Port to 2.0.1: TagHelper error: A local or parameter named '__model' cannot be declared in this scope because that name is used in an enclosing local scope to define a local or parameter

[Eilon]

Port this fix to 2.0.1: #1614

[NTaylorMullen]

Will complete this work when we have 2.0.1 infrastructure in place.

[bdominguez]

Estimated date for release? This is a show stopper for me on upgrading to 2.0.

[Eilon]

@bdominguez we plan to release this in mid-September. Hard to pin down an exact date. However, we'll have pre-release builds of the patch before then, and we'll share details about that once the builds are ready.

[bdominguez]

@Eilon thanks.

[Gaelmart]

This has stopped 6 months of work dead at the last step.
Is there a hack or ANYTHING that can get me past it.?

[Eilon]

For folks running into this, can you show what code you have in your @section so that we can try to offer workarounds? The exact workaround (if one is available) would depend on what code is in the section.

[Gaelmart]

The __model errors happen on the lines and only errors on publish to Azure (it builds fine)

<label asp-for="Password" class="col-md-2 control-label"></label>
<span asp-validation-for="Password" class="text-danger"></span>

@model iBasisMobileV14.Models.AccountViewModels.SignupViewModel
@{
    ViewData["Title"] = "iBASIS Spares Search";
}

@{
    Layout = "~/Views/Shared/_SignupLayout.cshtml";
}
@*This is due to Angular Universals prerendering,
    and things such as window and jQuery not being
    available on the server side.
    You can follow angular/universal#534 as we try to make these things
    available or at the very least ignored on
    the server side to prevent errors.For now you can remove the asp-prerender attribute on the Index View to
    disable server side rendering if you need these libraries to work for now.

@Gaelmart thanks. @NTaylorMullen - any idea if there's a workaround that could be used for this?

[NTaylorMullen]

@Gaelmart one workaround you could do would be to throw all that TagHelper code that utilizes asp-for into a partial. I know it isn't ideal but it will work! 😄

[Eilon]

@NTaylorMullen ah that's probably a pretty good workaround that should work in most cases, though it's of course a bit messy.

[Eilon]

This patch bug is approved for the 2.0.x patch. Please send a PR to the feature/2.0.1 branch and get it reviewed and merged. When we have the rel/2.0.1 branches ready please port the commit to that branch.

[Eilon]

@ajaybhargavb - I reassigned this to you because @NTaylorMullen is still out.

[ajaybhargavb]

888e6bf on branch feature/2.0.1.

[rajsingh216]

Please may I ask how can we get the fix?

[poke]

@rajsingh216 Update to version 2.0.1 once it’s released…

[poke]

@Eilon In response to this comment, is there any update on when 2.0.3 is going to be released? I heard you had some release infrastructure problems which are resolved now, so do you have any date you can share? My team is getting a bit anxious since we are still holding off the upgrade because of this.

[Eilon]

@poke we unfortunately still have some infrastructure issues, but we are working right now on getting a preview build of 2.0.3 that people can try out. We don't have an exact date to share on the final release of 2.0.3 just yet.

[poke]

@Eilon A preview release would work just fine for me! Anything to allow me to move to 2.0 is great! Thanks for the update and good luck with your infrastructure :)

[Eilon]

@poke thanks, we're working through it! I will update all patch issues with download details when we have a build available to test.

[stefan505]

@Eilon any news on this? I had to jump through some hoops to successfully upgrade to 2.0 as a result of this, but its not sustainable.

[Eilon]

@stefan505 we're working on this right now. It's a bit complicated due to some infrastructure issues but it's a high priority for us.

[Eilon]
