Devenv always rebuilds my project, because a typescript file is newer than a pdb file

Question

I have a project with typescripts. devenv constantly rebuilding this project. Diagnostics output contains this line:   
Project 'Benefits' is not up to date. Input file 'C:\abc\UI\BenefitsWeb\Scripts\Benefits\Modules\PPACA\ApprovalScreen.ts' is modified after output file 'C:\abc\UI\BenefitsWeb\bin\Dayforce.Web.Benefits.pdb'.
So, how do I resolve this issue? The aforementioned typescript file is truly newer than the PDB. But the PDB is not the output of the typescript compilation !!! 
Here is how I compile my typescript files:
    <PropertyGroup>
      <CompileDependsOn>
        $(CompileDependsOn);
        CompileTypeScript
      </CompileDependsOn>
    </PropertyGroup>
    <Target Name="GetInputs">
    </Target>
    <Target Name="GetOutputs">
    </Target>
    <Target Name="CompileTypeScript"
DependsOnTargets="GetInputs;GetOutputs"
Inputs="@(InputTypeScripts)"
Outputs="@(OutputJavaScripts)">
    </Target>
The project specifies the typescript files in the `TypeScriptCompile` item group, for instance:  
<TypeScriptCompile Include="Scripts\Benefits\Modules\PPACA\CalendarSetup.ts" />
Of course, @(OutputJavaScripts) lists the expected .js files only. No PDB files there.
So how come devenv matches a typescript file with a PDB file? How do I fix it?
I would like to clarify. It does not actually recompile the typescript or C# files (well for the first time it does recompile the typescript files, but only that). It starts the build, because typescript is newer than a PDB, but then it recognizes that no PDB
dependency has actually changed. The same is true for the javascript files - they are all up-to-date. So nothing is actually rebuilt, but why to enter the build sequence in the first place!

Hi mark,
>>The project type is C# (csproj).
C# is a programming language. The project type likes console application, windows forms application and web application.
Have all project types the issue? If it is, try resetting VS to the default settings with the following commands to see if it helps.
1.devenv.exe /resetsettings
2.devenv.exe /resetuserdata
