How to: Enable and disable full solution analysis for managed code
Full solution analysis is a Visual Studio feature that enables you to see code analysis issues only in open Visual C# or Visual Basic files in your solution, or also in code files that are closed. By default, full solution analysis is enabled for Visual Basic, and disabled for Visual C#.
It can be useful to see all issues in all files, but it can also be distracting. It slows Visual Studio down if your solution is very large or has many files. To limit the number of issues shown and improve Visual Studio performance, you can disable full solution analysis. You can easily reenable this feature if necessary.
To toggle full solution analysis
To open the Options dialog box, on the menu bar in Visual Studio choose Tools > Options.
In the Options dialog box, choose Text Editor > C# or Basic > Advanced.
Select the Enable full solution analysis check box to enable full solution analysis, or clear the box to disable it. Choose OK when you're done.
Results of enabling and disabling full solution analysis
In the following screenshot, you can see the results when full solution analysis is enabled. All errors and code analysis issues in all of the files in the solution appear, regardless of whether the files are open or not.
The following screenshot shows the results from the same solution after disabling full solution analysis. Only errors and code analysis issues in open solution files appear in the Error List.
Automatically disable full solution analysis
If Visual Studio detects that 200 MB or less of system memory is available to it, it automatically disables full solution analysis (and some other features) if it's enabled. If this occurs, an alert appears informing you that Visual Studio has disabled some features. A button lets you reenable full solution analysis if you want.
