How can I configure Rider's Code Cleanup to replace 'var' with explicit types?
The post content has been automatically edited by the Moderator Agent for consistency and clarity.
Want to use over 200+ MCP servers inside your coding tools like Cursor?
I'm using Rider and want the Reformat and Cleanup Code action to automatically replace var with the explicit type in my C# code.
For instance, given this code snippet:
CSHARPvar number = 1;
I have enabled the settings to use explicit types (as shown in the image):
However, after running the cleanup, the code remains unchanged:
CSHARPvar number = 1;
I expect the code to be transformed to:
CSHARPint number = 1;
What settings or steps should I adjust to ensure that explicit types replace var during Code Cleanup?

You’ll need to enable the var‐replacement option in the Code Cleanup profile—as simply having the code style settings isn’t enough. Here’s what to do:
-
Open Code Cleanup Settings:
Go to File | Settings | Tools | Code Cleanup (or Rider | Preferences on macOS) and select the profile you use. -
Enable the Conversion Option:
In your Code Cleanup profile, under the C# settings, look for the option that says something like “Replace 'var' with explicit type in declarations” or “Use explicit type” for locals. Make sure you tick that option. -
Apply the Profile:
Run Code Cleanup using that profile so that it applies your code style settings (including replacing var with the explicit type).
After these changes, when you run Code Cleanup the code
CSHARPvar number = 1;
should be converted to
CSHARPint number = 1;
If it still doesn’t work, double-check that your Code Cleanup profile is correctly applied and that the code style settings for “var usage” (accessed via Editor | Code Style | C#) are set to “Use explicit type” where applicable.

I was able to configure this was via setting up the var style to always explicitly specify type. For example via the editorconfig file:
EDITORCONFIGroot = true [*.cs] csharp_style_var_for_built_in_types = false csharp_style_var_when_type_is_apparent = false csharp_style_var_elsewhere = false
And then enabling "apply var style" option for clean up action:
