Several months ago we started to experience this error on all our SharePoint 2013/2016 farms.
Exception message: Loading this assembly would produce a different grant set from other instances. (Exception from HRESULT: 0x80131401)

SharePoint 2016 RTM and keys are available for downloading in MSDN!
SharePoint 2016 in MSDN
It is not officially anounced yet. I think the official anouncement of the general availability will be in a few hours on The Future of SharePoint event. If you haven’t registered for it yet, I would recommend to do it. Jeff Teper, the father of SharePoint, will unveil Microsoft vision and roadmap for SharePoint and OneDrive for Business on this event.
SharePoint team has just anounced SharePoint Server 2016 Beta 2 and Project Server 2016 Beta 2!
This is the last public preview of SharePoint Server 2016 before General Availability which is expecting to be in Q1 of 2016. Upgrade from SP Server 2016 IT Preview is not supported and you need to install beta 2 and migrate IT Preview content to the new Beta 2 deployment.
Note: This article is in draft yet and I’m still working on it.
Sometimes after moving SharePoint content (files, lists, sites, etc.) to a new place, you need to keep old links working. Sometimes you need to force users to use HTTPS instead of HTTP by redirecting them automatically. In these kinds of situation you can use the power of IIS URL Rewrite extension to achieve your goal.
In this walkthrough I’ll show you a way how you can keep old links to SharePoint content working after a migration of a site or part of its content to a new place. This solution can help you in different scenarios when you change the content URL, but don’t want to ask your users to update their links.
In my case, I used this approach when I did a migration of inherited SharePoint 2010 to a new server. During the migration there was an upgrade to SharePoint 2013 and total revision and reorganization of the content structure. A lot of files were moved to new libraries and folders, some department sites were split up, while others were combined. The main challenge in this migration was the strong requirement that all the old links should keep working. The requirement was fulfilled and by now it has already been working in production for about a year without any issues.
Some of you, probably, have already known that I took participation as a reviewer of a book related to SharePoint 2013 disaster recovery while it was preparing for the publishing. It appeared, that during this month I will use it as the main reference guide for my work.
I have just recorded a short screencast for the beginners in SharePoint which should help understand what is SkyDrive Pro and how to use it. Probably, it could be useful for some of you who don’t know what is SkyDrive Pro yet. Enjoy watching 🙂
Probably, some of you have already known about SharePoint Community and are already its members. Those of you who don’t know about it yet, should definitely at least take a look at it. It is a very fast growing community and it already has more than 3000 members. It has really nice articles, features and benefits.
One of the cool features I have been looking for since I started working on SharePoint was online chat with other SharePoint administrators and developers. This community has it! It is pretty active so you can talk with other SharePoint guys in real time!
Also it has a lot of benefits for members. Today, I was one of the lucky people and have won a prize. It is a book which was donated and written in part by Jasper Oosterveld. The book is called The SharePoint 2013 Handbook: An insight by the SharePoint community. I have not started to read it yet, but will definitely do that in a few days.
So, I invite you to join this awesome community, because it is really worth it!
I have experienced this issue several times on different farms. After some manipulations with the workflow using SharePoint Designer or a web browser, occasionally, it started to be impossible to open published workflow. The others workflows continued to work as expected, whereas when I tried to open the one that started to misbehave it showed the following error message “Failed to load the workflow definition for the workflow”.
