When Visual Studio opens a solution this extension will try to find a
.vssettings file with a name similar to solution's name located in the same
directory. For example if the solution being loaded is located in the file
C:\sources\repos\MyApp\MyApp.sln the extension will look for a file in a path
C:\sources\repos\MyApp\MyApp.vssettings and import it to your Visual Studio.
The extension can also restore your settings from a file specified in its
Tools->Options->Environment->Solution-specific VSSettings->Default .vssettings file path
on solution close. Note: This will happen only if there was found and applied a solution
specific .vssettings file on solution load.
The extension will apply the file from a Default .vssettings file path option
on solution open if Look for and apply .vssettings file on solution load
option is set to true, but no custom .vssettings file were found and applied.
If Default .vssettings file path option is not set - no changes will occur.
this can be controlled by the Apply default .vssettings if solution has no specific .vssettings option
To find out how to create your custom .vssettings file, please, refer to
