To add a solution to PureCM, right-click the solution and select 'Add to PureCM' or use the 'Add To PureCM' toolbar button.
This will launch the 'Add To PureCM' wizard. The first page will ask you to select the PureCM version you want to add your solution to. You can select an existing version or you can create a new version by right-clicking on the project and selecting 'New Version'.
After selecting the Version and pressing 'Next' you will be given a list of all the files which will be added to PureCM. You can uncheck any files you do not want to add.
Press 'Finish' to add the files to the PureCM version. PureCM has created a workspace in the folder containing the solution file. All the files have been submitted as a single changeset. You can see that the files are now under source control because they appear with a padlock icon.
