###  .ctor

Initializes a new instance of the [ODataMcpSessionFactory](https://ai.easyaf.dev/odata-mcp/api-reference/Microsoft/OData/Mcp/AspNetCore/Hosting/ODataMcpSessionFactory.md) class.

#### Syntax

```csharp theme={null}
public ODataMcpSessionFactory(System.IServiceProvider services, Microsoft.Extensions.Options.IOptions<Microsoft.OData.Mcp.AspNetCore.Hosting.ODataMcpHostOptions> hostOptions, Microsoft.OData.Mcp.AspNetCore.Hosting.ODataMcpPipeline pipeline, Microsoft.OData.Mcp.AspNetCore.Hosting.McpHttpContextAccessor httpContextAccessor)
```

#### Parameters

| Name | Type | Description |
| - | - | - |
| `services` | `System.IServiceProvider` | The application service provider used to read `EndpointDataSource`. |
| `hostOptions` | `Microsoft.Extensions.Options.IOptions<Microsoft.OData.Mcp.AspNetCore.Hosting.ODataMcpHostOptions>` | Host catalog, include/exclude, and explicit routes. |
| `pipeline` | `Microsoft.OData.Mcp.AspNetCore.Hosting.ODataMcpPipeline` | The captured application pipeline. |
| `httpContextAccessor` | `Microsoft.OData.Mcp.AspNetCore.Hosting.McpHttpContextAccessor` | The wrapping accessor that can Start/End the inner context. |
