Resolved Could not load file or assembly System.Runtime.CompilerServices.Unsafe

[raysefo]

Hello guys,

I have a web API that was working without a problem. But today I am getting this error on the production server:

Could not load file or assembly 'System.Runtime.CompilerServices.Unsafe, Version=4.0.4.1, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

There is no such problem with the local machine. I tried to update this System.Runtime.CompilerServices.Unsafe but still having the same problem. Any ideas on how to fix it?

Best Regards.

Chances are that you actually changed something like updated a Nuget package or two, or had some patches applied to your machine.

See StackOverflow response on how to deal people have dealt with a similar issue when using Redis and its transitive dependencies.

Could not load file or assembly System.Runtime.CompilerServices.Unsafe

I created a Visual Studio (Community 2019) project with C# using ServiceStack.Redis. Since it is C#, I use Windows 10 (there is a Redis version for Windows but it is really old and as I know, it is

Thank you @Skydiver, adding this assembly to web.config solved my issue.

        <assemblyIdentity name="System.Runtime.CompilerServices.Unsafe" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-5.0.0.0" newVersion="5.0.0.0" />

thankz solved

            MySqlConnection connection = null;
            MySqlCommand command = null;
            MySqlTransaction transaction = null;
            string sqlstatement = "";

                connection = new MySqlConnection(WaterWorkDB.GetConnectionStringRemote());
                command = new MySqlCommand();

                connection.Open();

                transaction = connection.BeginTransaction();//Error this but now fixed

                command.Connection = connection;
                command.Transaction = transaction;

@remontesclaros : Other than the bump up to version 6 in your post, how is your solution any different from @raysefo 's solution from 3 years ago?
