# Install AWSSDK assemblies without NuGet


This topic describes how you can use the AWSSDK assemblies that you obtained and stored locally (or on premises) as described in [Obtaining AWSSDK assemblies](net-dg-obtain-assemblies.md). This is **not** the recommended method for handling SDK references, but is required in some environments.

**Note**  
The recommended method for handling SDK references is to download and install just the NuGet packages that each project needs. That method is described in [Install AWSSDK packages with NuGet](net-dg-install-assemblies.md).

**To install AWSSDK assemblies**

1. Create a folder in your project area for the required AWSSDK assemblies. As an example, you might call this folder `AwsAssemblies`.

1. If you haven't already done so, [obtain the AWSSDK assemblies](net-dg-obtain-assemblies.md), which places the assemblies in some local download or installation folder. Copy the DLL files for the required assemblies from that download folder into your project (into the `AwsAssemblies` folder, in our example).

   Be sure to also copy any dependencies. You can find information about dependencies on the [GitHub](https://github.com/aws/aws-sdk-net/blob/main/generator/ServiceModels/_sdk-versions.json) website.

1. Make reference to the required assemblies as follows.

------
#### [ Cross-platform development ]

   1. Open your project's `.csproj` file and add an `<ItemGroup>` element.

   1. In the `<ItemGroup>` element, add a `<Reference>` element with an `Include` attribute for each required assembly.

      For Amazon S3, for example, you would add the following lines to your project's `.csproj` file.

      **On Linux and macOS:**

      ```
      <ItemGroup>
        <Reference Include="./AwsAssemblies/AWSSDK.Core.dll" />
        <Reference Include="./AwsAssemblies/AWSSDK.S3.dll" />
      </ItemGroup>
      ```

      **On Windows:**

      ```
      <ItemGroup>
        <Reference Include="AwsAssemblies\AWSSDK.Core.dll" />
        <Reference Include="AwsAssemblies\AWSSDK.S3.dll" />
      </ItemGroup>
      ```

   1. Save you project's `.csproj` file.

------
#### [ Windows with Visual Studio and .NET Core ]

   1. In Visual Studio, load your project and open **Project**, **Add Reference**.

   1. Choose the **Browse** button on the bottom of the dialog box. Navigate to your project's folder and the subfolder that you copied the required DLL files to (`AwsAssemblies`, for example).

   1. Select all the DLL files, choose **Add**, and choose **OK**.

   1. Save your project.
