"That assembly does not allow partially trusted callers."
- 0
I don't understand this...
Whenever i click my button i get the following error: "That assembly does not allow partially trusted callers."
What can be wrong? I'm reading the source code of an example application using the MySQL connector, and i'm trying to create a similar application. It's pretty embaracing :(
[
STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Form1()); <--- "That assembly does not allow partially trusted callers."FORM1.CS:
MySql.Data.MySqlClient;
using System;
...
usingnamespace
MysqlConnectionTest
{
public partial class Form1 : Form
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
string connStr = String.Format("server={0};user id={1}; password={2}; database={3}; pooling=false", "bla", "bla", "bla", "bla");
MySqlConnection conn = new MySqlConnection(connStr);
}
}
}

For this error message u can look here:
Im not really understanding ur code? Does the [StatThread] and the static void main function reside's outside the Form1 class? If so put in within the class and not outside.
Good luck!
- 0Take a look at your security settings of the .NET Framework, trust the assembly and it should work.

please verify the following:
1- that you are not referencing the assembly from a mapped network drive or from a network resource folder.
2- that you've strong named your assembly:
http://msdn2.microsoft.com/en-us/library/xwb8f617(VS.80).aspxPlease inform me if neither did work ..
good Luck - 0Probably a very stupid question, but where do i adjust the security settings of .net framework?
- 0In the Control Panel you find Administrative Tools, open this and you will see a Microsoft .NET Framework Configuration and Microsoft .NET Framework Wizards, you can use the one you like.

I did the following:
Increase Assembly Trust:
Assembly: C:\Program Files\MySQL\MySQL Connector Net 1.0.7\bin\.NET 2.0\MySql.Data.dll
Applies to: Computer
Minimum Level of Trust: Full Trust
But still, i get the same error :( - 0
add this to your AssemblyInfo.cs file:
[assembly: System.Security.Permissions.PermissionSet(System.Security.Permissions.SecurityAction.RequestMinimum, Name="FullTrust")]

So, what if you are in XPE and you don’t have the Microsoft .NET Framework Configuration or the Microsoft .NET Framework Wizards. How do you set the trust in .NET on your nifty admin application you just built?

Hello,
I placed your recommended line of code into my assemblyinfo.cs file and got the following error:
Application Identity:
System.IO.FileLoadException: Could not load file or assembly 'myApp, Version=1.0.2650.23992, Culture=neutral, PublicKeyToken=null' or one of its dependencies. Failed to grant minimum permission requests. (Exception from HRESULT: 0x80131417)
File name: 'myApp, Version=1.0.2650.23992, Culture=neutral, PublicKeyToken=null' ---> System.Security.Policy.PolicyException: Required permissions cannot be acquired.I am running an XBAP application..
Any ideas?
Kind Regards,
Glenn

Be aware that if your code is .net framework 1.1, but the user's machine has .Net Framework 2.0 installed then you will need to also trust the assembly in .net 2.0 (and 3?)
Because the .Net Configuration tool is not included in the 2.0 redistributables you may have to use the command line. To test if it is the 2.0 Framework causing you issues you can TEMPORARILY turn 2.0 Code Access Security off by:
Start - run - command
cd C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727
caspol -s off
re-run your 1.1 .net code.
- 0Hi,
I am using the Azure sample application on Win server 2008 OS.
I am trying to access scopes in my solution using the method in SDK samples, GetMyScopeList().
When I run it on my local fabric, I get same exception ,
" That assembly does not allow partially trusted callers".
I tried to set permissions in assembly but did not work.
Any help provided would be appreciated.
