I'm using Unity 6000.3.0b2 beta and NuGetForUnity 4.5.0, and I'm trying to install packages, but entire window is broken (nothing is drawn).

The error:
MissingMethodException: Method not found: UnityEngine.Color UnityEngine.Color32.op_Implicit(UnityEngine.Color32) NugetForUnity.Ui.NugetWindow.DrawOnlineHeader () (at <bf09c69dec6043a5bf90fa5d088aa014>:0) NugetForUnity.Ui.NugetWindow.DrawOnline () (at <bf09c69dec6043a5bf90fa5d088aa014>:0) NugetForUnity.Ui.NugetWindow.OnGUI () (at <bf09c69dec6043a5bf90fa5d088aa014>:0) UnityEditor.HostView.InvokeOnGUI (UnityEngine.Rect onGUIPosition) (at <903ac5666bcd49cc9340cf587389e973>:0) UnityEditor.DockArea.DrawView (UnityEngine.Rect dockAreaRect) (at <903ac5666bcd49cc9340cf587389e973>:0) UnityEditor.DockArea.OldOnGUI () (at <903ac5666bcd49cc9340cf587389e973>:0) UnityEngine.UIElements.IMGUIContainer.DoOnGUI (UnityEngine.Event evt, UnityEngine.Matrix4x4 parentTransform, UnityEngine.Rect clippingRect, System.Boolean isComputingLayout, UnityEngine.Rect layoutSize, System.Action onGUIHandler, System.Boolean canAffectFocus) (at <9ec1e59f461c43279e7a8ed8178c8693>:0) UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr, Boolean&)

It looks like they removed implicit operator from color32 to color, other plugins also had the issues.

Here's the screenshot.
