Transcripts
welcome back in this video we're going
to take a look at how to get started
with the.net Upgrade Assistant tool now
in previous videos we've already looked
at the high level process we're going to
go through to upgrade from.net framework
to.net7 and we've talked about why you
might want to make that change
now we're ready to dive into the details
and start actually upgrading our sample
solution and to do that we're going to
begin with the.net upgraded system tool
and the reason we start with Upgrade
Assistant is twofold first this is the
tool that we're going to use to analyze
our solution and understand its
dependencies Upgrade Assistant is able
to show us nuget packages we depend on
as well as whether or not they're going
to work with our new Target and Net
Framework apis we're using and whether
they're available on our new Target or
not so Upgrade Assistant is the right
place to start to understand what work
you have ahead of you and what which of
your dependencies are going to work
with.net 7 and which ones are going to
need to be changed also for many types
of projects upgrade assistance is the
tool that you'll use to actually
automate some of the upgrade changes
themselves
now we don't recommend it for all
projects specifically for very large
class libraries and for any project that
has uh web dependencies we recommend you
use the newer asp.net incremental
migration tooling which we'll talk about
in a later video but for all other
projects we recommend Upgrade Assistant
so if you're if you have an asp.net app
or a class library with system.web
dependencies or a very large class
library that you may need to migrate in
Parts you can look at the other tooling
but for anything else for winforms
applications WPF apps WCF console
applications small to medium-sized class
libraries xamarin apps for all of those
Upgrade Assistant is a great tool for
helping you through the upgrade process
it does that by walking you through a
series of steps interactively
of things that need to change to move
from.net framework up to.net 7. as you
go each step will be applied and turn
automatically as much as is possible and
you'll be notified of things that you
need to change manually afterwards so
once you've finished running the tool I
do want to be clear that Upgrade
Assistant is not a magic Silver Bullet
that's going to automatically upgrade
everything but it will automate away
many of the simple changes so that then
you can focus on the really interesting
ones
for very small and simple projects
Upgrade Assistant May completely upgrade
your project but more likely what the
tool will do is interactively walk you
through a series of upgrade steps that
it applies and then at the end of that
you'll have to go in and upgrade a make
additional changes to complete the
upgrade and so we'll take a look at what
that looks like during these videos
so to start with you can go out to
learn.microsoft.com.net core slash
porting upgrade Dash assistant Dash
overview to see the documentation on our
doc site on how to get started with the
tool we include here some prerequisites
Upgrade Assistant has to be able to
build the project
um in order to upgrade it so we have to
be able to build the original project as
well as the project using its new Target
and so for that you typically will need
to be able to build on a Windows machine
so you need so Upgrade Assistant
currently only supports Windows and you
will need a recent version of the.net
SDK in Visual Studio 2022.
once you have those prerequisites the
documentation here will explain how to
get started installing and using the
tool for additional details you can go
check out the GitHub repo Upgrade
Assistant is developed as an open source
tool with Community contributions and so
by going to
github.com.net upgrade Dash assistant
you can see all the latest you can see
the latest changes that are being
checked in you can see conversations in
the GitHub discussions and in the issues
and ahead you can see um even more
detailed documentation explaining how to
use the tool as well as how to install
nightly builds if you want to try uh
sort of the nightly builds with the
latest fixes and features with the risk
of a little more instability we go over
how to install from our nightly feed as
well
so all of that's here as well as the
ability of course to create new issues
if you have feature requests or if you
run into any problems or you can submit
pull requests we love taking
contributions from the community and uh
it would be great if you get involved
that way
so let's go ahead and actually install
the tool now
upgradeassistant is a.net CLI SDK tool
so you're going to use it from the
command line this is different from some
of our other tooling like the asp.net
incremental migration tooling we'll look
at later that's a visual studio
extension with a GUI inside of vs but
for Upgrade Assistant it's all on the
command line and because it's a CLI tool
you install it using the.net SDK so
you'll run.net
or a.net tool install
uh now we do give a dash G because we
want to install this tool globally not
just for a single project and then you
just give the name of the tool and this
will actually download the package from
uh nougat where it's hosted and install
it as a global.net SDK tool for you
um okay so I get a message the Upgrade
Assistant has been installed with this
version and then you can run it by just
running upgrade Dash assistant it's
worth knowing that as a.net SDK tool you
can also update it uh when new versions
are released by running.net Tool update
again give the dash G and upgrade Dash
assistant or if you need to uninstall it
you can do the same thing with the
uninstall command instead of install
okay so let's go ahead and run the tool
and see what it does
so if we just run Upgrade Assistant by
itself we're going to get some usage
information we're told that a required
command was not provided and we get a
list of the commands that Upgrade
Assistant can run so there's four
primary commands that come built in
first there's the analyze command this
is the one that I talked about earlier
that's going to help you understand what
changes need to be made in your project
to upgrade it to Net 7 or netstandard or
net six uh the analyze command will use
many of the same features that the
upgrade command uses but instead of
being interactive and instead of
actually making changes to your project
the analyze command is just going to
look at your nuget package dependencies
it's going to look at your source code
at some VB specific considerations some
winform specific considerations and it's
going to generate a report listing all
of the things that need to be changed in
order to move from.net framework up
to.net 7. so it's a good way to sort of
understand the work we have ahead of us
we also have the upgrade command this is
sort of the primary command that you'll
be using to actually update a project to
Target a newer version of.net when you
run uh Upgrade Assistant upgrade you
specify either a solution file or a
project file a CS project or vbproj an
Upgrade Assistant will walk us through
step by step the changes that it's
making to get that project upgraded to
Target the latest versions of.net when
you run that you can choose whether you
would like to Target the long-term
support release which currently is.net6
the current release which would be.net 7
or a preview release which very soon
would be.net 8.
and we'll look at both the analyze and
upgrade commands in a lot of detail in
future videos
we do also have the extensions command
and we're not going to spend a lot of
time on this one in the future so I'll
just explain it briefly now if you run
Upgrade Assistant extensions you're able
to install and manage extensions from
nuget so Upgrade Assistant is designed
so that developers can customize Its
Behavior by adding additional upgrade
steps modifying the behavior of current
upgrade steps or Oops I did not uh
we have an error here which is
unexpected
let's instead of just running extensions
let's do it with dash dash help
um
but uh and you can even customize the
way things are working and so you can
see when we run help for the extensions
command you can do Upgrade Assistant
extensions list to list the installed
extensions as well as ADD you can use
remove and so on to add or remove
additional functionality from add-on
nuget packages which either you've
created or other people have created to
extend the functionality of Upgrade
Assistant
I can run you know as an example we can
run Upgrade Assistant extensions list to
see installed extensions
and we'll take a look at what we get
from that
and you can see that right now I have no
additional extensions beyond the default
built-in ones but you can use the create
command to make your own and we might
have a video on how to create extensions
but if you don't get your own you can
use add to use other people's extensions
the other command that's interesting and
upgraded system if I go back to Upgrade
Assistant uh dash dash help or just
Upgrade Assistant is the features
command so this command is used to turn
on and off uh preview features that
we're sort of working on at as
experiments so if I run.net or sorry if
I run upgrade
assistant
features list this is going to list the
different experimental features in this
release of Upgrade Assistant you can see
that we've enabled upgrading for
cross-platform deployment a
solution-wide SDK conversion and an
analyze binaries command so none of
these are turned on right now so none of
these are going to work but by setting
an environment variable UA features I
can enable these and try using these one
in particular that we're going to be
looking at in a future video is the
analyze binaries command it's a very
useful one that can be used to look at
all of the.net apis that you're calling
from your project and whether they're
available on the new version of.net that
you're moving to or not so it's similar
to what the analyze command does but
rather than being a broad overview of
all the things Upgrade Assistant looks
at
it's a very deep analysis of the.net
dependencies that you have and so I
personally like to use both analyze and
analyze binaries and so in order to show
how we would enable that I will set UA
features to analyze binaries if I wanted
more than one of these I could delimit
them with semicolons
and now if I run Upgrade Assistant
features list you will see
in a moment that analyze binaries is set
to true and in fact if I just run
Upgrade Assistant and it lists what
commands I can run you can see that
analyze binaries is provided as one of
the commands now that's available
all right
um so at this point I think we're ready
to dive in and get started which we will
do in the next video but just to recap
to get started with Upgrade Assistant uh
I would recommend going out to either
our GitHub page or to the documentation
on learn.microsoft.com to sort of read
up on how to get started and then you
just need to run a.net tool install Dash
G upgrade Dash assistant to get it
installed and I'll see you back here in
the next video when we start doing some
analysis with the tool
