How to set up development environment to build plugins

First thing you need to do is to download the Visual Studio templates for building plugins. Please read the following article which explains how to download and install the extension.
If you already built you plugin please make sure the output path is set as follows:

<OutputPath>bin\Debug\</OutputPath> for debug and

<OutputPath>bin\Release\</OutputPath>

The plugin must be signed with the Sdl community key. You can download the key from our Github Repository. The name of the file is "SdlCommunity.snk"

Right click on project -> Properties -> Signing tab -> Check "sign the assembly" -> Navigate to the location of the key
