"Help Needed: SQL Server Connection Error :("

I am encountering the following error while trying to connect to SQL Server:

System.Data.SqlClient.SqlException: 'A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)'

A few months ago, a friend and I completed a project on his computer. He sent me the project along with the SQL file. Now, when I try to start the project, this error occurs. As a beginner to SQL, I don't think it's a major error to fix, but I tried a couple of solutions and it got more complicated. Can anybody help me?
