How can i remove Microsoft Visual Studio Error?

The cause of the problem came from setting of the folder path which still untrust by you Visual Studio, OR your file have its own security you have to open before you can run it.

Let see how to make permission to your folder location:
Login as Administrator and start mscorcfg.msc. By default the location is: C:Program FilesMicrosoft Visual Studio 8SDKv2.0Binmscorcfg.msc
Now expand these: Runtime Security Policy, the Machine, the Code Groups, and the All_Code node.
Then Highlight the LocalIntranet_Zone node.
Go to right pane, select Add a Child Code Group
Select Create a new code group, enter a name for the code group, then Next.
Choose a condition type of URL, and enter UNC path to share the location of your project. The format is: file://\servernamesharename*
After click Next, choose Use existing permission set and select FullTrust.
Click Next and Finish. Restart Visual Studio

This is how to give permission to your file:
Browse to your project, right click it, chooses Properties.

Find Security below Attributes,

Then click Unblock
