回答1:
I have resolved this issue.The SignFile is not installed correctly.enter image description here
Double Click SignFile directly to install leads to the issue.Select File in the Project followed the png's guid is right.
回答2:
What framework does your project target? It seems to be similar issue described here.
Please make sure you've installed the corresponding target-framework SDK, also you may need to install the .Net 4.0 SDK and restart PC to build the project again.
In addition: It seems you haven't install .net 4.6.1 SDK, so if possible you may need to install the .net framework 4.6.1 SDK also. Go Tools=>Get Tools and Features=>Individual Components to install the .net framework 4.6.1 SDK package.
