## Methods

`Task<TSchemeMedium> GenerateAsync(string schemeCode, string tenantId = null)` 

Asynchronously generates the source process scheme identified by `schemeCode` in the tenant scope specified by `tenantId`.

### Parameters

| Name | Type | Description |
| --- | --- | --- |
| `schemeCode` | `String` | The code of the process scheme to generate. |
| `tenantId` | `String` | The tenant identifier that scopes generation, or [null](https://learn.microsoft.com/dotnet/csharp/language-reference/keywords/null) for generation without a tenant scope. |

### Returns

| Type | Description |
| --- | --- |
| `Task<TSchemeMedium>` | A [Task<TResult>](https://learn.microsoft.com/dotnet/api/system.threading.tasks.task-1) whose result is the generated source process scheme. |
