.NET SDK

A synchronous function execution SDK is used as an example. To use the sample code, you must add the SDK dependency with the same language.

**Table 1** .NET SDK information
SDK Info	Description
Installation	Using .NET CLI dotnet add package HuaweiCloud.SDK.FunctionGraph Using Package Manager Install-Package HuaweiCloud.SDK. FunctionGraph
Links	SDK Dependency .NET SDK User Guide

The request/response parameters and example requests/responses of the SDK are the same as those of the corresponding APIs. For details about the parameters and examples, see the API for executing a function synchronously.
