project unavailable

Question

_{Sunday, November 1, 2015 1:54 PM}

I just installed VS yesterday and when I open my old project that I created yesterday, the project exploerer said it is unavailable and when I reload it, it says reload fail. Anyone knows what's going on?

I ran VS as administrator, doesn't work. Deleted .SUO file, does't work. Ran the tool thing under start menu and also doesn't work. Any help will be appreciated, thanks.

Hi DBlackD,

Do you have get any error message in Output window and Error List when project unavailable? Please provide the error information for unavailable.

Please create a new project with your Visual Studio and close this project. Then open this project again to check whether this problem occurred with all project or with just this specific project.

Please try with following steps to troubleshoot this problem.

1. Please confirm the project is built without any error before you close it. If there has some error in your project, it will result to the project load failed.
2. Please make sure the Visual Studio version is the same with the one used to open this project and the one used to create this project. Because different version has some incompatible.
3. Create a new blank project, add the old project items to the new one with add "Existing Items". Build the new one and then compare the .csproj file and .sln file between the old and new to check whether there has any difference.
4. Please open this project on another computer which installed the same version of Visual Studio, which can confirm whether this project is broken.
5. Open Visual Studio 2015 in safe mode with "Deven.exe /SafeMode" command to prevents all third-party VSPackages from loading when Visual Studio starts, thus ensuring stable execution.
6. Repair Visual Studio through Control Panel -> Visual Studio -> Change -> Repair.

I am running Windows 7 Home edition on my computer. I enrolled in the introduction to Mobile App Development class. I am stuck at where I am supposed to edit the project I made online in the App Studio in Visual Studio. Am I doing something wrong or do I need to upgrade to Windows 10?
