Question

Why does the file "ProjectName_TemporaryKey.pfx" get created in project? And what is its use in the project? I have EDM in my project and some forms, etc.

Answer 1

This is a file used for code signing:

Assembly signing (also called strong-name signing) gives an application or component a unique identity that other software can use to identify and refer explicitly to it. A strong name consists of its simple text name, version number, culture information (if provided), plus a public/private key pair. This information is stored in a key file; this can be a Personal Information Exchange (PFX) file or a certificate from the current user's Windows certificate store

Here is a bit more info.

Answer 2

You must be having click once based deployment.Such click once apps needs to be signed digitally by a certificate.If you dont have a certificate of your own the publishing system will create one for you. you can also take a look at this.
