WEBVTT 1 00:00:00.390 --> 00:00:02.590 Hi, and welcome to this AI in C# 2 00:00:02.590 --> 00:00:07.230 video on the Agent Framework Toolkit, which 3 00:00:07.230 --> 00:00:10.290 is a set of NuGet packages that I 4 00:00:10.290 --> 00:00:14.370 have made that makes Agent Framework easier to 5 00:00:14.370 --> 00:00:15.210 work with. 6 00:00:15.750 --> 00:00:18.170 Today, we're going to look at easier agents. 7 00:00:19.690 --> 00:00:23.750 So the packages are up on NuGet, they're 8 00:00:23.750 --> 00:00:28.490 free, MIT, and are just a wrapper on 9 00:00:28.490 --> 00:00:30.430 top of the Agent Framework. 10 00:00:31.090 --> 00:00:34.370 You can choose whatever provider you want, Anthropic, 11 00:00:34.590 --> 00:00:37.610 Google, XAI, OpenAI, and so on. 12 00:00:40.680 --> 00:00:43.400 Or you can go and get the source 13 00:00:43.400 --> 00:00:44.460 code if you wish to. 14 00:00:46.480 --> 00:00:48.780 But let's see it in action on why 15 00:00:48.780 --> 00:00:52.540 it's worth adding this NuGet package compared to 16 00:00:52.540 --> 00:00:55.720 just using Microsoft Agent Framework by itself. 17 00:00:57.700 --> 00:01:01.300 So, I made a new one here called 18 00:01:01.300 --> 00:01:03.900 easier agents in our sample repo. 19 00:01:04.860 --> 00:01:06.640 And the first thing you will see is 20 00:01:06.640 --> 00:01:09.180 that you only need one NuGet package, not 21 00:01:09.180 --> 00:01:09.520 two. 22 00:01:10.120 --> 00:01:13.560 So the Azure OpenAI will, behind the scenes, 23 00:01:14.300 --> 00:01:17.040 reference the Azure OpenAI NuGet package, so you 24 00:01:17.040 --> 00:01:18.680 don't need to reference it yourself. 25 00:01:19.500 --> 00:01:22.160 So with this one NuGet package, you get 26 00:01:22.160 --> 00:01:23.040 everything you need. 27 00:01:25.490 --> 00:01:29.490 And the best way to show what it 28 00:01:29.490 --> 00:01:32.630 helps with is to actually just show you 29 00:01:32.630 --> 00:01:36.310 what you would do before you had this 30 00:01:36.310 --> 00:01:37.190 package. 31 00:01:38.530 --> 00:01:41.390 So if you had a task of you 32 00:01:41.390 --> 00:01:43.970 needed to take some weather data from a 33 00:01:43.970 --> 00:01:47.350 tool and put it out as structured output, 34 00:01:47.950 --> 00:01:51.370 you needed to call middleware, and you should 35 00:01:51.370 --> 00:01:55.050 use ChatGPT-mini with low reasoning effort. 36 00:01:56.630 --> 00:01:58.590 If you need to do that, we can 37 00:01:58.590 --> 00:02:02.810 see the tool is simple, and the weather 38 00:02:02.810 --> 00:02:05.990 report is just a structured output object. 39 00:02:08.740 --> 00:02:10.340 But in order for us to do this, 40 00:02:10.740 --> 00:02:14.420 we would get some credentials, that's normal. 41 00:02:14.920 --> 00:02:17.320 We would need to new up the Azure 42 00:02:17.320 --> 00:02:18.560 OpenAI client. 43 00:02:19.360 --> 00:02:22.100 We would need to make our agents. 44 00:02:22.920 --> 00:02:26.720 And because we wanted low reasoning, we need 45 00:02:26.720 --> 00:02:29.520 to do this special thing about chat options 46 00:02:29.520 --> 00:02:32.700 inside the chat client agent options with the 47 00:02:32.700 --> 00:02:36.980 chat client completion options to set this one 48 00:02:36.980 --> 00:02:37.780 property. 49 00:02:39.840 --> 00:02:42.980 We would set the tools as normal, but 50 00:02:42.980 --> 00:02:46.060 also because we want the function calling middleware, 51 00:02:46.060 --> 00:02:47.980 which is the code down here. 52 00:02:48.820 --> 00:02:51.100 We would need to do an as builder, 53 00:02:51.480 --> 00:02:54.580 use function calling middleware and build it. 54 00:02:55.080 --> 00:02:57.120 And we would end up with an AI 55 00:02:57.120 --> 00:03:00.040 agent, which is very bad for us when 56 00:03:00.040 --> 00:03:02.500 we need to do structured output, because an 57 00:03:02.500 --> 00:03:07.520 AI agent can't do run async with structured 58 00:03:07.520 --> 00:03:10.260 output like a chat client agent can do. 59 00:03:10.820 --> 00:03:13.440 So we would need to end up making 60 00:03:13.440 --> 00:03:15.340 some JSON serialisation options. 61 00:03:16.380 --> 00:03:19.720 We would need to, in our run async, 62 00:03:20.760 --> 00:03:23.500 put in yet another chat client agent options 63 00:03:23.500 --> 00:03:26.020 run here, in order to set the chat 64 00:03:26.020 --> 00:03:28.740 options, in order to set the response format 65 00:03:28.740 --> 00:03:32.540 to our weather report, which when we then 66 00:03:32.540 --> 00:03:35.540 get back, would need to deserialize with the 67 00:03:35.540 --> 00:03:39.680 serialisation options again, and finally have our output. 68 00:03:41.420 --> 00:03:45.120 So in total, we would need 84 lines 69 00:03:45.120 --> 00:03:48.440 of code, plus the tools and the objects. 70 00:03:50.120 --> 00:03:56.360 Let's see the exact same task in Agent 71 00:03:56.360 --> 00:03:57.160 Framework Toolkit. 72 00:03:58.000 --> 00:03:58.780 And here you have it. 73 00:03:59.900 --> 00:04:03.140 We do again get secrets, but instead of 74 00:04:03.140 --> 00:04:06.060 an Azure OpenAI client, we would make an 75 00:04:06.060 --> 00:04:09.480 Azure OpenAI agent factory, where we'll just give 76 00:04:09.480 --> 00:04:11.360 our endpoint and our API key. 77 00:04:13.190 --> 00:04:16.029 Then we'll use this agent to create an 78 00:04:16.029 --> 00:04:16.470 agent. 79 00:04:17.209 --> 00:04:20.850 We will take chat-gb5-mini, we'll just 80 00:04:20.850 --> 00:04:25.190 tell it slow, we'll tell the tools, and 81 00:04:25.190 --> 00:04:28.610 we'll put in the middleware directly here as 82 00:04:28.610 --> 00:04:29.190 an action. 83 00:04:32.780 --> 00:04:35.560 Then we'll get an Azure OpenAI agent, which 84 00:04:35.560 --> 00:04:38.480 is behind the scenes just a normal agent, 85 00:04:38.480 --> 00:04:40.000 so it's an inheritance. 86 00:04:41.540 --> 00:04:45.240 And that agent can do the wrong async, 87 00:04:45.640 --> 00:04:48.340 so we have the weather report directly out 88 00:04:48.340 --> 00:04:52.480 as a chat client agent response, despite we 89 00:04:52.480 --> 00:04:54.460 having the tool called middleware. 90 00:04:54.980 --> 00:04:57.400 And we would be done in 36 lines 91 00:04:57.400 --> 00:04:57.820 of code. 92 00:04:58.470 --> 00:05:01.720 So we'll have as many lines of code 93 00:05:01.720 --> 00:05:06.580 that are much easier to look at, and 94 00:05:06.580 --> 00:05:11.960 with the same features and functions, just easier, 95 00:05:12.520 --> 00:05:15.240 as the title of this video said. 96 00:05:16.720 --> 00:05:17.200 So we're done. 97 00:05:17.700 --> 00:05:18.580 See you on the next one.
