Could not set default culture in blazorserver

Quote:

Hello everyone I am working on the project that I need to use multiple language and then I want to set default culture. Everything is working fine but I couldn't set default culture. Project is starting with default English language, even though I changed it to Russian language as I showed code below. Please help me thank you.
