Upon trying to open the Designer view of a project which I have opened many times before, I got the following error:

"The CurrentContext property of the LicenseManager is currently locked and cannot be changed. "

Call Stack:
"at System.ComponentModel.LicenseManager.set_CurrentContext(LicenseContext value)

Anyone know how to solve it?

Thanks.

Hi dsagefjyrf,

It seems there is no problem with your project. The problem is in the VS installed on you computer. Please try the following step to see if it helps.
1. If you have installed VS add-in, you can run in safe mode, so the add-in will be disabled.
2. Restore all VS settings, Tool->Import and Export Settings, select "Restore all settings".
3. You can try to create a new user account in Windows, login as that account to start VS. VS will initial all settings for that account.

Please tell me your test result.
It will be helpful to tell me after which operation you meet that error if you still remember that.

Sincerely,
Kira Qian

It appears that this is some sort of corruption on some of the solution files in the project.
To fix it you need to restore your project froma recent backup, before the error.

Something that is worth adding that I have just observed is that I cannot open the design of ANY projects as I recieve the above error.

Hi dsagefjyrf,

What type of form do you receive the error? Do you view the inherited form?

no - the main one. In the Solution Explorer (on the rhs), I have the following items listed:

Solution '(name of project)' (1 Project)
(name of project)
Properties
References
Program.cs
Solver.cs

When i right click on solver.cs and click "view design" i get the above error.

Hi dsagefjyrf,

Did you receive any error when compile? If no error, please try to copy the whole project to another computer running VS. Do you receive error on that computer?

I don't recieve an error when compiling.

I tried putting on a different computer with VS and it works fine. So I reinstalled it but still the problem occurs...

I have also started to receive a similar error...

The problem appears when you attempt to load a form or control in design view.
