I know this is an old question but for new people I recommend the extension "MiddleClickDefinition" in visual studio. Here’s how you can set it up:

Install the Extension:

• Open Visual Studio.
• Go to Extensions > Manage Extensions.
• Search for MiddleClickDefinition and install it.
• you have to close accept a windows pop up of VSIX installer (not sure if it will automatically open after restart or when you open visual studio again)

Enable the Extension:

• After installation, go to Tools > Options.
• Navigate to MiddleClickDefinition settings.
• Enable the option to use middle-click for "Go To Definition".

Use the Middle Mouse Button:

• Now, when you middle-click on a method or variable in Visual Studio, it will trigger "Go To Definition" just like pressing Ctrl + F12

Extension in Tools>Options>MiddleClickDefinition
