When creating solutions and or projects in Visual Studio 2019 the following error may occur.
“The length of the full path for the solution, project or item you are creating exceeds the maximum length allowed by the system. You must reduce the length of the name or the location”
In short this is poor by Microsoft, the project name is not even that long.
The solution is simple. Create your project with a short name. After it has been created rename the project to the desired name. Easy 😊. See the screen shots below.
