Stable Diffusion Library for .NET
Get Started
$ dotnet add package OnnxStack.StableDiffusionReadme
OnnxStack.StableDiffusion - Onnx Stable Diffusion Services for .NET Applications
OnnxStack.StableDiffusion is a library that provides higher-level Stable Diffusion services for use in .NET applications. It offers extensive support for features such as dependency injection, .NET configuration implementations, ASP.NET Core integration, and IHostedService support.
Getting Started
.NET Core Registration
You can easily integrate OnnxStack.StableDiffusion into your application services layer. This registration process sets up the necessary services and loads the appsettings.json configuration.
Example: Registering OnnxStack.StableDiffusion
builder.Services.AddOnnxStackStableDiffusion();
