asp.net web api - EntityFrameworkCore adds Multiple values in databas with async -


i using ef core storing product information. run code unit-test real sql server works fine. when run web service using startup dependency injection on iis deadlocks exception. , multiple values(rows) in database. can´t understand difference between executions.

this code unit-test works , set 1 row in database.

var options = new dbcontextoptionsbuilder<data.contexts.workordercontext>() .usesqlserver("data source=(localdb)\\mssqllocaldb;initial catalog=workorder;integrated security=true;") .options; workordercontext context = new workordercontext(options);  data.repositories.workorder.workorderunitofwork unit = new data.repositories.workorder.workorderunitofwork(context); ilegacywrapperservice wrapperservice = new legacywrapperservicecs();  services.services.workorderservice workorderservice = new services.services.workorderservice(unit, wrapperservice);  var options2 = new dbcontextoptionsbuilder<data.contexts.productinformationcontext>() .usesqlserver("data source=(localdb)\\mssqllocaldb;initial catalog=productinformation;integrated security=true;") .options; data.contexts.productinformationcontext contextproduct = new data.contexts.productinformationcontext(options2);  data.repositories.productinformation.productinformationunitofwork unitproduct = new data.repositories.productinformation.productinformationunitofwork(contextproduct); services.services.productinformationservice productservice = new services.services.productinformationservice(unitproduct, wrapperservice);  workorderscontroller controller = new workorderscontroller(workorderservice, wrapperservice, productservice, null); var resp = await controller.getexternalrefasync(id); var resp1 = await controller.getexternalrefasync(id); var resp2 = await controller.getexternalrefasync(id);  assert.notnull(resp);

and here startup file used when run web service

services.addsingleton<ihttpcontextaccessor, httpcontextaccessor>();  //default var connection = configuration.getconnectionstring("workorderdatabase"); services.adddbcontext<workordercontext>(options => options.usesqlserver(connection)); services.addscoped<core.data.repositories.workorderrepos.iworkordersunitofwork, data.repositories.workorder.workorderunitofwork>();  var connectionproductioninformation = configuration.getconnectionstring("productinformationdatabase"); services.adddbcontext<productinformationcontext>(options => options.usesqlserver(connectionproductioninformation)); services.addscoped<core.data.repositories.productinformationrepos.iproductsunitofwork, data.repositories.productinformation.productinformationunitofwork>();  services.addtransient<ilegacywrapperservice, legacywrapperservicecs>(); services.addtransient<iproductinformationservice, services.services.productinformationservice>();  services.addtransient<iworkorderservice, services.services.workorderservice>();

exception

transaction (process id 54) deadlocked on lock resources process , has been chosen deadlock victim. rerun transaction.

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
