In October 2024, Microsoft announced the Microsoft.Extensions.AI.Abstractions and Microsoft.Extensions.AI libraries for .NET. These libraries provide the .NET ecosystem with essential abstractions for integrating AI services into .NET applications from various providers such as Open AI, Azure, Google.

Today, we’re happy to announce the Google.Cloud.VertexAI.Extensions library. This is the Vertex AI implementation of Microsoft.Extensions.AI. It enables .NET developers to integrate Google Gemini models on Vertex AI via the Microsoft.Extensions.AI abstractions.

Let’s take a look at the details.

Last year, we announced the Google Gen AI SDK as the new unified library for Gemini on Google AI (via the Gemini Developer API) and Vertex AI (via the Vertex AI API). At the time, it was only a Python SDK. Since then, the team has been busy adding support for Go, Node.js, and Java but my favorite language, C#, was missing until now.

Today, I’m happy to announce that we now have a Google Gen AI .NET SDK! This SDK enables C#/.NET developers use Gemini from Google AI or Vertex AI with a single unified library.

A user recently reported an intermittent error with C# and Gemini 1.5 model on Vertex AI’s streaming API. In this blog post, I want to outline what the error is, what causes it, and how to avoid it with the hopes of saving some frustration for someone out there.

Error

The user reported using Google.Cloud.AIPlatform.V1 library with version 2.27.0 to use Gemini 1.5 via Vertex AI’s streaming API and running into an intermittent System.IO.IOException.

.NET 7 was released a few days ago with new features and performance improvements and it’s already supported on Cloud Run on Google Cloud!

In this short blog post, I show you how to deploy a .NET 7 web app to Cloud Run.

Create a .NET 7 web app

First, make sure you’re on .NET 7:

dotnet --version
7.0.100

Create a simple web app:

dotnet new web -o helloworld-dotnet7

This creates the helloworld-dotnet7 folder with a project file. I love how simple the default Program.cs file is nowadays:

.NET for Google Cloud Functions (Alpha)

I spoke at many .NET conferences over the last 3-4 years and one of the top requests I always received was: When will .NET be supported on Cloud Functions?

Unfortunately, I didn’t have a good answer for a while. That all changed last month with the following tweet from Jon Skeet from our C# team:

I'm thrilled that .NET support is coming to Google Cloud Functions, along with the .NET Functions Framework. Sign up for the public alpha at https://t.co/nASIACFCrg

.NET Core 3.1 updates on Google Cloud

.NET Core 3.1 was released on December 3rd, 2019 and is a LTS release, supported for three years.

In Google Cloud, you could already deploy .NET Core 3.1 containers in Cloud Run (see cloud-run-dotnetcore-31) and also in App Engine flexible environment with a custom runtime.

We recently extended .NET Core 3.1 support in a couple of ways:

1. Cloud Shell now supports .NET Core 3.1.
2. App Engine flexible environment runtime now supports .NET Core 3.1.

.NET Core 3.1 in Cloud Shell

Inside Cloud Shell, you can see the latest 3.1.301 version:

Introduction

Until recently, there were two distinct camps in the software world: the Windows (A.K.A. closed) world and the Linux (A.K.A. open) world. In the Linux world, we had tools like the bash shell, Java programming language, Eclipse IDE, MySQL database, and many other open-source projects by Apache. In the Windows world, we had similar, yet distinct tools mainly developed by Microsoft, such as the C# programming language, Visual Studio IDE, SQL Server and PowerShell.
