I am creating a C#/WPF project mainly for providing dialogs for use in other projects. I originally have an app.config but deleted it as the project is meant to be more like a library. I then got the errors

Metadata file
‘D:\projects\SimpleColorPicker\SimpleColorPicker\bin\Debug\SimpleColorPicker.exe’
could not be found

\SimpleColorPicker.exe’ does not
contain a static ‘Main’ method
suitable for an entry
point D:\projects\SimpleColorPicker\SimpleColorPicker\CSC

How can I fix this? I could leave the app.config in but I thought it will be neater to clean unneeded stuff

    You should create a class library (DLL) rather than an application. A DLL assembly is basically an executable without an entry point. Take a look at the output type in the project properties.
