问题
I'm trying to publish a web application (with VS2012 Web) in which I need to run a vb script.
That script currently doesn't run correctly probably because of the lack of permissions. I am currently trying to run it as a user and supply some credentials. The password I have to provide must be in a System.Security.SecureString
which needs a char* to be created.
When I run my app in debug everything works fine and as expected. But when comes the time to publish the app to the server, it says :
1>C:\SVN\...\Default.aspx.cs(108,21,108,27): error CS0227: Unsafe code may only appear if compiling with /unsafe
I have allowed for unsafe code in the project properties, but I don't know why VS sees that property when debugging and not when publishing.
When I hit publish, I see the CS0227 error in the error list but it stays for only 1 second, then it disappears... It seems like that second is enough to make the build fail.
Any ideas as to what the problem is?
Here is my code :
Process proc = new Process();
ProcessStartInfo psi = new ProcessStartInfo("C:\\Windows\\System32\\cscript.exe", "\"" + scriptPath + "\" " + args);
psi.UseShellExecute = false;
psi.RedirectStandardInput = true;
psi.RedirectStandardOutput = true;
psi.RedirectStandardError = true;
psi.CreateNoWindow = true;
psi.Domain = "MyDomain";
psi.UserName = "MyUsername";
System.Security.SecureString hashPwd;
unsafe
{
// Instantiate a new secure string.
fixed (char* pChars = pwd)
{
hashPwd = new System.Security.SecureString(pChars, pwd.Length);
}
}
psi.Password = hashPwd;
//Set the process' start info
proc.StartInfo = psi;
//We start the script.
proc.Start();

It's very simple to publish with a unsafe code
Here is how you do it:

It seems when you publish it ignores the project setting of unsafe, so you need to manually open your .CSPROJ file and include:
<PropertyGroup>
...
<AllowUnsafeBlocks>true</AllowUnsafeBlocks>
</PropertyGroup>
That solved it for me.
Googled this issue but could not find anything. Checked the *.targets files for "unsafe" which led me to the "AllowUnsafeBlocks" tag.

Please add this code in Web.config file and check it is working for you
<compilers>
<compiler language="c#;cs;csharp" extension=".cs" compilerOptions="/unsafe" type="Microsoft.CSharp.CSharpCodeProvider, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
</compilers>
