- **Disable full solution analysis**

Visual Studio performs analysis on your entire solution in order to provide a rich experience about errors before invoking a build. This feature is useful to identify errors as soon as possible. However, for large solutions, this feature can consume significant memory resources. If you’re experiencing memory pressure or similar issues, you can disable this experience to free up these resources. By default, this option is enabled for Visual Basic and disabled for C#.

To disable **Full Solution Analysis**, choose **Tools** > **Options** > **Text Editor**, then select either **Visual Basic** or **C#**. Choose **Advanced** and deselect **Enable full solution analysis**.

::: moniker-end

- **Disable CodeLens**

Visual Studio performs a **Find All References** task on each method as it is displayed. CodeLens provides features such as the inline display of the number of references. The work is performed in a separate process such as *ServiceHub.RoslynCodeAnalysisService32*. In large solutions, or on resource-constrained systems, this feature can have a significant impact on performance. If you’re experiencing memory issues, for example, when loading a large solution on a 4-GB machine, or high CPU usage for this process, you can disable CodeLens to free up resources.
