What steps do I need to take to convert from a class library to a WCF?

app-config, c#, hosting, wcf

Solution

I discovered the following doing the opposite to what you are trying to achieve, i.e. changing a service library to a console application..

some of the settings in the csproj files cannot be edited from the settings screen from within VS to convert an class library to a WCF Service Library you need to add the following to your project file

Add the following to the first `PropertyGroup` [these are the guids for a C# WCF Project]

<ProjectTypeGuids>{3D9AD99F-2412-4246-B90B-4EAA41C64699};{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}</ProjectTypeGuids>

See here for further information on ProjectTypeGuids

You may also need to add the following line immediately below:

<StartArguments>/client:"WcfTestClient.exe"</StartArguments>

But ultimately it's the PropertyTypeGuids that you need to manually insert to get VS to recognise the project as a WCF Service Library Project.

Problem

I created a project as a Class Library. Now I need to make it into a WCF. I can create a WCF project, but I would like to avoid all that fuss with TFS. I've done the App.config and added the /client:"wcfTestClient.exe" line to the Command line arguments. But there seems to be something else missing from it launching the Hosting.
