Visual Studio Tip–Add existing on steroids

If you want to add multiple files to a traditional Visual Studio project(not .NET Core), the default procedure is the following:

• Right click on your project. Choose Add –> Existing Item…

• Choose one or more items from the ‘Add Existing Item’ dialog and click Add.

A faster alternative instead of using ‘Add existing’ is the following trick:

• Right click on your project and choose Unload project

• Right click on the unloaded project and choose Edit csproj file.

• Now add the following line to the MSBuild file:

<Compile Include="**\*.cs" />

• Visual Studio will load all .cs files it found.
