UnauthorizedAccessException on YellowFlavor.Serialization.dll

[salem-mdimegh]

Using Microsoft Visual Studio Enterprise 2022 (64-bit)
Version 17.9.6

Every time when I try to "Dump as" to any type.
Exception :

'System.Reflection.Assembly.LoadFile(@"c:\users\xxxxxxxxx\appdata\local\microsoft\visualstudio\17.0_607f993c\extensions\lzbpc2iq.5i1\InjectableLibs\net45\YellowFlavor.Serialization.dll")' threw an exception of type 'System.UnauthorizedAccessException'

@salem-mdimegh Thank you for reporting this issue.
Could you paste it to code you debugging and check what happens?

 using System;
 using System.Security.Permissions;
 using System.Security;


var f1 = new FileIOPermission(FileIOPermissionAccess.Read, @"c:\users\xxxxxxxxx\appdata\local\microsoft\visualstudio\17.0_607f993c\extensions\lzbpc2iq.5i1\InjectableLibs\net45\YellowFlavor.Serialization.dll");
try
{
    f1.Demand();
}
catch (SecurityException s)
{
    Console.WriteLine(s.Message);
}

Also, the information about the OS and .net framework version will be very helpful.

I can't reproduce, so, just waiting for the input from reporter.

Same bug was reported by Troy Loberger 10.04.23 in QA. netframework version of serialization library couldn't be loaded with the same exception.

I'm getting an authorization exception. I'm running VS as an administrator. Any thoughts?

'System.Reflection.Assembly.LoadFile(@"c:\users\MyName\appdata\local\microsoft\visualstudio\17.0_bc416d50\extensions\yt4v04nk.33h\InjectableLibs\net45\YellowFlavor.Serialization.dll")' threw an exception of type 'System.UnauthorizedAccessException'

@salem-mdimegh
Could you please also run?

var assembly = System.Reflection.Assembly.LoadFile(@"c:\users\xxxxxxxxx\appdata\local\microsoft\visualstudio\17.0_607f993c\extensions\lzbpc2iq.5i1\InjectableLibs\net45\YellowFlavor.Serialization.dll");

Or even better this code. I will know if it can be used as a workaround:

var fileData = System.IO.File.ReadAllBytes(@"c:\users\xxxxxxxxx\appdata\local\microsoft\visualstudio\17.0_607f993c\extensions\lzbpc2iq.5i1\InjectableLibs\net45\YellowFlavor.Serialization.dll");
var base64String = Convert.ToBase64String(fileData);
var asm = System.Reflection.Assembly.Load(System.Convert.FromBase64String(base64String));

That could be related to CAS policy

caspol -all -lg

Try adding this library to fully trusted in the developer command prompt console under Administrator:

caspol -m -ag 1.2 -url "file:///c:/users/xxxxxxxxx/appdata/local/microsoft/visualstudio/17.0_607f993c/extensions/lzbpc2iq.5i1/InjectableLibs/net45/YellowFlavor.Serialization.dll" FullTrust
