we've heard reports of deleting a Properties/AssemblyInfo.cs file, if you have that file, delete it and try again.When I build a mod this error comes up frequently:
Compiling ModName.XNAdll failed with # errors and C:\LocationOfModSourceFolder\ModName\obj\net45\ModName,AssemblyInfo.cs(13,11) : error CS0579: Duplicate 'System.Reflection.AssemblyCompanyAttribute' attribute warnings
I check the file and there doesn't seem to be a duplicate as far as I'm aware and I just delete the obj folder everytime this error appears and it's pretty annoying.
Not sure if this is a bug with tModLoader, or if there's something wrong with the mod.
This error usually comes up after I add something such as a item or recipe to the mod.
