The error message says that there are no projects in the directory. From what I can see—and from what you have shared—I can only suggest that you check why the tool is trying to find the project in that directory, it seems to be in, "AWSServerless1\AWSLambda1" directory. The project is a .csproj
file, you can verify where that project file is and then check why that SDK is using a different directory.
Take a look at this
] sample code for more. This shows how you can use CLI and tools to build the project and then test it, this assume that you have downloaded the SDK too.
