Visual Studio is one of the best IDE for developers. It has Git integration through Team Explorer. But Microsoft recently working on Git tools for Visual Studio 2019 which is separate from Team Explorer. It is currently in preview mode.
While working with Visual Studio often we need to use other tools. If you go to Visual Studio ‘TOOLS’ menu option you can see that already there are some external tools. You can add other tools there of your choice and need. For example I want to use assembly disassembler while working with Visual Studio. I can open ILDASM every time from navigating the location which is need inside the folder structure of ‘Program Files’ and ‘Microsoft SDK’ or I can attach this to Visual Studio external tool and open right from there. It will save a lot of time and make you productive. To attach a new external tool, go to ‘TOOLS’ menu then ‘External Tools’ and a pop up will open where you can give a name of your menu option for the tool, give location of the tool etc. Depending on what type of tool you are attaching you may need to give other information. Then click on ‘OK’. Now you can see a new menu option under Visual Studio ‘TOOLS’ menu which points your newly added external tool. When you click on there it will open.
