How do I fix "Unrecognized Guid format" - visual-studio-2013

I keep getting this error in VS 2013 if I click on the following file types:
*.cs
*.cshtml
*.config
*.asax
*.html
I just recently updated to Visual Studio 2013 Update 2 and fixed a compatibility issue to always run the "devenv.exe" as administrator because of UAC issues and running a service in windows 8.1. However; I can turn around and open this entire solution in SharpDevelop 4.4 and there are no issues. That would lead me to believe that the solution file wasn't the issue and it points to VS 2013 being the culprit on some level.
I have tried the following:
devenv.exe /ResetSettings ( Did not work )
Reset all settings to default without saving current settings ( Did not work )

It only worked for me when I unchecked all checkboxes and on the next screen at least one option was required so I checked "No I am done investigating the problem"
Note that this is based on other answers so first follow those procedures to open the "troubleshoot compatibility" screen for the devenv.exe

We were able to fix this by doing the following
Navigate to devenv.exe by right clicking Visual Studio from start, click properties, and select "Open File Location...".
Right click on devenv.exe and select "Troubleshoot Compatibility".
Click "Troubleshoot Program"
Check "The program opens but doesn't display correctly"
Click "Next"
Click "Test the program"
Confirm everything opens correctly
Click "Next"
Click "Yes, save these settings for this program"

I did an upgrade from Windows 8.1 to 10 recently, everything went smoothly. I can open my Visual Studio projects and debug them just fine until I run the Visual Studio 2013 Update 5 suddenly I get "Unrecorgnized GUID Format" error every time I open up any aspx/cs.
This is the steps I did to resolve the issue:
In Windows 10, you have to right-click devenv.exe and select "Troubleshoot compatibility".
select "Troubleshoot program" and make sure that "it worked with older versions of windows" is unchecked.

As stated in this Connect article, you have to run the troubleshooter again and validate that the fix worked. Additionaly, you should not check the box saying "it worked with older versions of windows", it would block some API required by VS.

How do I enable the debugger in Visual Studio 2019?

The debug type field is greyed out as are the build buttons. I opened a folder in visual studio 2019 with my project and source code files. I have not installed any extensions yet either. I read somewhere to select a startup item but none of the items in the solution explorer are valid except for Gradebook.dll in the debug folder although that doesn't seem to do anything.
Did you try to click the run button or press F5.
If so it should prompt you to select CPU. Then, run it again and it should work.
If that doesn't work try going into "Program.cs" in the Solution Explorer and make sure the Application.Run line is there.

Make Visual Studio 2019 Always Run as Administrator from Start Bar Recent Solutions List

I recently upgraded to Windows 10 and Visual Studio 2019.
Prior to the upgrade, Visual Studio 2017 would always run as Administrator. I did not think much of this, but now that it is gone it is causing me problems.
The primary one is that it will not load my projects that use my local instance of IIS.
I usually launch Visual Studio from my start bar. Right now this goes like this:
Right click on the icon on the start bar and select my solution.
It loads and then I realize that the main project did not load.
Close visual studio, open as admin
Pick my solution and then it loads.
I would really like to only have to do #1 above. Is there someway I can edit the shortcut on the start bar to have it always launch as Administrator?
Turns out that Visual Studio uses different permissions when you click on the list of shortcut options it offers in the start menu. (IE to load a recent solution directly.)
Selecting the Properties->Advanced->"Run as Administrator" did not cause these to run as administrator.
But this did it:
Find devenv.exe (Visual Studio's executable)
Right Click on it and select "Troubleshoot Compatibility".
On the Program Compatibility Troubleshooter window, click on Troubleshoot Program
Check that the program requires additional permissions and click Next
On the next window, click on Test the program… and VS will open as administrator
Click next and then click on Yes, save these settings for this program
Now Visual Studio will ALWAYS run as administrator.

How to Fix Unrecognized Guid format in Visual Studio 2015

I'm getting an "Unrecognized Guid format" error when I try to open my project in Visual Studio 2015 on a Windows 10 machine (upgraded from Windows 7).
This did not always occur for me. I originally made VS studio open as administrator (because my project needed it at the time) by following the steps in the anwser here: Can you force Visual Studio to always run as an Administrator in Windows 8?
I then decided I wanted to switch back to not having it open as admin. To try and switch back I again ran the compatibility troubleshooter, this time I selected "try recommended settings". After doing this I am now getting the Guid error every time I open my project and I can no longer run it. I even get it if I open VS as admin like I did before.
I even tried uninstalling Visual Studio and reinstalling it but that did not work either.
I am guessing you used to run Visual Studio as Administrator. This did it for me. The answer is to delete the compatibility entry in the registry.
Type Windows+R on the keyboard to open the Run dialog
Type regedit and press enter
Browse to HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers
Delete the Visual Studio entry
I fixed this on Windows 10 by using the Troubleshoot compatibility tool. It has to do with an extra checkbox being enabled.
Navigate to devenv.exe by right clicking Visual Studio from start, click
properties, and select "Open File Location...".
Right click on devenv.exe and select "Troubleshoot Compatibility".
Click "Troubleshoot Program"
Uncheck "it worked with older versions of windows"
Click "Next"
Click "Test the program"
Confirm everything opens correctly
Click "Next"
Click "Yes, save these settings for this program"

Visual Studio 2012 MSVSMON.EXE does not work

I'm really tired of this error.
Most of the time, when I want to debug the program , I'm faced with this message.
Microsoft to offer solutions, but it is quite confusing:
1.
Make sure the Visual Studio Remote Debugging Monitor is installed and running on the remote machine.
2.
Make sure the Remote Server Name is correct in the Name box in the Project Properties dialog box.
3.
Verify that the remote machine is accessible on the network.
please someone help and guide me because all of my projects have been suspended and i need visual studio debugging.
meanwhile, when i dc from internet, visual studio will work.
Windows 7 x64, VS 2012, VB.NET
I fixed it like this:-
Create a shortcut on your desktop to "C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\Remote Debugger\x64\msvsmon.exe".
Right-click shortcut and select "Properties" from the dropdown menu.
Select the "Compatibity" tab
Tick "Run this program as administrator"
Click OK
Create a shortcut on your desktop to "C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\devenv.exe".
Right-click shortcut and select "Properties" from the dropdown menu.
Select the "Compatibity" tab
Tick "Run this program as administrator"
Click OK
To start VS2012:-
1) Double-click the msvsmon shortcut icon (that you created above, to launch msvsmon)
2) Double-click the "Visual Studio 2012 Professional" shortcut icon (that you created above, to launch VS2012)
3) In VS2012, ensure standard toolbar is visible.
4) In VS2012, ensure "Solution Platforms" dropdown (on standard toolbar) is visible and set to "x86".
and ... wowee ... debug works !
I had the same problem. I fixed changing in properties/compile/target platform to x86 instead of Any CPU. It was the problem in my case. Hope it helps.
I got this error when starting VS2012 as a normal user. When starting as an administrator it opened up a UserControl TestContainer window instead.
What have happend was that the startup project was changed. I changed back to my ordinary startup project by right-click on it and choose "Set as StartUp Project".
I have started vs 2012 as administrator and it is fixed

Visual Studio 2010 "Solution platforms" popup missing

I'm getting a weird problem with Visual Studio 2010 Premium. I use two PCs, on the first there is no problem on the second the "Solution Platforms" popup menu disappeared, the configuration is the same (Windows 7 x64). The problem occured when I opened a project from a mercurial repo, I was not able to restore the popup. I reset the Visual Studio settings and done a Repair from the installer. No change. If I create an blank project (framework 2.0, 3.0, 3.5, 4.0) the "Solution Platforms" popup is still missing.
Also if I change the target platform with Build --> Configuration Manager there is no effect on the build (no compilation for x86 for example).
Any ideas (no full reinstallation please ) ?
thank you.

Try the following:
From the list, select "Customize..."
On the screen that appears, click the
"Add Command..." button.
Select "Build" from the Categories
list, then scroll to "Solution
Platforms" in the Commands list and
click "OK"
Close the dialog and check your list, it should now be available.
The accepted answer is the wrong way to restore the platforms combobox. What you should do is find the little dropdown menu next to the configuration combobox and choose "Add/Remove buttons" From that list, check "Solution Platforms" and everything will be in its rightful place :)
