    Hi @Juan Manuel Sanchez, 

    Welcome to Microsoft Q&A! 

    Which version of Visual Studio are you using? 

    You can try the following workarounds:

    1. Update your VS to the latest version.
    2. Repair your VS with Visual Studio Installer > More > Repair.
    3. Switch to higher target framework for your project.
    4. Please check if the project's references load correctly.
    5. Close all running VS instances and delete the hidden .vs, bin and obj folders in the project folder. Then, clean and rebuild the solution.  
    6. Create a new project and check if it occurs in new project.

     

    Sincerely,

    Anna
