Description

When opening a project for the first time, an exception is thrown:

Failed to analyze Temp.txt: System.IO.FileNotFoundException: Could not find file 'C:\Projects\sonarlint-visualstudio\src\Integration.Vsix\bin\Debug\VS2019\net46\Temp.txt'.

TODO:

• Check if there is a way not to invoke analysis on temp files
• Verify that the file exists before attempting to read it
