Possibility to remove Mutex in UpdateManager.AcquireUpdateLock?

[jpiechowiak]

Hi,

in our project we are using XWT for Windows/Mac and Framework.
On Mac it under the hood operates on Mono

Unfortunately Mutex is not available there. See:
https://github.com/mono/mono/blob/6be3e701766af6e3971e5ba260ece1a3ab095c08/mcs/class/corlib/System.Threading/Mutex.cs#L183

Is there an option to rewrite code, to not use Mutex?
This method

velopack/src/Velopack/UpdateManager.cs

Line 229 in f8acc97

using var _mut = AcquireUpdateLock();

throws an issue:

System.NotSupportedException: Specified method is not supported.
  at System.Threading.Mutex..ctor (System.Boolean initiallyOwned, System.String name, System.Boolean& createdNew) [0x00006] in <55335301af774faf8fc40779afb6f275>:0
  at (wrapper remoting-invoke-with-check) System.Threading.Mutex..ctor(bool,string,bool&)
  at Velopack.UpdateManager.AcquireUpdateLock () [0x00015] in <066f32c8dc0b43258461fe360bb30c54>:0  

Works perfectly fine on Windows.

What is the benefit to compiling on mono rather than using dotnet 6 native for example?

Probably no benefits, but it is quite large and a little bit old app. Migration will be challenging and time consuming right know.
