Mapsui: a project with an output type of class library cannot be started directly

[Kayumiy]

I cannot run this project.
Can anybody explain how to solve it?

As the error message says: you try to start a library.

You should not download a part of Mapsui. If you want to try a sample, than download the whole project and select a sample project for a platform (like the Mapsui.Samples.Droid for Android or Mapsui.Samples.UWP for UWP) as startup project.

[Kayumiy]

Even though, I opened whole project and selected a sample project, same error message has been shown.

Building project and Start Without Debugging takes a long time.

Any solution?

[charlenni]

Now you have selected Mapsui as startup project. Mapsui itself is a library, which couldn't be started.

So select the Mapsui.Samples.Uwp project, press the right mouse button and choose "Set as Startup project". Than start again.

Same error has not been solved yet.

[charlenni]

You didn't do, what I said. Now you try again to start the library Mapsui.Samples.Common.Desktop. That wouldn't work. You should select "Mapsui.Samples.Uwp" as startup project.

[Kayumiy]

When I select "Mapsui.Samples.Uwp" as startup project, it suddenly shows a lof of errors.

Go on the right side to "Solution", press right mouse button and select "Clean Solution". Than press right mouse button again and select "Restore NuGet Packages". Try again.

Btw. do you create a C# project before?

If this issue is solved, could you please close it?
