Visual Studio does not load project because IIS Express is missing -

i removed iis express windows "programms installation" icon because want use full iis activated "programm installation".

then loaded vs solution. web api project got not loaded because configured iis express says error message.

when check .csproj file removed iis express.

but still content error, why?

the iis related this:

  <useiis>true</useiis> 

and not iis express. full iis.
