, scriptOptions, g);
        return Ok(scriptResult);
    }
