CRM 365 Plugin: A project with an output type of class library cannot be started directly

Posted on by Mike Karls 180

I am using VS 2015 with the Developer's Toolkit for CRM 365 and I created a plugin, deployed it, and it works fine.

After restarting my machine, I then re-opened the Visual Studio 2015 solution, connected to my CRM environment, made a minor change to my code and then went to deploy the solution hitting F5 and got the error: "A project with an Output Type of Class Library cannot be started directly. In order to debug this project add an executable project to this solution which references the library project. Set the executable project as the startup project."

What does this mean and what do I need to do to deploy my plugin? Thank you in advance

    Nevermind, If I go Build then Deploy Solution it works. I'm just used to hitting F5 and deploying from that.

    Hi Mike,

    The plug-ins are class libraries (.dll), it can't be run like a console, windows, and web application. This .dll file is usually consumed by any of the applications I mentioned. In .Net application world, it is common to write business logic as .dll for their portability.  Coming back to plugins, you can build and then deploy the solution, (right click on the solution in Solution Explorer and click Deploy), it will be deployed to the solution that you had configured while connecting developer toolkit to the CRM.
