We recently updated our ComponentOne Studio ASP.NET MVC Edition to support ASPNET5 Beta5, you can use these controls in MVC6 now. Please follow the steps mentioned in my last blog on how to get started with TagHelpers & C1Studio ASP.NET MVC Edition controls inside MVC6. In the week of September 15th we will release Beta5 compatible C1 Templates for MVC6. Please note that this update is available through GrapeCity NuGet. You'll have to add the source path for GrapeCity NuGet to the Visual Studio 2015 Package Manager Source if not already added. The details about NuGet source path is available in the blog link listed above. This release supports ASP.NET Beta5 which is the default preview available for ASPNET5 in VS2015 RTM. In couple of weeks, we would update the MVC Edition controls to support ASP.NET5 Beta7 through the same NuGet.
