How to prevent Visual Studio from automatically reformatting C# code

Question

In my Form.cs files, Visual Studio (2022) automatically reformats my code whenever I create a new event handler. Specifically, it deletes spaces and indentations. Original code looks like this:

private void OnTemperature(object sender,EventArgs e)

{

if(!steadystateflowsolved && !transientflowsolved) return;

double min = 0;

double max = 0;

GetFlowMinMax((int)AnalysisResults.TEMPERATURE, ref min, ref max);

string label = "Temperature";

string unit = "°C";

int tab = ModelForm.GetCurrentPage();

bool use3dmodel = (tab == 0);

bool usepid = (tab == 1);

if(steadystateflowsolved) {

if(use3dmodel) {

	Generate3DResults((int)AnalysisResults.TEMPERATURE,min,max);

	ModelForm.modelviewer.ImportResults();

	ModelForm.modelviewer.Render();

	IntPtr hwnd = ModelForm.GetResultsPanelHandle();

	ModelForm.DrawResultsScale(hwnd,"Temperature","°C", (float)min, (float)max);

	} 

else 

	Generate2DResults((int)AnalysisResults.TEMPERATURE, min, max);

}

}

After generating another event handler, it's reformatted like so:

//----------------------------------------------------------------------------------------------------

private void OnTemperature(object sender,EventArgs e) {

if(!steadystateflowsolved && !transientflowsolved) return;

double min = 0;

double max = 0;

GetFlowMinMax((int)AnalysisResults.TEMPERATURE,ref min,ref max);

string label = "Temperature";

string unit = "°C";

int tab = ModelForm.GetCurrentPage();

bool use3dmodel = (tab == 0);

bool usepid = (tab == 1);

if(steadystateflowsolved) {

if(use3dmodel) {

Generate3DResults((int)AnalysisResults.TEMPERATURE,min,max);

ModelForm.modelviewer.ImportResults();

ModelForm.modelviewer.Render();

IntPtr hwnd = ModelForm.GetResultsPanelHandle();

ModelForm.DrawResultsScale(hwnd,"Temperature","°C",(float)min,(float)max);

} else

Generate2DResults((int)AnalysisResults.TEMPERATURE,min,max);

}

}

Under Options | Code Style | Formatting, I have automatic formatting turned off, and it still does it.

Hi @Ed Hoppe, 

Welcome to Microsoft Q&A! 

Are you using the latest version of VS2022? 

I tested it on my side and was unable to reproduce your issue in the Visual Studio 2022 version 17.12.3. 

You can update your VS2022 to the latest version and check it again. 

If it persists, please report it by selecting “Help” menu > Send Feedback. 

I also found the similar issue. You can vote on this ticket and add comments to track the process.  

Sincerely,

Anna
